Redesign of the fintech platform (Node.js + React) + further support

Good day!
I have experience working with Node.js and React, including with SaaS/fintech interfaces, personal accounts, admin panels, and redesigning already functioning products without breaking business logic.
I can connect to your platform, completely update the UI in a dark theme in the style of Web3/crypto/financial minimalism, integrate the new design into the current system, and maintain the correct operation of balances, accruals, and all existing logic. I can also tidy up the admin panel and lay a solid foundation for further improvements.
I work well with other people's code, can independently make technical decisions, and engage not only in redesign but also in the further development of the product.
I am interested in long-term cooperation. I am ready to discuss the details in private messages.

Hello, my last similar project - https://agnthub.ai/ - is a Web3 platform for creating and managing artificial intelligence agents, where we worked on the product's UX, dashboard flows, and blockchain-oriented functionality, and I would like to help you redesign your fintech platform and integrate a new user interface into the existing logic. Please review my other relevant projects below 👇

Web3 / fintech projects:
https://x.com/buildonhybrid/
- Hybrid, a second-layer ecosystem based on Ethereum with a complex interface and Web3 product infrastructure

https://x.com/tenet_org/
- TENET, a first-layer DeFi ecosystem with a wallet, dashboard, and financial product flows

… https://x.com/raiser_co/
- Raiser, a premium launch platform for first-level crypto projects with user-oriented and admin-side functionality

Send me what you already have, I would like to review the current frontend, admin panel, and structure before we begin.

Feel free to reach out to me, and let's make this happen!

Best regards,
Vyacheslav

Hello,

I have reviewed the assignment and I see a project with a specific structure and functioning logic — this is a good starting point for a professional redesign.

My experience in Node.js, React, and redesigns of SaaS and fintech platforms allows me to smoothly engage with the existing code without unnecessary risk and chaos. I know how to maintain stable business logic while completely refreshing the interface — dark theme, Web3/crypto style, modern financial minimalism.

Cost estimate for the redesign (landing + user panel + admin panel + backend integration):

6,500 – 9,000 PLN net, completion time: 3–4 weeks
…
I work iteratively — first, mockups of key views for approval, then implementation while preserving all current logic. Zero surprises halfway through.

You can see completed projects at soft-synergy.com/portfolio — you will find thematically similar examples there.

If you are looking for someone for long-term cooperation in developing the platform, this type of work suits me best — I prefer to build a relationship rather than carry out one-off assignments.

I would be happy to schedule a short online meeting — this is not just a preliminary conversation, but a specific technical consultation, after which you will receive a detailed report and a binding offer.

Hello,

I have reviewed the assignment and I see a project with a specific scope and real potential for long-term collaboration — exactly the type of assignments I enjoy working on.

Redesigning a fintech platform in a Web3/dark theme is something that requires not only skilled hands for coding but also a sense of financial product. I have experience both in working with existing Node.js + React projects and in building interfaces that look like a premium-class product — not like a template.

The cost for the redesign (one-time): 8,000 - 12,000 PLN net, depending on the details of the scope and approach (custom UI vs. template adaptation).
Completion time: 3-4 weeks.

… Further technical support I estimate as a long-term collaboration in an hourly model — 100 PLN/h net, with the possibility of establishing a monthly subscription after the first stage.

I work directly with the client's code — without rewriting what works. Integrating the new design with existing logic is standard in my projects, not a challenge.

You can see selected realizations here: https://soft-synergy.com/portfolio

I would be happy to schedule a short online meeting — it's a good opportunity to discuss the details with our specialist, and after the conversation, you will receive a detailed report and a binding offer.

Hello!

I am a Full-Stack Software Engineer with over 7 years of experience in developing websites, SaaS solutions, complex web platforms, and MVPs for startups - from idea and architecture to production and support.

I work not only as a developer but also with a focus on business logic, scalability, and long-term support of solutions. My portfolio includes examples of implemented projects of varying complexity.

Technology stack:
PHP (Laravel, Symfony, Yii2),
Frontend: JavaScript (Vue.js, React.js), HTML5, CSS3,
… Databases: MySQL, PostgreSQL.

Regarding timelines and costs - at this stage, it is difficult to accurately assess them without clarifying the requirements. To form a reasonable estimate, it is usually necessary to understand:
- the goals of the project;
- key functionality;
- expected load and integrations;
- priorities (quick launch vs scaling).

I suggest starting with a brief clarification of requirements or a call/email - after that, I will be able to provide a realistic estimate on timelines, budget, and implementation options.

I would be happy to discuss the details.

