/about

It's me

I'm a backend-leaning full-stack engineer currently working as CTO at Nexcentia, where I design scalable backend systems and manage the cloud infrastructure that keeps them running. Before that I spent a few years across product teams building Django and Go services, real-time systems, and the odd cross-platform desktop app — plus two years freelancing, solving business-specific problems for clients directly.

Outside of work I like understanding things from the socket up — that's what led me to build Cerveur, a custom HTTP server written in raw C, just to see how much of "the framework" I could build myself. Right now I'm going deeper intosystem design — studying and implementing the patterns behind systems that actually hold up at scale.
