Hello, I'm
Selim Reza
Building production-grade backend systems that serve real users and handle real money. Awarded "Best Backend Developer of the Quarter" at Join Venture AI.
About
Backend Developer. Production Systems Builder.
I'm a Backend Developer with 2 years of professional experience designing and shipping production-grade REST APIs, microservice architectures, and data-driven business platforms — built with a ship-it mindset that takes features from spec to deployment.
My work spans customer-facing platforms, admin dashboards, order lifecycle management, and payment orchestration (Stripe, Bkash). From e-commerce with live transactions to AI-powered property analysis engines behind isolated Docker networks — I build systems that handle real traffic, real money, and real users.
Currently a Backend Developer at Star Innovative Technologies Ltd. Previously shipped 3 production apps at Join Venture AI and built americatobd.com at FAARNS.
