A software development company in Dhaka

We build software that runs real businesses

FullStack builds, sells and supports ready-to-use software for industries we know from the inside — made in Bangladesh, for the way business works here.

Our products

Built for one industry each, and built to be used every day

Every product starts with a business we understand deeply — its money, its hardware, its paperwork — and ends as software we run and support ourselves.

Services

Custom software, from the team that builds our products

Alongside our own products we take on a few custom projects each year — usually for businesses whose problem is too specific for anything off the shelf. Same engineers, same stack, same standards.

Web applications

Dashboards, portals and internal tools on Next.js and React, typed end to end, fast on a phone over mobile data.

Mobile apps

One Flutter codebase for Android and iOS — customer apps, field apps and the notifications that make them useful.

Integrations

bKash, Nagad, Rocket, SSLCommerz, SMS gateways, accounting software, and hardware that only speaks its own protocol.

Maintenance & support

Someone on call after launch: small releases every two weeks, monitoring, and a phone number that a human answers.
