I build self-hosted tools for developers.

Payments platform engineer in fintech by day. Nights and weekends I build and sell tools I use myself: personal finance without bank logins, AWS security you can run in your own account, and the operating discipline for fleets of AI coding agents.

About

I run everything I sell: the finance app tracks my household, the security digest watches my own AWS account, and the agent-fleet playbook is how my repos actually ship. At home there's an over-engineered network with ADRs and runbooks, because a homelab deserves the same discipline as production. More about me →
