Summary

Fullstack & blockchain engineer delivering end-to-end products across DeFi, FinTech, and MedTech. Deep knowledge in Web3 applications, Solidity smart contracts, and non-custodial wallets, combined with strong skills in frontend (React/Next.js, Vue/Nuxt) and backend (Node.js, NestJS, Python) development.

I have successfully built MVPs, scaled platforms, and led technical teams, covering the entire lifecycle: from architecture design and implementation to deployment and DevOps. I thrive in environments where I can combine blockchain engineering with modern fullstack product development.
