Senior product engineer with 10+ years of frontend focus — React, TypeScript, Next.js, and the full product layer above the API. I care as much about what gets built as how it's built, and I can go deep on the backend when it matters.

Product-minded.
Frontend-first.

Frontend & Product

Pixel-perfect interfaces with real product thinking behind them. I own the full user-facing layer — architecture, state, performance, and the details that make users love what they're using.

Backend

Enough to own a feature end-to-end. APIs, databases, and the data layer — I don't hand things off and wait; I build what the product needs.

Node.js Python PostgreSQL Supabase
📱

Mobile

Apps that feel native because they are. Cross-platform when it makes sense, native when it doesn't. Your users can't tell the difference.

AI Integration

Not just prompt wrappers. Real AI-native products — intelligent workflows, RAG pipelines, and agents that do actual meaningful work.
