About

I build full-stack applications and web3 infrastructure — from frontend UIs to blockchain APIs, mobile apps to validator nodes. My workflow spans TypeScript, Next.js, Solana (web3.js, Anchor, SPL tokens), FastAPI, Flutter, and Docker. I ship production software that serves real users and maintain decentralized systems that run 24/7.
