Career Profile

Andrew James Potter I graduated in Physics (2.1 BSc). I have worked as a developer and in particular as a Ruby-on-Rails developer. My main interest is education and I like to teach others the knowledge I have learnt myself. I have also tutored Mathematics privately. I also excel with technology. When I was 14 I emailed Nintendo asking what I needed to learn to make games. So from an early age I developed a strong interest in technology and began by learning the C++ programming language at approximately the age of 14 and learning GNU/Linux from the age of 15. I love pentesting with Kali Linux and Metasploit (ethical hacking). I am also fascinated by digital art creation in 3d and 2d and the application of Physics and Mathematics to create interactive art like videogames and simulations. I eventually developed a love for the Ruby programming language and in particular Ruby-on-Rails. I have developed a 3d Map App using Unity3d for iOS/Android/OSX/Windows 10. I discovered three confirmed bugs in Unity3d, which I was rewarded for by Unity. I have coached minority groups how to code (they taught me much more than I taught them). I am working on an off-grid P2P project which has a focus on education called QALB.


Professional Development

Apr 2020 - Present

Career Break I have been studying Artificial Intelligence, Elixir/Phoenix and React, alongside video game design, and other topics. In particular I have been using this knowledge to build my own personal P2P e-learning project; QALB. The essential idea behind QALB is to build a P2P e-learning platform, aiming to provide high quality animated e-learning stories to teach people regardless of their economic situation or background. QALB also acts as my portfolio encompassing React, Elixir, C++, QML, AI, storytelling and traditional talks with slide decks.

A list of side projects (in chronological order)

Strodes College Physics bridge building competition - Our team were awarded first prize at St. James’s Palace by the Duke of Edinburgh. “Nine of the college’s physicists won a bridge-building competition organised by the Science and Technology Research Organisation (SATRO). Working in a Physics lab in their spare time, Andrew Potter, Thomas Hayes, Nick Woods, Jan Nyeki, Maria Nyekiova, and Rob Evans designed, built and tested a bridge from glass fibre.” Press photo; August 2nd 2002;
Wave Simulation software using the wave speed equation - Written in C++ using OpenGL 1.1. Compiled using Visual C++ on Windows and GNU GCC on Gentoo Linux. Programmed by Andrew Potter 2002.
Dreamcast Pong Game - This was coded in 2003 on my PC using GNU GCC. The game was burnt to a CD which then boots up in the Dreamcast console. My brother is the ball.
Yateley School Map 3d - Programmed by Andrew Potter in 2017. Using Blender 3d and Blend4Web with Ruby on Rails and CoffeeScript.
QALB P2P platform - QALB is a reference to the heart. QALB is scaffolding for your community, including an e-learning platform which will come loaded with educational content. After 16 years of research and development (beginning August 2006), this is now being actively developed. QALB will be released under the AGPLv3 once it is ready. The desert Bedouin of Makkah and Madinah who asked me for my help in 2007, confirmed the need for me to build a free software education platform; their kindness and generosity left a mark on me. People who give whatever they have — despite having very little to give. One day I hope to give something back to them — for all of their generosity and kindness. The main motivation behind QALB is to reflect on my own personal struggles with advanced knowledge and to help others not to suffer the way I did when trying to learn this knowledge. The stories and talks will be freely licensed under the CC BY-SA 4.0, to reach as many people as possible. Despite being built on top of GNU/Linux, support for macOS and Windows is planned via QEMU and WSL2. I want to reach as many people as possible regardless of what technology they use. I plan to support x86_64 and arm64 initially. The art style of the animated stories is heavily inspired by Dédouze and also by Tyson Tan’s original friendly dragon concept. The gamified learning is happening via the Bevy game engine. The game development will use PlayStation 5 (and 4) controllers via SDL as the main recommended gamepad, with others to follow. QALB’s gamified learning concept was inspired by Shigeru Miyamoto’s Ocarina of Time and also by Rare’s Banjo-Kazooie. Microsoft’s open source Fluent UI will be used for much of the QALB interface.
QALB-Boy - QALB-Boy is a planned GPLv3 open source open hardware spec for running the QALB platform. QALB-Boy has an emphasis on building a modular eco-containerised off-grid operating system. The ultimate goal would be to have an open hardware spec which would enable educational AI learning in particular, alongside other educational subject matter. Essentially — QALB is an off-grid P2P network primarily focused on e-learning but also providing other decentralised apps. With zero dependency on the internet or the DNS domain name system. The current hardware prototype consists of an NVIDIA Jetson module alongside a cluster of Raspberry Pi 4 boards networked together. The focus is really regarding low energy use alongside practicality in areas of the world where the internet is not available.
QALB-Story - These stories are a work in progress and are licensed under the CC BY-SA 4.0 and are therefore free to share with friends and family. These stories will eventually be included inside the QALB P2P platform alongside animated drawings and gamified learning. The friendly dragon concept is based upon Tyson Tan’s original friendly dragon concept. Both stories with Abdallah + Safiyyah and Andrew + Xenia are included.
QALB-UI - The UI for QALB is a React-based interface. This will be released within QALB under the AGPLv3 once it is ready. This document demonstrates the various apps within QALB, this document is CC BY-SA 4.0 and is free to share with friends and family. Some Public Domain images from Unsplash are used to temporarily scaffold the UI. QALB-UI is still a work in progress. This document also acts as my React portfolio.
QALB-Talks - These talks are a work in progress and are licensed under the CC BY-SA 4.0 and are therefore free to share with friends and family. These talks will eventually be included inside the QALB P2P platform alongside animated drawings and gamified learning.

He has trained teachers in the use of the VLE. He communicates well with a variety of audiences and has shown himself to be persistent and determined in addressing the concerns of our users. Andrew has used his programming skills to good effect and has designed and built a Ruby-on-Rails (version 5) WebGL 3d Map App of the school which is published on GitHub YateleySchool/YSMap3d. He also designed and built a Ruby-on-Rails (version 4) Work Experience database system, which helped our work experience manager immensely. I can recommend Andrew to you without reservation.

Kind regards,
