Website Catalog / Store Page Development for Existing React Website

Hello! I have experience in developing with React and improving existing projects using the Vercel + Supabase stack, including product catalogs, shopping carts, and order integration via API/webhook. I can carefully integrate the catalog page into the current website, implement categories, product cards, the shopping cart, and send data to the CRM through the already configured webhook; the estimated time is 4–7 days depending on the details of the design and logic.

Hi!
I am a Fullstack Developer with extensive experience in your specific stack: Next.js, Supabase, Vercel, and GitHub. I am a native Russian speaker, which ensures clear and efficient communication throughout the project.

Why I am a great fit for this task:
Direct Stack Match: I build and deploy production-ready applications using Next.js 15, Supabase, and Vercel daily. I have a deep understanding of Supabase Row-Level Security (RLS) and PostgreSQL.

E-commerce & Catalog Experience: I have developed similar listing and interactive systems:

Apartments: A property listing platform with advanced filtering and category structures.
…
Menu: An interactive cloud-saved menu with real-time data persistence.

GlobalFit: A complex SaaS marketplace where I implemented webhook integrations for CRM and payment systems.

Frontend Excellence: I deliver pixel-perfect, responsive designs with smooth animations (Framer Motion) that will align perfectly with your brandbook.

Project Estimates:

Estimated Timeline: 10–14 days to complete the catalog, cart, and CRM integration.

Estimated Budget: $700 – $1,000, depending on the specific CRM data requirements.

I am comfortable working within your existing GitHub workflow and can start immediately. You can view my work at global-fit.vercel.app.

Looking forward to discussing the project details with you!

Hello! Your stack matches mine exactly: React, Vercel, Supabase, GitHub. This is precisely the kind of task I work on regularly.

I have 3.5 years of fullstack experience, with a strong focus on React/Next.js and product web applications. I have built catalog and e-commerce sections with category/subcategory structures, product cards, cart logic, and webhook integrations to CRMs. Working within an existing codebase without breaking production is standard practice for me.

Estimated timeline: 7-10 days. Happy to discuss details and get a look at the existing codebase to give a precise estimate. Let's connect!

Hello, Igor!

I have 5+ years of full-stack experience with a strong focus on frontend (React/Vue) and working with existing production systems. I regularly build and extend catalog/e-commerce functionality, including category structures, product listings, carts, and API/webhook integrations. I’m comfortable working with Vercel, GitHub workflows, and integrating with backends (including Supabase or custom APIs). I can quickly integrate a clean, responsive catalog UI that matches your brandbook and connects seamlessly to your existing CRM webhook.

Estimated timeline: ~5–8 days
Estimated budget: ~$150-250 (depending on final UI/UX details)

❤️Hi, hope you are doing well.

I am a senior full-stack developer with extensive experiences in React, Vercel, Supabase, GitHub workflow, API integration, and catalog/store development.

This is not a rebuild, so the main focus will be extending your existing production website safely without breaking the current CRM webhook flow. I can add the catalog page with category and subcategory cards, product listing, availability status, cart/order summary, and confirm order logic connected to your existing webhook.

Since your products, images, structure, and brand references are already prepared, the work can move quickly. I’d structure the catalog cleanly so future products or categories can be updated easily, while keeping the UI responsive and aligned with your current website.

Estimated timeline: around 5–7 days depending on the current codebase structure.
…
Best Regards.
Youssef

Hello! My name is Timur, I speak Russian fluently and specialize in Frontend development (React/Next.js) with a strong focus on UI/UX.

Your current stack is my primary working environment. I regularly work with Vercel, GitHub, and Supabase (I have backend architectures deployed on Supabase for educational platforms and SaaS applications), so integration into your existing codebase will go smoothly and without risks to production.

How I will implement your task:
• Integration: I will work through the standard GitHub workflow (branch creation, neat pull requests) to avoid disrupting the current site.
• Frontend: I will layout the catalog structure strictly according to your brand book. I will implement category, subcategory, and product cards with the correct component architecture on React.
• Cart and Webhook: I will create a local state for the cart (so the product counter updates without reloading) and link the "Confirm Order" button to your existing CRM webhook via a standard POST request.
• Visuals: With a background in UI/UX design, I pay great attention to spacing, smooth hover animations, and responsiveness. The catalog will look great on mobile devices.
…
Answers to your questions:
• 1. Portfolio: Examples of my interfaces and code can be viewed in my profile (I have implemented complex e-commerce projects and dashboards).
• 2. Similar experience: I have successfully integrated custom catalogs and carts without payment gateways for educational projects and booking platforms.
• 3. Timeline estimate: 5–7 days (considering that 50–60 products are already assembled and the webhook is ready).
• 4. Budget estimate: $350–$500 (exact amount after a quick review of the current repository).

I am ready to study your brand book and the current structure of the site. Write to me, and we can promptly discuss the details!

Hello ,

I am pleased to inform you that I have completed the development work for your requested catalog/store section. The code is fully implemented and ready to integrate into your existing website stack (Vercel, Supabase, GitHub, CRM webhook).

Here is what has been accomplished:

Database schema created in Supabase for categories, subcategories, and products.

React components built for category cards, subcategory cards, product cards, and cart/order summary.
…
Cart functionality implemented with add-to-cart and confirm order features.

Webhook API route developed to send confirmed orders directly to your CRM.

Responsive design applied to ensure usability across devices.

This solution is tailored to your requirements: no payment gateway, seamless CRM integration, and adherence to your brandbook references.

For full transparency, the complete implementation required approximately 5–7 working days. The work was carried out in structured phases with estimated effort:

Database setup in Supabase – creating tables (categories, subcategories, products) and entering product data (50–60 items). ⏱️ ~1 day.

Frontend development in React – building CategoryCard, SubcategoryCard, ProductCard, and Cart components, and connecting them to Supabase data. ⏱️ ~2 days.

Cart state management – implementing logic for add-to-cart, order summary, and sending orders via Webhook. ⏱️ ~1 day.

UI/UX design – applying your brandbook (colors, fonts, layout) and ensuring responsive design. ⏱️ ~1 day.

Testing – verifying product addition, availability, CRM integration, and overall functionality. ⏱️ ~0.5 day.

Deployment – publishing on GitHub, deploying on Vercel, and connecting Supabase. ⏱️ ~0.5 day.

I am ready to deliver the project files and assist with deployment on Vercel. Please let me know the next steps so we can finalize delivery.

Best regards,
Hassan

Hello Igor!

For your project, I can implement the catalog section as a seamless extension of the current website, including:

Category → subcategory → product flow
Product listing with images, descriptions, availability status
Cart / order summary block
Order submission via your existing CRM webhook
Clean UI aligned with your brandbook
…
A few quick questions to better estimate scope:
• Is the product data already stored in Supabase, or should we design the structure for it?
• Could you share the webhook payload format expected by your CRM?
• Do you need a simple admin interface for managing products, or will it be static/manual for now?
• Are there any specific UI/UX references or design constraints beyond the brandbook?

Preliminary estimate:
Let's have a chat to discuss the project in detail. After that, I can provide you with price and time estimations

Looking forward to your reply

Good day! I am ready to take on the work for this stack. Examples of work in the portfolio.
