About
From writing code to redesigning how product teams work
I started as a software engineer. My first product job was at SpotYet, a startup I co-founded, where we took two SaaS products from zero to real customers. I wrote the matching algorithm behind both, and it doubled as my Master's thesis.
Then nearly five years at Amazon, running programs across nine European marketplaces. That's where I learned how a process change plays out at scale. One mechanism I launched cut 9 million customer contacts a year.
Since 2023 I've been co-founder of Product Circle, formerly Product Weekend, where we run small events for product builders and product leaders in 16 countries. At GaiaLogic I'm building Gaia Decision Intelligence from its first version. I work in English, Romanian and Italian.
