Backend-first.
Shipped end‑to‑end.

I build secure, layered architectures — from hardened APIs and access-control gateways to full product platforms. I care about clean contracts, predictable state, and code that a future engineer can reason about without needing a guide.

Over the years I’ve shipped monitoring infrastructure, real-time event systems, preservation networks, and emergency alert platforms — each one production-ready from day one.
