I build systems that stay calm under load.

subject dossier

I design and ship backend-heavy systems where correctness and latency both matter.

I care about the unglamorous parts — schemas, failure modes, and the observability that tells you the truth at 3am.

// current focus

Currently focused on realtime infrastructure and developer tooling. The skills behind this work are charted live in the constellation at origin — each project pulls from the systems it was built on.

A short catalog. Depth over count.

Each plate is a system I designed and shipped end to end. Steer through them — the skills behind each one are charted back at origin.
