I'm a backend and platform engineer with more than 20 years of experience building systems that need to stay up and stay fast.
A calm SSL certificate monitor that emails you before your certificates expire, and quietly keeps an eye on whether your sites are responding while it's at it.
Agent driven backend for your own Kubernetes. Deploy, roll back, scale, and maintain your app through agents like Claude Code with guardrails so your agent doesn't break prod.
S3 compatible object storage in a single binary, with erasure coded durability, versioning, and object lock built in.
Go, Postgres, and the unglamorous infrastructure that keeps products running: queues, schedulers, data integrity, and reliability. I like simple architectures that are easy to reason about and hard to break.
