Software developer at JoyPix · open for the right opportunity Doha, Qatar

Firas Lamouchi — full-stack developer & systems architect

I'm the only developer on JoyPix's applications platform in Doha — three web apps, a mobile app, and the infrastructure behind them. Four years working alone taught me to find failures that don't announce themselves, like code that returns 200 and is still wrong. I write each one up below.

How I work

One place to enforce each rule. Deny by default. And I don't call something done until I've used it myself the way the real user would.

JoyPix — the platform, day to day

My actual job. Three web apps, a mobile app and the infrastructure under them, as the only developer on it. Live at eduqate.qa.

Ferry — heading for release

The peer-to-peer transfer daemon goes public. Eight Rust crates, a CLI, a VS Code extension and a desktop app, all talking to one local daemon. No server anywhere.
