Hello, I'm Hamdan
I'm a backend Developer and Security Engineer focused on building secure, scalable software - from CI/CD pipelines to production-ready web apps. I build modern applications with NestJS, Next.js, Laravel, and PostgreSQL, and harden them with automated security scanning and DevSecOps practices. My security work covers static analysis and dependency scanning (Semgrep, Trivy), API threat modeling, vulnerability management, and secure SDLC pipelines. On the infrastructure side, I work with Docker, Kubernetes, Jenkins, and Nginx to ship and operate reliable systems.
