About Seddik
I’m a full-stack developer who enjoys turning complex problems into simple, reliable solutions.
I work mainly with Java (Spring Boot) and Angular, building web applications that are both efficient and easy to maintain. I care a lot about clean code, good structure, and making sure everything works smoothly—not just on the surface.
I’m the kind of developer who digs into issues, understands the root cause, and fixes things properly instead of applying quick patches.
If you need someone dependable who communicates clearly and gets the job done right, I’d be happy to work with you.
