About Me

Driven by Curiosity, Built for Security & Scale

Bridging engineering rigour with intuitive, human-centered digital experiences.

Background & Academic Track

I am a Computer Science student at Batna 2 University (Mostefa Ben Boulaïd), specializing in Information Security. My passion lies at the intersection of modern software development, robust web security, and high-performance system architecture.

Over the past 3+ years, I have engineered full-stack platforms ranging from nationwide environmental GIS telemetry dashboards to SaaS dental clinic management software and AI-powered e-commerce trust scoring engines.

Strong foundation in algorithms, cryptography, and network security protocols.
Hands-on production experience with React, Node.js, Express, REST APIs & WebSockets.
Active contributor to developer communities, hackathons, and GDG DevFest events.

Security-First Mindset

I build software with security integrated at inception — implementing zero-trust principles, sanitized API boundaries, robust JWT/OAuth authorization, and continuous threat mitigation.
