I'm a software engineer based in Dhaka, Bangladesh, currently at TechnoNext Ltd., building travel tech and fintech products for the US-Bangla Group. I work across the full stack: React.js and Next.js on the front end, Node.js and Express on the backend, MongoDB and PostgreSQL in the database, and I take features from architecture and API integration through deployment and maintenance. Most of my work lives at scale: a B2C travel platform serving 260K+ monthly visitors, a B2B agent portal used by 3,500+ partners, and a Bangladesh Bank-licensed payment platform handling merchants, transactions, and settlements. In practice, that means JWT and role-based access control, REST and GraphQL integrations, real-time messaging over Socket.IO, and production deployments on DigitalOcean behind Nginx and PM2.
