About us

We build many kinds of software. That’s the point.

22Softwares is a software company with offices in Greece and Bangladesh, building for clients all over the world. The name says what we do: 22 stands for variety — client platforms across many industries, and free software across many categories.

Our story

Where we come from

22Softwares comes from Thessaloniki. Our team grew out of GPScom, in telematics in Greece since 2001, and Trakito, which ships GPS trackers from Thessaloniki to customers across Europe. GPScom now sponsors 22Softwares.

Building and running those products taught us what real-time systems and online stores really demand. Every Trakito device runs on ProtoTK, our Go tracker server, and the GPScom store runs on CS-Cart, where we have built many add-ons — one of them is now sold by 07 Software on the CS-Cart Marketplace.

In Bangladesh, our developers build client platforms and PMS, the free management system that students built for shops. Together, the teams in Greece and Bangladesh work for clients all over the world.

I love turning dreams into working software, and I dream of keeping the tech market moving forward with every skill I learn.

Supto leads engineering at 22Softwares from Dhaka, shaped by 200+ projects and no shortage of tough technical challenges along the way. He designs the software architecture and the algorithms, and builds across the stack — PHP and Laravel, Node.js and React, Flutter and Go — for the web, phones and desktops. He learns fast: when a better framework arrives, he is already shipping with it.

What we value

How we make decisions

  • Variety, with depth

    We work across many kinds of software and go deep in each one — protocols, payments, offline sync.

  • Built to keep running

    We judge our work by how it behaves years after launch, not on launch day.

  • Honest by default

    Clear estimates, plain explanations and no invented numbers — including on this website.

  • Give something back

    Free software like PMS is part of the company, not a side project.
