About me
From database research to quantum computers.
I’m a software engineer in Paris. I received my PhD in Computer Science from Université Grenoble Alpes in 2021, then worked at Opensee before joining C12 in May 2025.
My interests include databases, distributed systems, queuing systems, and quantum computing. Outside work, I'm building anything, mostly native apps for iOS and Mac recently.
