I've been building things with computers since I was 12 — got my first machine and never looked back. Over two decades in tech, I've gone from curious kid to someone who architects systems that people depend on daily.


Currently I'm shaping healthcare technology at Aava, where I design and build the digital infrastructure that connects patients with care. I think about systems at every level — from the code that runs to the cloud it runs on, from developer experience to production reliability.


I'm the kind of engineer who automates everything, takes ownership of hard problems, and believes the best code is the code you don't have to think about twice. I thrive in teams that move fast, adapt to change, and care about craft.

Build & architect

Full systems from ground up — cloud infrastructure, APIs, frontends, pipelines. If it needs to exist, I'll make it exist.

Ship & operate

Production-grade systems that stay up. I care about what happens after deploy as much as before.

Solve & simplify

Legacy systems, complex migrations, gnarly bugs — I'm not afraid of the hard stuff. Usually that's where the interesting work is.
