DESCRIPTION

I'm a software engineer from Lisbon. I've spent the last decade shipping products — from telco testing rigs to property software to onchain identity.

My sweet spot is the middle of the stack: fast feedback loops, thoughtful APIs, tidy React on top. I care about the small choices that compound into something that feels good to use.
