About Me

Ziyad El Abid

I'm Ziyad El Abid, a full-stack software engineer based in Casablanca, Morocco. I've spent nearly four years at Theodo Maroc, mostly working with Java / Spring Boot on the backend and React / Next.js (TypeScript) on the frontend.

What drives me is making the product genuinely better — faster queries, tighter security, smoother user flows — and doing it with quality that lasts: well-tested code, honest reviews, and clean architecture. I've also had two open source pull requests merged intoSentryand Jest, and I enjoy helping junior developers get up to speed.
