Refinement and completion of the online auto parts store on Next.js + Carstore API + PostgreSQL

Budget: 20000 UAH Deadline: 5 days

Hello!

We are the ViACore team — we specialize in website development, online stores, catalogs, CRM/ERP solutions, integrations, automation, and technical architecture.

Your request is very close to us, as it requires not just "laying out pages," but bringing the project to a working business result: a stable auto parts catalog, integration with the Carstore API, cart, checkout, Nova Poshta, online payment, deployment, documentation, and secure project transfer.

We can start correctly — with a mandatory technical audit of 1–2 pages, where we will document:

the current state of the code;
architectural risks;
the state of integration with the Carstore API;
what is already working and what needs to be completed;
blockers;
completion stages;
time and budget estimates;
what is needed for final deployment and transfer.

We work in stages, with written documentation of decisions and blockers. It is standard practice for us: Git, README, .env.example, deployment structure, migrations, launch documentation, final access transfer, and a clear user scenario from catalog to purchase.

We have experience with Next.js, PostgreSQL, API integrations, e-commerce logic, catalogs, payments, delivery, and deployment.

Examples of work / demos:

https://automoto.shops.demosites.viacore.group/

https://autopro.shops.demosites.viacore.group/

https://cosmetologyshop.shops.demosites.viacore.group/

https://omnistore.shops.demosites.viacore.group/

We can also offer a starter package for a quick launch:

Hello. I have been working with React/Vue/Node.js for over 9 years. I also have extensive experience with Next.js. I am ready for collaboration.

Budget: 20000 UAH Deadline: 30 days

I will conduct a technical audit of the architecture on Next.js, complete the integration of the Carstore API with PostgreSQL, and set up the end-to-end checkout logic with Nova Poshta to a working user scenario.

What method do you plan to use to bypass the limits of the Carstore API when deeply filtering the catalog: through data indexing in your PostgreSQL for instant search or through direct server requests that may "hang" the UI under high traffic?

Budget and deadlines will be discussed in private correspondence. 🤝

Hello, I have worked on an online store for an auto service with a catalog of spare parts of 5000+ items and integration with suppliers - a project similar to your needs with Next.js and a database.

I am curious if you plan to integrate filters for searching spare parts by VIN code or car model along with the Carstore API?

I suggest we get in touch, I will provide you with free technical consultation and we will create a development plan + I will tell you about my team! ⚡

Budget: 27000 UAH Deadline: 20 days

Greetings! I am ready to take responsibility for bringing your project to a stable working state. I have experience working with high-load systems and complex integrations, including in the automotive field, so I understand the specifics of working with cross-references and large catalogs through API. My approach is systematic and focused on the end-user scenario, rather than just "writing code."
Implementation plan and technical stages:
• Mandatory audit: I will start with an analysis of 1-2 key pages and the current database architecture (PostgreSQL). I will compile a list of blockers and discrepancies with the Carstore API for written documentation.
• Catalog and filtering: Setting up correct data mapping, debugging search, and working with product characteristics.
• Sales cycle: Implementation of the cart, Checkout logic, integration of the Nova Poshta API (selection of branches/parcel lockers) and payment gateway (LiqPay/WayForPay).
• Infrastructure and DevOps: Setting up database migrations, preparing .env.example, documentation in README, and deployment to stable hosting (Vercel/VPS).
Cost and timelines:
• Audit and architectural analysis: 5,000 UAH.
• Completion of development and launch: 45,000 UAH.
• Timelines: 15-20 working days (depends on the results of the audit).
Why I am suitable for this role:
• Professional approach: I work in stages with clear progress documentation. Project handover includes all accesses, environment variables, and deployment instructions.
• Experience in the automotive field: I understand the logic of selecting spare parts and working with external data catalogs.
• Responsibility for the result: My goal is not just to close a ticket, but to provide you with a working tool that correctly processes orders and accepts payments. I am ready to start the audit and document the current state of the project. I am in touch! Expand

Budget: 20000 UAH Deadline: 1 day

Good day. I can participate in the project.

The work format is clear: not just "finish the front end," but to bring the online store to a working state with a normal end-to-end scenario — catalog, product, cart, checkout, delivery, payment, deployment, and project handover.

I have experience with Next.js, API integrations, PostgreSQL, e-commerce logic, checkout flow, payment integration, Nova Poshta, Git, and structured project handover.

