WHO WE ARE

Software we actually use ourselves

POLPROG is an IT company founded by Damian Skrzyński. We build mobile apps for iOS and Android, web applications, browser extensions for Chrome, Firefox and Edge, and developer tools - over 30 projects so far. We also handle enterprise front-end engineering, including Tech Lead work at Fiserv on the global IPP Portal.
We start with the architecture
Every project starts with a clear plan: how the data flows, where the failure modes are, what stays simple. Clean code is a result, not the goal.
Front-end, extensions and mobile
Modern web interfaces, browser extensions for Chrome, Firefox and Edge, plus iOS and Android apps. Specialised, production-ready delivery, not generalist freelancing.
  • Front-end, browser extensions and mobile delivery
  • Enterprise track record with Fiserv IPP Portal
