BangladeshWhat I'm looking for
At Portonics Limited, I develop and maintain features and REST APIs for My Robi and My Cirkle, serving more than 66 million subscribers combined. I also developed and deployed features and APIs for Eagle App, the agent application for ATOM Myanmar.
At Daraz BD (Alibaba Group), I architected a SaaS platform that enabled five business ventures to operate on one platform. I implemented OAuth2 authentication and role-based access control for it.

Earlier, at Swapnoloke, I led a 12-person development team for digital assessment solutions and managed projects from requirements gathering to deployment. My work has also included responsive WordPress websites at Connect Bangladesh, and I'm pursuing a software architecture career path with a growing focus on system design and microservices.
