Coding & Apps

Apps, games and gadgets, coded from scratch. From Android apps and Roblox games to the code inside robots and sensors: if it runs on a screen or a circuit board, I can build it.

  • Android
  • Roblox
  • Arduino, ESP32 & Pi

What I can make for you

Software for screens and circuit boards

Android apps

Apps you install on your phone, with your own icon, offline support and a download page.

Roblox games

Whole games or new features for yours: vehicles, AI enemies, shops, pets, missions and more.

Browser games

Games that play instantly in any web browser, with nothing to download.

Electronics and firmware

Code for Arduino, ESP32 and Raspberry Pi: sensors, screens, motors, Wi-Fi and radio.

AI features

Add AI to an app or gadget, like the light designer in my robot's remote that turns a sentence into a light show.

Tools that save time

Small programs that do boring jobs for you, like renaming files, making reports or cleaning up data.

Examples

Apps and gadgets I've coded

The Flight Radar download page

Android appLive data

Flight Radar

A live map of the planes flying near you. Tap a plane to see its route and the air traffic control frequency it's probably on, then listen in live. You can search routes like LAX to JFK and follow a flight right in your notifications.

  • Android app and a PC version
  • Live flight data with a guess of who each plane is talking to
  • A download page with step-by-step install help

Self-Balancing Robot

I opened up a self-balancing triangle toy, backed up its factory program and wrote new firmware for it. Now it has a phone remote with live stats and lean controls, an AI light designer that turns a sentence into a light show, and updates over Wi-Fi.

  • New firmware in C++ for the ESP32 chip
  • A phone remote app with live stats
  • Wireless updates, no cable needed

Arcade Hub

8 original browser games in one hub: a grappling-hook climber, a crane stacking game, a sonar stealth game, puzzles and Rigworks, a sandbox where you build buggies, planes, rockets and boats from parts and see if they really work.

  • Game physics written from scratch
  • Plays in any browser
  • Also packaged as an Android app

Questions

Good to know

Can you make a Roblox game for me?

Yes. I can build a whole game or add features to one you already have, like vehicles, AI enemies, shops, pets, missions or leaderboards. You keep the place file and all the scripts.

Can my app go on the Google Play Store?

I build Android apps that install from a download link. To list an app on the Play Store you'll need a Google Play developer account in your name, and I can help you get the app and the store listing ready.

Do you work with hardware?

Yes. I write code for Arduino, ESP32 and Raspberry Pi boards and wire up sensors, screens, motors, Wi-Fi and long-range radio. I can design a 3D-printed case for it too.

Do I get the code?

Yes. When the project is finished you get all of the code, so it's yours to keep and change.

How much does it cost?

It depends on the size of the project. Send me your idea and I'll reply with a free quote and a timeline before any work starts.

Have an app, game or gadget idea?