Hello! I read your description — this is 100% my profile. I am a Full-stack developer (React / Node.js) and I specialize in such dashboards and SaaS platforms.
I will immediately share my opinion regarding templates: since you already have a ready and working logic on React, applying a purchased template there is a pain and a bunch of crutches. They often bring a lot of unnecessary code that will conflict with your states.
It is much cleaner and more correct to build a new UI from scratch using Tailwind CSS. This will provide the same Web3 / Crypto minimalism, an ideal Dark Theme, and most importantly — we will carefully transfer your existing business logic without breaking the connection to the backend.
Since I write in Node.js myself, I won't need to be explained how your APIs work. I will easily understand someone else's code, connect new components to existing endpoints, and display all balances and accruals.
Here are my projects where I did both front-end and back-end, and complex custom admin panels:
• Holy Drip (holydrip.com.ua) — a platform with its own custom admin panel, user management, statuses, and analytics.
• NMP Interior (nmpinterior.co.uk) — development of a platform with its own content management system from scratch.
• My Best Song Gift (mybestsonggift.com) — a service with custom user state logic and payment integration.
Regarding long-term cooperation — this is exactly what I am looking for. I am interested not just in "repainting" buttons, but in further developing the product, implementing new features, and optimizing the backend.

Hello!

I looked at the description — it's an interesting project. My stack: Node.js on the backend, React on the frontend, I work with this combination constantly.

What I like is that the platform is already operational, meaning there is a foundation to build upon. From experience, I know that in such projects, the main thing is to first understand what has already been written, rather than rushing to rewrite everything from scratch. Usually, I start with a code audit: I look at the structure, dependencies, where everything is connected, and only then do I plan the redesign.

On the frontend, I will create a proper component structure, make it responsive, and tidy up the UI. On the backend, if something needs to be refactored or added, I am also ready. I have no problems with support afterwards; I even find it more convenient to work long-term than on a one-time basis.

Please send the layouts or at least screenshots of the current state — I will be able to give a more specific estimate on timelines and costs.
…
Thank you!

Hi,

I can handle the complete redesign of your fintech platform and long-term cooperation. I have experience with Node.js and React full-stack development, redesigning SaaS platforms, and working with existing codebases.

I will create a modern Web3/crypto style UI with dark theme and financial minimalism aesthetic, integrate the new design with your existing Node.js backend preserving all business logic for balances, accruals, and user management, update the admin panel with improved UI and usability, and ensure the platform looks like a completely new product while maintaining functional stability.

I recommend purchasing a quality React template (like from ThemeForest or similar) with Web3/crypto aesthetic and adapting it to your existing backend. This approach saves development time while ensuring professional design quality. Alternatively I can create custom design from scratch if you prefer full uniqueness.

I am comfortable working with existing code and making independent technical decisions. I am interested in long-term cooperation for enhancements, new modules, support, and optimization after redesign completion.

Hello!

Thank you for the detailed project description. I have experience with similar tasks and am ready to take on the redesign of your fintech platform.

## My Experience

**Full-stack development:** 7+ years of commercial experience
**Backend:** Node.js, PHP/Laravel, REST API, payment system integrations
**Frontend:** React, Next.js, modern JavaScript
… **Projects:** Development and support of SaaS platforms, e-commerce, integrations with financial APIs

## How I See the Implementation

### 1. Redesign (2-3 weeks)
- Analysis of the current code structure and business logic
- Selection and adaptation of a premium template (React + dark theme) or development from scratch depending on the specifics
- Creation of a component architecture in the style of Web3/crypto
- Integration with the current Node.js backend

### 2. Integration and Testing (1-1.5 weeks)
- Connection to existing API endpoints
- Correct display of balances and accruals
- Update of the admin panel with improved UX
- Testing on various devices and browsers

### 3. Documentation and Handover
- Description of the structure of the new code
- Recommendations for scaling
- Smooth deployment to production

## Template vs. From Scratch Proposal

I recommend **selecting a quality React template** with a crypto/fintech design:
- ✅ 30-40% faster
- ✅ Tested components
- ✅ Responsive out of the box
- ✅ More time for business logic

I can provide 2-3 template options for selection before starting.

## Collaboration Format

**Start:** Fixed payment for redesign
**Next:** Hourly rate or fixed sprints for refinements

I work with project management tools (Notion/Trello), daily updates, code reviews, Git flow.

## Next Steps

If the format suits you:
1. Send access to the demo/staging environment for scope assessment
2. We will discuss the budget and timelines

I am ready to answer any questions and discuss the details.

Best regards,
Roman