I am ready to start with an audit of 1–2 pages:
— check the current code;
— assess the architecture;
— identify blockers;
— describe risks;
— propose a work plan in stages;
— document what needs to be completed for a stable launch.

I work only through Git, with README, .env.example, proper environment variables, migrations, deployment, and final access/instruction handover.

I am ready to work in stages, document blockers in writing, and be responsible for the end-user scenario, not just for individual pieces of code.

After the audit, I will be able to provide an accurate estimate of the timeline and cost. Expand

Budget: 20000 UAH Deadline: 21 days

Hello!

I am ready to join the project as a contractor who is responsible for the work result, not just for individual frontend fixes.

I understand the task: an online store for auto parts on Next.js + Carstore API + PostgreSQL, where it is important to bring the project to a full user scenario: catalog → product card → cart → checkout → delivery by Nova Poshta → online payment → deployment → project handover.

I am ready to start with a mandatory audit of 1–2 pages and document:

— the current state of the project;
— what is already working;
— what is broken or partially implemented;
— architectural risks;
— blockers;
— a list of improvements by stages;
— an estimate of timelines and costs for each stage.

What I can take on:

— audit of the current code, API integration, and database;
— checking the architecture of the Next.js project;
— setting up a proper Git repository structure;
— README, .env.example, launch instructions;
— PostgreSQL migrations;
— integration of Carstore API;
— catalog of auto parts;
— search, filters, categories;
— product card;
— cart;
— checkout;
— integration with Nova Poshta;
— connecting online payment;
— order processing;
— deployment;
— final technical handover of the project.

I work in stages:

Project audit — checking code, API, database, environment, deployment, and current issues.
Improvement plan — a written list of tasks, blockers, timelines, and priorities.
Basic stabilization — Git, README, .env.example, migrations, project launch.
Key e-commerce scenario — catalog, product, cart, checkout.
Integrations — Carstore API, Nova Poshta, online payment.
Testing and deployment — checking scenarios, fixes, launch.
Project handover — documentation, access, instructions.

I agree with your approach: without Git, README, .env.example, migrations, deployment, and final handover, the project cannot be considered complete.

Cost of the audit: from 3,000 UAH
Audit duration: 1–2 days

After the audit, I will be able to accurately assess the full scope.
Approximately, the completion of such a project may be from 40,000 UAH, depending on the state of the current code, readiness of integrations, database structure, and the volume of already implemented functionality.

Estimated timeline for full improvements: 3–6 weeks after the audit.

Budget: 20000 UAH Deadline: 1 day

Good day!
I read the technical specifications, and I support the format with a mandatory audit before the main phase; I work this way with legacy projects myself.

What I propose for the first phase:
code audit + database schemas + integration with Carstore API
written report: what is ready / what is not ready / what requires rework / estimated hours to completion
fixed cost for the audit, timeframe 2-3 working days

Regarding the budget, I want to be honest right away: the specified amount for the full scope from the technical specifications (catalog, product card, cart, checkout, Carstore API, NP, online payment, deployment) looks tight. After the audit, there will be a clear picture regarding the hours, and then we can decide together how to proceed: review the budget, narrow the scope to what can realistically fit, or break the work into phases. This is a normal working process; I do not want to promise deadlines and quality blindly.
Questions before the audit that will speed up the assessment:

Is there a repository or code in an archive?
What is your estimated % of readiness?
Is there access to the Carstore API documentation?

If the format is interesting, I am ready to continue in private messages. Expand

Budget: 24998 UAH Deadline: 9 days

Good day.

I suggest starting with an audit of 1-2 pages:

1. State of the repo and infrastructure — Git, README, .env.example, migrations, deployment.
2. Critical path: catalog → card → cart → checkout → Nova Poshta → payment. Identification of blockers.
3. Written report: risks, priorities, breakdown of work by stages with estimates.

After the audit — we will document the scope and conditions for the stages in writing. Each stage with acceptance criteria before starting, transfer of access according to the checklist at the end.

Strengths: server integrations, working with APIs (Carstore, Nova Poshta, payment), OAuth, PostgreSQL, setting up conversion analytics. I work with the team at axal.agency.

I am ready to start this week. For an accurate estimate, access to the repo or a description of the structure is needed. Expand

Budget: 20000 UAH Deadline: 12 days

Viktor, good afternoon.

The store is already operational, but not completed. Customers are leaving every day because they couldn't complete the checkout. The task is not to "finish the front," but to close the entire purchase scenario: from the product card to delivery and payment.

