Full Stack Developer & Systems Builder

I'm a Full Stack Developer based in Dhaka, Bangladesh. Over the past 2+ years, I've architected multi-tenant SaaS platforms, high-throughput POS retail engines, and reactive modern web storefronts.

Currently, I'm working as a Full Stack Developer at Manaz IT, engineering enterprise features with React, Next.js, TypeScript, Node.js, and PostgreSQL. Previously, I contributed to client projects at DOT Programmers, where I was promoted from Intern to full-time Developer within 3 months.
