Building

I build product systems, not isolated pages — applications with real users, permissions, workflows, data, integrations, and operational constraints.

My default environment is TypeScript / Next.js / PostgreSQL.
When the backend deserves its own weight, I reach for Java / Spring Boot.

Recently, I've been especially interested in AI-native workflows, automation, search, authorization, and systems that coordinate multiple actors cleanly.

Defaults

Next.js TypeScript React PostgreSQL Java Spring Boot

Engineering notes

  • Make state explicit. Hidden state becomes production bugs.
  • Authorization is domain logic. “Logged in” is not the same as “allowed.”
  • Prefer boring foundations. Complexity should solve a real constraint.
  • Design for change. Good boundaries make the next feature cheaper.
  • AI has to earn its place. If it doesn't remove work or improve a decision, it is noise.

This GitHub

You'll mostly find experiments and product work around full-stack systems, backend architecture, automation, and applied AI.

Some projects are public. Others are client, academic, or product work and stay private.