I agree to start with an audit of 1-2 pages. Without written blockers, it makes no sense to proceed; the scope will drift, and we will both lose.

I work solo as a full-stack developer. In my production environment (auth, Stripe billing, AI chat), migrations, README, and .env.example have been in place since the first commit. Your requirements for the handover are standard for me, not a burden.

To proceed with the audit:
1. Where is the main blocker now: checkout, Carstore API, or Nova Poshta?
2. Will I get access to the repository and database before or after the audit?
3. Has the payment gateway already been chosen?

I am ready to take on the task.

Deadline: audit 1-2 days, then 8-10 days of work after agreeing on blockers.

Stages:
1. Audit of 1-2 pages + written list of blockers, 2000 UAH, payment upon completion
2. Integration of Carstore API + catalog + product card, 5400 UAH
3. Cart + checkout + Nova Poshta + online payment, 7200 UAH
4. Deployment + handover (Git, README, .env.example, migrations), 5400 UAH

Total: 20,000 UAH. Expand

Hello.
Regarding the project description and requirements for the development process. Working with Git, README, .env.example, migrations, deployment, and secure access transfer is standard practice for us, not an additional request.
The Next.js and PostgreSQL stack is part of our daily work. I have implemented SaaS projects with a codebase of over 100,000 lines on this stack, and I have significant production development experience. I am familiar with catalogs of auto parts and data models based on the principle of multiple compatibility between car/part, and I am ready to work through the specifics of the Carstore API during the audit phase.
Proposed workflow.
The first step is a mandatory audit of 1-2 pages. Document format: assessment of the current state of the codebase, description of working and non-working parts of the critical path from search to order placement, list of identified blockers, and a minimal action plan with prioritized tasks. The audit is paid separately from the main project and does not impose obligations for further cooperation. If the approach does not suit you based on the results, the document remains with you and can be used when working with another contractor.
The second step is to form a work plan by stages after agreeing on the audit. Each stage is documented with a description of input and output artifacts, acceptance criteria, and a clear result. The result is transferred via a pull request with a verification checklist.
The third step is to document blockers in writing through Notion or GitHub Issues. The principle of working with blockers: information about the problem that has arisen is provided within a day of its discovery, along with possible workarounds.
Regarding integrations. I have worked with Nova Poshta, and I understand the specifics of updating the branch directory and limitations on dimensions. I have experience with payment systems LiqPay and WayForPay, including integration with fiscal receipts, which is mandatory for the Ukrainian market. If the payment system is already defined, please indicate it in the discussion.
Regarding deployment. I am ready to integrate into the existing infrastructure or set it up from scratch based on VPS, Docker, and GitHub Actions for CI/CD. Access transfer is carried out through secure channels.
I am ready to start the audit at the agreed time.

Budget: 25000 UAH Deadline: 10 days

I understand the task - it is not to "finish the front," but to bring the product to a working state with a proper architecture and a complete user scenario.

I am currently working in this format — through an audit, identifying blockers, and phased implementation with responsibility for the result, not for "closed tasks."

Here’s how I propose to proceed:

First, an audit (1-2 pages, as you indicated)
I will analyze the current code
Check the architecture (Next.js + API + DB)
Identify bottlenecks and blockers
Provide a written list of issues + a solution plan

Then, in phases:

data catalog and structure
product card
cart and order logic
checkout
delivery integration (Nova Poshta)
online payment
deployment and infrastructure

Technically, I work with
Next.js
PostgreSQL
Node.js / API integration

What is essential for me (and aligns with your requirements):

Git + proper repository structure
README
.env.example
database migrations
deployment
final project handover

I document blockers in writing and work in phases, with clear results at each step.

An important point - most often in such projects, the problem is not in "writing more code," but in the incorrect linkage of API/data/cart logic. This is precisely what I address during the audit phase.

I am ready to start with the audit and then bring the project to a working state 👌 Expand

Hello,

I have solid experience with Next.js, PostgreSQL, API integrations, e-commerce architecture, deployment, and production handover. I understand that you are not looking for a simple front-end implementation, but for a contractor who can take responsibility for the final working product and overall user experience.

I can start with a structured audit covering architecture, current code quality, blockers, API integration status, database structure, security, deployment readiness, and scalability concerns. I work in stages with clear documentation and can provide proper Git workflow, README, environment setup, migrations, deployment process, and secure final handover.

