Senior Software Engineer · Backend & APIs
MD TANZIBHOSSAIN.
15+ years building and operating PHP/Laravel systems, REST APIs, and high-traffic platforms — keeping production stable under load, from live national sports traffic to daily client delivery.
About
I'm a senior backend engineer based in Dhaka — I design APIs and data layers, then keep them fast and standing up in production.
Across 15+ years my work has centred on PHP and Laravel: REST API design, third-party and webhook integration, MySQL schema and query optimization, caching, and CI/CD automation. I work test-first with PHPUnit and PHPStan, and I've spent enough time on call to care about what happens when traffic spikes — including live-match load on a national sports platform. I've also led a team of six and mentored three engineers into promotion, but my hands stay on the codebase.
