01.about

Senior engineer with 10+ years shipping production software in TypeScript, Node.js and PostgreSQL. Lately my focus has been building AI agents that handle real work end to end, wired into the tools and data a business already uses. With AI in the loop I ramp up fast on any new stack; what never changes is the fundamentals: clean design, tests and code that's easy to maintain.

I work closely with non-technical teams to find where agents save time or money, then build, deploy and monitor them. I use Claude daily: through its API to build agents, and in my own engineering workflow via Claude Code and OpenCode.
