04About
About me
I'm a Full-Stack Software Engineer, AI Developer and startup co-founder based in Dhaka, Bangladesh. Over the past 4+ years I've delivered production web and mobile products across fintech, ed-tech and healthcare, owning features end to end, from specification and architecture through to production deployment.
My recent work sits at the intersection of product and AI: integrating LLMs, real-time transcription and voice synthesis (Claude, Deepgram, ElevenLabs and StackAI) into production features. At Quanteron I lead engineering, driving architecture decisions, code review and product strategy.
I thrive in high-ownership, fast-moving environments where product thinking matters as much as engineering, and I focus on building scalable, maintainable systems that solve real-world problems.
What I'm looking for
- Full-stack or AI product engineering roles
- High-ownership, fast-moving product teams
- Remote, or on-site with relocation
