About this gig

Need a small program for your office or business that does exactly what you need - no subscription, no bloat? I build Windows desktop software in C# / .NET.


My own Windows tools run on real PCs every day (document viewer, PDF tools, screenshot and PC maintenance utilities under the UZYTAK name), and my first code goes back to 1996.


What I can build:

  • utilities: file renaming/sorting, image or PDF processing, converters, calculators
  • - business apps: customers, orders, stock, invoices, time tracking - with a local database
  • - reports and export to PDF / Excel / CSV, printing
  • - import from Excel or other systems
  • - tray apps, auto-start, scheduled tasks
  • - multi-language interface

You get a normal Windows installer, the full source code and a short user guide.


Tell me what the program should do (even a rough description or a sketch on paper is fine) - I'll reply with which package fits and an honest estimate before you order.

It all started in 1996 with BASIC games on a ZX Spectrum. Then came other professions, and they taught me the main thing: software has to solve a real problem for a real person. Since 2021 I've been building that kind of software under my brand UZYTAK from Poland - 20 apps on Google Play, Windows apps in Microsoft Store, language-learning platforms and websites. I help with Android and Flutter apps, Google Play publishing and rejections, website calculators and Windows tools. I don't know everything, but I learn fast and I'll tell you honestly if something is not my area.
