Things I've designed, coded, and shipped — my own products, my own businesses, and digital solutions for clients.
My own lifestyle brand, on a store I built end to end: catalog, cart, checkout, coupons, wishlists, reviews, and a bilingual (English/Bengali) storefront. Role-based admin with stateless JWT, a configurable CMS, Meilisearch product discovery, and local payments — bKash, Nagad, Rocket, COD. Runs on Oracle Cloud ARM with a webhook-driven CI/CD pipeline.

I build complete digital solutions for clients — e-commerce stores, admin dashboards, booking and management systems, and custom backends. Everything above I built myself, end to end: design, code, deployment, and hosting. Yours can be next.
In 2026 I started a bag and leather goods brand in Dhaka — backpacks first, sourced and sold with an engineer's mindset: test small, measure everything, automate the boring parts.
What makes it different: every part of the operation runs on software I wrote — from ad tracking to order management. This page will grow with real numbers, lessons, and honest mistakes as the brand grows.
