I build deterministic systems at scale, and now the systems that deploy and contain the non-deterministic ones.

I'm a senior software engineer at MoonPay, based in Lisbon. For years I have built deterministic systems at scale: payments and high-load distributed backends, where being correct under load is the whole job.

I am now working at the intersection of systems and ML, the engineering of deployed intelligence: making models reliable, fast, and cheap in production. This site is where I build in public. The models here run live, in your browser, next to the writeups and notebooks that produced them.
