MD OLIULLAH SARDER

Software Developer

Building web systems · exploring how software works underneath




01 — About

I'm a Software Developer with 3+ years of professional experience building full-stack applications, backend services, and production systems.

I’m a self-taught developer who likes to understand what happens underneath the abstractions I use — from how code is processed and executed to how applications communicate with databases, servers, and other services.

I build things to learn, solve problems, and understand systems better.
