software engineer · distributed systems & ML infra · currently at Imubit

Most machine learning outputs are predictions someone reads. I work on the kind that moves physical equipment – at Imubit, I build the on-prem application and cloud platform around deep-learning controllers that run refineries in closed loop.

I enjoy building predictable and reliable systems in the first place. Over the past year, I've also been contributing to open source, which you can check out on this page. I write here about whatever piques my engineering curiosity, problems I've run into, and what I learned solving them.

I'm always happy to hear from people working on distributed systems, ML infra, dev tools, or inference.
