I turn work people do by hand on phones into software that runs on its own.

Founder of MationX, a paid SaaS that automates real Android phones, from one device to a client's fleet. I designed, built and operate all of it on my own: web app, backend, realtime layer, billing and the native Android engine.

Before that, and alongside it, 50+ custom automations for clients since 2024. I build with AI coding agents every day, and I own the decisions: architecture, security and what happens when production breaks at night.

Story

From Fiverr orders to a phone fleet.

I started automating Android phones for paying clients at fifteen, over a summer on Fiverr. The work kept coming, so it became TaskerProjects, then MationX, and then a platform so I didn't have to build every automation by hand.

About

Hi, I'm Petr

I'm seventeen and I live and work in Prague, from my own office on Arbesovo náměstí in Smíchov. A court granted me full legal capacity at sixteen and I've been self-employed since, so I can sign and invoice like any contractor.

I design the product, write the code, run the servers and talk to the clients myself. I care a lot about the details people never see: deploys that don't drop a single phone, permissions checked on the server and not just in the UI, interfaces that feel finished.

I'm still at Smíchovská SPŠ, studying IT. Right now I'm looking for a part-time role or contract projects where I can own something real.

  • Design to production, on my own
  • Self-employed, invoice directly
  • Prague or remote
