Zobayer Alam | Software Engineer & Security Enthusiast

About Me

I am a Software Engineer dedicated to building high-performance applications that are secure by design. While my professional focus is on engineering modern software solutions, I remain a deeply active hobbyist in cybersecurity and network architecture, constantly exploring the intersections of code and infrastructure.

Currently based in Dhaka, my toolkit centers on modern stacks like Next.js, NestJS, and TypeScript, integrated with a DevSecOps mindset. I enjoy experimenting with containerization (Docker/Kubernetes) and automated deployment pipelines, always layering in networking fundamentals and security hardening to ensure every project is resilient against modern threats.
