Engineering Philosophy
"Good software isn't just about making things work — it's about making them work reliably, securely, and in a way the next engineer can understand."
My current focus is on fintech systems, serverless microservices, and real-time communication platforms. I care about clean API design and payment infrastructure users can trust.
When I'm not coding, I explore system design concepts and contribute to making that knowledge accessible to the Bangladeshi developer community.
