About me
Full-Stack Engineer specialized in blockchain, Web Applications, AI-powered applications, and workflow automation. I build complete products end-to-end, from smart contracts and Web3 backends to SaaS platforms, Web Applications, LLM integrations, and n8n automations.
With 4+ years of professional experience, I've shipped production systems for international clients including a multi-tenant AI SaaS platform, NFT game backends, real-time multiplayer apps, and fractional ownership dApps.
I work async across time zones, communicate clearly, and deliver work that's built to last, not just to demo.

A pleasure to work with. Great communication, deep involvement, he proposed features we didn't ask for and took the time to explain in great detail the options everytime there was a choice to do. We will work together again, for sure!
