Career Profile

Andrew James Potter I majored in Physics. 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. I am working on a community scaffolding project which has a focus on education and free courses called qalbAI.
