Hello! My name is Artur, and I represent the Alfateam development team. I carefully studied your technical assignment for creating a demo version of a cryptocurrency wallet. We have extensive experience working with React.js/Next.js, Node.js/Express, and Laravel, as well as with PostgreSQL/MySQL databases. We have already successfully implemented projects requiring integration with external APIs (for example, CoinGecko).

Our approach to solving your task will be as follows: developing an interactive frontend on React/Next.js using Tailwind CSS for styling, creating a backend on Node.js/Express or Laravel for data processing and user management, setting up PostgreSQL/MySQL databases for storing information. Special attention will be paid to security (bcrypt password hashing) and creating a user-friendly admin panel for managing balances, transactions, and exchange rates. It is also important to develop a sales website for further promotion via Yandex Direct (considering the need for a convenient administration system).

I suggest a call for a more detailed discussion of the requirements and clarification of deadlines. I am confident we can create a quality solution that will meet your expectations.

Good day!

My name is Ruslan, I am a senior full-stack developer with practical experience in creating scalable web applications, particularly in FinTech and Web3 sectors. I am interested in implementing your technical task for developing a demo version of a cryptocurrency wallet.

🔧 Why I am a strong candidate for this project:

1. Technical expertise:
• Frontend: Next.js + TailwindCSS — I work with them daily, well-versed in SSR, API Routes, performance optimization.
• Backend: I work with Node.js (Express/Nest) at production level. I also have experience with Laravel, but the priority is Node.js.
• Database: Confident in working with PostgreSQL (relational structure, transactions, query optimization).
• Security: bcrypt for hashing, rate limiting, auth via JWT/cookies, access rights restrictions.
• DevOps: setting up and deploying on VPS with HTTPS (NGINX + PM2), configuring CI/CD.

2. Domain understanding:
• Seed phrase generation (12-word mnemonic) — implemented via bip39 (offline).
• Simulation of multi-currency wallet — implemented through custom balance modules, without real blockchain integration.
• Currency rates — integration with CoinGecko API with backend caching.

3. Architectural approach:
• The entire app will be built as an SPA with SSR (for SEO) and CSR after login.
• Login/registration page, seed generation with mandatory confirmation.
• User roles (user / admin) + access middleware.
• Admin panel with analytics (charts via Chart.js or Recharts).

⸻

🕓 Timeline:

Approximately 3–4 weeks for MVP implementation with testing.

💰 Budget:

I estimate the scope of work within your budget — $10,000. Ready to work on a phased basis (reports + repository access).

⸻

I am ready to show a portfolio, GitHub repositories, as well as cases of similar implementations (especially in finance, dashboards, admin panels).
If necessary, I am willing to involve additional developers to speed up development.

I would be glad to discuss the details of cooperation.

Best regards,
Ruslan Zocenko Expand

Hello!

I see that you are looking for a developer for a demo version of a cryptocurrency wallet. I have experience with similar projects - I worked on a platform where transactions between users were implemented on a conditional exchange. I was responsible for architecture, exchange logic, optimization of large SQL queries, and more.

For your project, I suggest using FastAPI - it is fast, convenient, and productive (asynchronous operation, automatic documentation, easy data validation via Pydantic).

I can implement the frontend using Next.js + Tailwind, and PostgreSQL would be suitable for the database. Hosting on a VPS with HTTPS is also not a problem - I have set it up multiple times using Docker + Nginx.

I work with the full development cycle: authorization, personal account, API connections, analytics. In projects, I adhere to simplicity, logical structure, and stability.

We can discuss the details and break down the implementation step by step. Expand

Hello!
Our experienced team, consisting of highly qualified backend Java/Spring developers, frontend React/Next.js specialists, and a professional UI/UX designer, is ready to undertake the development of this project.
We understand your goals and technical requirements. For the frontend, we will use React.js/Next.js combined with Tailwind CSS to create a modern, intuitive, and visually appealing interface that will accurately mimic the operation of a real wallet, as well as ensure excellent responsiveness.
Regarding the backend, our core stack of Java/Spring Boot is an extremely reliable, scalable, and secure solution, ideally suited for developing APIs and logic. We also have extensive experience working with PostgreSQL as the database, as well as setting up hosting with HTTPS and password hashing using bcrypt to ensure security.
We are confident that our experience in creating complex web applications, including data management systems and integrations, will allow us to develop a high-quality demo version of the wallet.
We would be happy to discuss the project in detail and showcase our portfolio.
