CV
🚀 From zero to MVP, from prototype to scalable system.
I’m Yevhen — a React-focused full-stack developer with 6+ years of experience helping startups turn ideas into real products.
I build full-stack applications that are ready for production, easy to maintain, and built for growth.
Stack:
Frontend: React, Next.js (SEO, performance, responsive UI)
Backend: NestJS, Express (monoliths & microservices)
AI & Web3: OpenAI integrations, IPFS, ERC-20, DeFi flows
What you get:
- MVP in weeks, not months ⚡
- Clean architecture that won’t collapse on scale 🏗️
- Deep debugging & refactoring of messy codebases 🧩
- Product thinking, not just code
- Fast iteration and clear communication
Dashboards, AI features, Web3 infrastructure, internal tools — I build systems that work in the real world.
You bring the idea. I turn it into a working product.
