Just Eat Takeaway.com

Mid 2010s I thought it would be nice if I got some steady employment so I could reliably pay my rent.

The app(s) go by many names these days:

  • Just Eat
  • Lieferando
  • Thuisbezorgd

.. and a bunch of others.

At the time of writing the JET apps serve about a 100 million users. (or 10x the population of my small village called Greece)

The trick in writing a nice android app is making it extensible for:

  • migrations
  • buyouts
  • mergers
  • new markets
  • abandoned markets (!)
  • ....and all sorts of corporate takeovers

The JET android app mono-repo has been through quite a few of those throughout the years. 🫡

ADB Extension for Command Palette

A Windows 11 Command Palette extension (PowerToys) for Android devs. Exposes common ADB operations directly from the command palette.

Wrote this cause I kept repeating the same ADB commands on the terminal.

I use it for my own personal projects in order to turn stuff on/off without worrying about distribution on Microsoft Store/Google Play etc.

It is a simple ktor app on Railway.

In the end, it's all just a JSON file, eh? 😊
