Send To - Chrome extension

About

A bit more about me

Hey 👋

I'm Hossain. A software engineering degree at ENSA, a MIAGE Master's at Polytech Lyon - and above all a lot of code shipped to real clients: first as a freelancer, then at Oracle and Novelis, and these days Spring Boot and Angular at Atos, on business-critical applications for the Enedis IT division.

What I genuinely enjoy building is clean back ends: an API whose contract reads for itself, tests that actually earn their keep, a deployment that stays up without anyone poking at it.

The rest of the time I self-host my own work - every site listed above runs in a container behind my own Traefik. The "Send To" Chrome extension came out of a very concrete frustration: being tired of bouncing between tabs just to look up three words.
