01 / About Me

The engineer behind the code

I'm a full-stack software engineer based in Dhaka, Bangladesh, specializing in the .NET / ASP.NET Core ecosystem. Over the past 3+ years I've been the sole developer of record for 10+ corporate and institutional clients — owning everything from requirements gathering and system design to deployment and live production support.

My work spans ASP.NET Core/MVC platforms, Blazor and WPF desktop tools, and Python utilities that handle real financial transactions, workforce attendance, and industrial hardware operations. I've modernized legacy .NET systems into containerized, maintainable architectures, and integrated third-party hardware — biometric access control, RFID, and POS devices — into unified software platforms used daily by real businesses.

I care about building software that actually works in production, not just in a demo — that means clean architecture, defensive error handling, and being the person clients can call when something breaks at 9pm.
