About me

Junior developer, final-year CS student — I ship real systems and I'm ready to join a team

I'm a Junior Full-Stack Developer and final-year Computer Science student at MLA, Tel Aviv. I'm actively looking for my first full-time developer role — junior positions where I can contribute from day one, learn fast, and grow alongside a strong engineering team.

Before software, I served as a fighter and special means operator in the IDF's elite YAHALOM Special Operations Engineering Unit — leading operational activities in high-pressure, classified missions. That experience gave me discipline under pressure, fast decision-making, and the ability to execute complex plans end-to-end.

When I'm not coding or studying, I'm playing water polo, playing guitar, or DJing. I built a full-stack desktop app for DJs — which is what happens when you write code about things you actually care about.
