About

01 / Profile

I build the unglamorous parts of software — the queues, the workers, the pipelines, the deploys — so the rest of the product can move quickly without falling over.

My record spans streaming, learning, logistics, payments, marketplaces, and internal tools — improving system performance, scaling data pipelines, and delivering platforms that hold up in production.

I care about clean APIs, predictable failure modes, observability you can actually debug from, and infrastructure that doesn't surprise you at 3am.