I am also comfortable handling checkout flow, payment integration, Nova Poshta integration, catalog/product structure, and production optimization. Communication, transparency, and documenting blockers are part of my workflow.

I would be glad to review the current codebase, videos, and project history and discuss the next steps.

The video and project story are the right approach, so I will understand the current state faster. I looked at a similar case: a store on Next.js with a custom catalog, where the client complained about the build speed. I rewrote getStaticProps and API routes, and the loading time of the card dropped from 4 to 0.8 seconds. I also did the integration of Nova Poshta and online payments; usually, the biggest hassle is not the APIs themselves, but error handling and order states. I am ready to start with an audit of one or two pages and will immediately document the blockers in writing. One question: is the current code already deployed somewhere, or is this purely local development?

Budget: 19000 UAH Deadline: 25 days

Good day. I represent the Nexus Core team. Your request is clear to us: we need not just a performer to "polish the front," but a contractor who will take responsibility for the working result of the store on Next.js + Carstore API + PostgreSQL — with a mandatory audit of the current state, documentation of architectural problems, completion of the key user scenario, and proper final handover of the project. This is exactly the format we work in: first, a short technical audit of 1–2 pages analyzing the code, structure, blockers, and risks, after which we will sequentially close the catalog, product card, cart, checkout, integrations with Nova Poshta and online payments, deployment, and documentation. Since your current stack already matches our approach, we will not rewrite anything "for the sake of rewriting" — we will strengthen the architecture where it is truly needed and bring the project to a working state.

Regarding the stack, we propose to maintain and refine the current foundation: Next.js 14 / React / TypeScript, Node.js integration layer, PostgreSQL, API integrations with Carstore, payment and delivery, deployment via VPS + Docker or Vercel depending on the current architecture. We can conduct the audit as the first step for $300, with a timeframe of 2–3 days. After the audit, we will provide an exact estimate for the refinements, but the project estimate is in the range of $2,500–3,500 and 3–4 weeks, unless critical issues arise in the current code. We will immediately incorporate what is essential for you: Git, README, .env.example, migrations, written documentation of blockers, phased acceptance, deployment, and secure transfer of access. Cases are under NDA, but in private messages, we are ready to discuss similar projects on Next.js, PostgreSQL, and API integrations in detail.

To immediately clarify the actual scope, it is important to specify 3 points: what is the current state of the checkout and personal account, what specific online payment is planned — LiqPay, Fondy, or another provider, and is there already access to the current server / database / domain for a full audit not only of the code but also of the infrastructure. Write in private messages — we will clarify the details, start with the audit, and after that, we will provide a fixed estimate for the stages and timelines without vague promises.

The task is clear: bring the store to a turnkey working state — from code audit to deployment and access transfer. I work with Next.js, PostgreSQL, REST integrations; Git, .env.example, migrations, README — standard, not an option. Starting with an audit of 1–2 pages, I document blockers in writing, working in stages with intermediate demos. I have done integrations for Nova Poshta and online payments (LiqPay/Fondy) within similar e-commerce tasks. I am ready for 20,000 UAH with a clear scope.

Please send the current repo and video — I will assess the actual volume of work and clarify the stages?

Hello, I have extensive experience with this database, a project for a large company with roles, accounts, a project of about 2 million characters and 400 working files with code, a PostgreSQL database, the architecture of the project is very high quality, I can show everything. I will do everything quickly and efficiently. The deadline and cost depend on the project.

I see that the task involves refining the online store for auto parts using Next.js, Carstore API, and PostgreSQL. The main challenge lies in the integration with the API, setting up security, and deployment. Additionally, it is important to consider the project's architecture and user experience at all stages: from the catalog to online payment. I will focus on auditing the existing code and developing the architecture, ensuring reliable interaction between the store's components.

From a risk perspective, potential difficulties with integrating payment systems and implementing shipping through Nova Poshta should be taken into account, as well as the lack of documentation for the current code. It will be important to clearly document blockers and work stages. I have a few questions: are there ready-made mockups for the interface to clarify the design? Is there an understanding of the data security requirements? What is the overall plan for working on the project?

Considering the complexity and extensive nature of the work, I propose to complete the project in 7 days. The actual cost of the refinement will be 27,000 UAH, which reflects the necessary expenses for time and resources for quality execution. Let's discuss the details and get started quickly.
