What I'm looking for

I seek backend roles where I can modernize legacy systems, optimize performance for high-traffic platforms, work cross-functionally, and grow into technical leadership.

I am a results-driven backend developer with 3+ years building and modernizing high-traffic platforms such as the Bangladesh Railway E-Ticketing System and Shohoz bus ticketing services.

I specialize in Laravel migrations (Laravel 4→10), RESTful API design, Redis caching, Elasticsearch optimization, OTP verification via queued jobs, and Docker-based deployments. I have led backend work on payment, authentication, notifications, and media processing for eCommerce and OTT platforms.

I collaborate with cross-functional teams to diagnose performance bottlenecks, document API behavior, and ensure system reliability under peak loads, delivering maintainable and scalable solutions.
