About this gig

Still running your business on spreadsheets, emails and paper? I build web software that fits the way you work. It runs in the browser, on every device, with no installation.


Typical projects:

  • Appointment and booking systems
  • Customer portals with login and file upload
  • Dashboards and admin panels for your team
  • Connecting tools that don't talk to each other yet

You get a clickable design first, then I build in steps so you can test early. The full source code is yours.

Hi, I'm Tuma, a software developer from Germany. Together with my business partner I run a small studio that plans, designs and builds websites, iOS and Android apps and web software. Our own app is live on the App Store. We built it from the first sketch to the store release, so we know the whole way, not just the code. What you can expect: clear questions before I start, a fixed scope, regular updates while I work, and code that is reviewed and tested before you get it. I speak English and German. Message me before ordering so we can check that your project fits.
