What I'm looking for

I’m looking to build and scale backend platforms where reliability matters—APIs, microservices, and real-time concurrency. I want to own payment integrations, improve performance, and deliver safe migrations with zero downtime.

I’m a Software Engineer with 4+ years of experience building scalable platforms across transportation, logistics, and e-commerce. I focus on production-grade systems—especially API development, microservices architecture, and high-volume transactional flows.

At Jatri Services Ltd., I built the NSU Student Transport Platform end-to-end, including QR-based seat verification and BRAC Bank/bKash payment gateway integration. I also developed intercity bus booking APIs for 6,500+ buses nationwide, covering seat selection, concurrent reservation handling, payment verification, and digital ticket generation. I led a zero-downtime migration from MySQL to MongoDB to ensure full data integrity across live services.

I’ve contributed across backend and platform engineering, including leading a Laravel admin panel and delivering backend features in a NestJS monorepo using MongoDB and Redis. I’m also experienced in performance improvements and deployment operations using Docker, NGINX, Linux, and AWS S3.
