Shahadath Hossen Sajib
Backend Developer · Creator of Systemix
About
I'm a backend developer who enjoys building things that work well and scale. I spend most of my time with Node.js, NestJS, and Express, designing APIs and systems that are secure and maintainable.
Systemix is a side project — a small toolkit for cryptographically secure utilities like password generation, passphrases, and token signing. The goal is to provide minimal, well-tested primitives you can drop into any project without pulling in unnecessary dependencies.
Writing
I write about backend engineering, system design, DevOps, and real-world project learnings.
“Clean architecture, clear intent, and systems that scale. ”
