About Me

Building systems that
scale & perform

I'm a backend developer with hands-on experience building scalable, secure, and efficient web applications. My expertise spans RESTful APIs, database optimization, and integrating payment and third-party services into production systems.

I've worked across travel tech platforms at Fly Far Tech — integrating Sabre & Galileo GDS, building payment flows with SSLCommerz, Bkash & Nagad, and architecting backend systems with Node.js, NestJS, and MySQL.

My travel technology experience goes deep: I work with Sabre, Galileo & Amadeus GDS, LCC and NDC airline APIs, and flight & hotel booking engines. I can build a complete travel agency platform end-to-end — from B2C booking websites to B2B agency portals with fares, PNR management, markup engines, and payout systems.

I've also published peer-reviewed AI research at an IEEE conference — a Bangla hate speech detection model using BERT and GRU achieving 98.87% accuracy.
