What I'm looking for

I'm looking for remote .NET engineering opportunities where I can own scalable fintech or enterprise features end to end, improve performance and reliability, and collaborate asynchronously across time zones.

I build and scale .NET platforms for fintech and enterprise operations, including bKash systems serving 50M+ users and JustGo’s multi-region payments platform. I’ve improved API response times from roughly 110 seconds to 9–13 seconds and delivered secure Adyen payment integrations across the UK, US, Europe, and Australia.

At DataSoft, I led a zero-downtime migration of 500GB+ from SQL Server to MySQL, maintained 99.9% production uptime, and automated reporting that cut manual effort by 70%. I work end to end across ASP.NET Core, SQL Server, REST APIs, caching, CI/CD, and frontend applications, while mentoring developers on code quality and testing.
