Profile
How I work
I am a full stack developer based in Dhaka, Bangladesh, building dependable backend systems and clean React/Next.js product interfaces.
Over the last 3+ years, I have worked across travel technology, hospitality SaaS, e-commerce, realtime messaging, and AI-enabled automation.
I care about products that are fast, observable, secure, and simple enough for teams to maintain after launch.
Current focus
SaaS backends, booking systems, operational dashboards, API reliability, and AI-assisted workflows that support real teams instead of adding noise.
