I work at Emerson on the web platform behind grid-monitoring software that utilities use to run the electric grid.

Most of my work is access control. I design and build the services and REST APIs that decide who can see and do what, along with the data models and migrations behind them.

I set up the application’s first unit and integration test framework, which now runs several hundred tests. I also work on performance and dependency security when needed.

I work daily with AI coding agents: Claude Code, OpenAI Codex, GitHub Copilot and T3 Code. Outside work I build full-stack projects in TypeScript, Next.js, Flutter and Firebase.

Projects

I build these outside work. The source for both is private, so this page is where I show them.
