Mobile App & Full-Stack Web Developer
I build Android and iOS apps, full-stack websites and the servers and APIs behind them — with a business mind. Every product starts with one question: how does this help the customer earn more or work easier?

Active Bangladesh’s Bengali due (baki) management software
In most Bangladeshi shops, credit still lives in a paper khata and the owner’s memory. When a customer doesn’t pay, the shop quietly loses money — and asking a friend face-to-face strains the relationship. DueTrack sends a polite SMS reminder instead: the money comes back, and the respect stays.

Business philosophy
A business succeeds only when the business owner thinks about the customer’s profit — not their own.
That’s the rule behind everything I do now — client apps, websites and DueTrack. If a product doesn’t make the customer’s life easier or their business more profitable, it isn’t finished yet.

Journey
Teaching taught me to explain clearly. Sales and running businesses taught me what clients actually need. Today both shape how I build software.
