Full-stack engineer in Chattogram. Go, TypeScript, Python — service discovery, real-time systems, and the frontends that consume them. Three years of production work before I started my CS degree.

Services in our fleet needed to find each other and know which instances were healthy. I built a VM-based health-checking and discovery system, then — when we moved to containers — designed a Docker-based replacement that ran alongside it without breaking anything depending on the original. Both systems coexisted through the migration.
The company needed a web app to reach wider audience. Took the full responsibilty of the product and developed it under a tight deadline of 1.5 working days...
Designed the service boundaries and system architecture for the product MVP — deciding what became its own service and what didn't.
I joined the industry in 2020, focusing mostly on backend systems in Go, and spent three years at Halalwedd building infrastructure — health checks, service discovery, and real-time messaging. I left the company in January 2024 and spent the rest of that year preparing for Bangladesh's highly competitive engineering admission tests. In February 2025, I got into CUET and chose CSE as my major to build the theoretical foundation I had been working around. I'm still building, and I'm currently working as development team lead at a local startup.
Chattogram, Bangladesh.
Alongside my startup I joined as development team lead at a local startup called Borno.
After a long break, I partenered up with a senior of my university to build a software startup called Kodaic. Kodaic is building its first product, which is predicted to launch in 2027.
After year-long admission preparation and admission journey, I was tired. I took a long break and started participating in programming competitions.
Got into CUET and chose CSE as my major to build the theoretical foundation I had been working around.
Left the startup and spent the year preparing for Bangladesh's highly competitive engineering admission tests.
Though joined as a freelance developer, later hired as Junior Software Engineer. Spent three years building web apps, backends, and infrastructure — health checks, service discovery, and real-time messaging.
Throughout this period, I learned new languages and build small projects
It all started for a science fare project(Arduino).
Email is the fastest way to reach me. But Facebook or LinkedIn works too...
