Backend Software Engineer | Distributed Systems & DevOps Enthusiast
📍 Dhaka, Bangladesh | 🔧 Go • Dart • Python
I'm a software engineer with almost 3 years of experience building backend systems and distributed architectures. I enjoy working on problems that require digging deep—whether it's optimizing database queries, designing microservices that can handle real traffic, or figuring out why a system behaves the way it does.
Most of my recent work involves Go, but I've also spent time with Flutter when mobile development was needed. I like learning new technologies when the problem calls for it, though I find myself most energized when I can understand not just how to use a tool, but how it actually works underneath.
When I'm not coding, I'm probably reading about system design, working through algorithm problems, or reading through open-source project architectures on DeepWiki that help me stay sharp and learn how experienced engineers solve complex problems.
