About
I'm a Full-Stack AI Engineer with 8 years shipping production systems across e-commerce, Web3, and applied AI.
- I build conversational AI that holds up under real traffic: RAG pipelines, agentic workflows, and support platforms that resolve 70%+ of tickets without a human stepping in.
- Deep Medusa.js experience (v1 and v2) on the commerce side, from zero-downtime migrations to multi-vendor marketplaces and semantic product search.
- In Web3 I've shipped NFT minting infrastructure, smart-contract launchpads, and DeFi dashboards, including ApeBoard (acquired by Nansen).
- Mostly backend (Python, FastAPI, Node.js), but happy owning the frontend in Next.js and Tailwind. Claude Code, Cursor, and Codex are part of my daily workflow.
