About

I'm Omar Zandag, a Bachelor's graduate in Computer Systems Engineering (ESTSB, Sidi Bennour), building on a DUT from ESTG Guelmim. Through my internship at Titrit Technologies in Casablanca, I refactored the backend architecture of an enterprise cloud tokenization platform — modernizing React.js interfaces and optimizing PostgreSQL performance.

I focus on backend development, software architecture, and cybersecurity best practices, and I work well in Agile teams. I speak Arabic natively and English and French conversationally.
