I’m a junior full-stack .NET developer from Algeria, focused on building secure systems by default—especially around authorization, auditing, and reducing failure modes before they become incidents. I’ve shipped production work and experiments across ASP.NET Core APIs, JWT-based authentication, and desktop/mobile clients (WPF and .NET MAUI), with a strong bias toward deny-by-default access control and layered security. My recent security-driven project, ArchiShield DZ, is centered on preventing data leakage by design: server-side rendering keeps raw source files off the client entirely, and the platform uses per-viewer watermarking plus an append-only activity log for compliance and traceability. I’m also CCNA-certified, comfortable with networking fundamentals, and I enjoy building systems where the security model is enforced consistently across every access path.
