Technical Lead at HomePay LLC, in charge of an MFS Aggregator System for international remittance into mobile wallets.
I specialize in high-throughput C# and .NET microservices, Azure Functions and Kubernetes, shipped through modern CI/CD pipelines. Underneath the cloud work are deep infrastructure fundamentals: I started in 2016 as a founding network engineer at an ISP startup, and today I run secure peer-to-peer VPN partner integrations and self-hosted network environments.
My first step was a small one. In 2011 I opened a Gmail account and made a Facebook profile, and I couldn't stop wondering how it all worked behind the screen. In 2012 I learned XHTML and put my first website live on Wapka, right from my phone. In 2013 I learned my first programming language, C, and in 2015 I went to Chittagong for my first national programming contest. That's where my journey in tech really began.
In 2016 I became a founding member and the network engineer of Roshni Communications, a new ISP in Cumilla, designing and running its network and operations center. Then I moved up the stack one step at a time, and in 2022, a few months into my CSE degree, I joined HomePay as a QA engineer. Today I'm the technical lead of the Mobile Wallet Remittance Aggregator, moving money from around the world into MFS wallets in Bangladesh.
Outside work I love traveling and exploring new places, so if you know somewhere worth seeing, say hi.

Most of my C# and .NET work lives in private company repositories, so it doesn't show up in my public GitHub languages.
Say hello. I'm open to new roles, collaborations and interesting problems.
