John Dunning

I am a veteran IT Developer, Designer, Architect, Team Leader and Trainer.

I started my early days working in Informix 4GL, C and various flavours of Unix and worked for a number of International and Government clients - spanning the UK, USA and Europe. 

I designed systems, developed systems and worked as a Unix Systems Administrator.

As the IT industry changed and evolved I worked on some of the very first Java systems, worked on the Secure AIX Kernel and worked on a large number of multi-tier ecommerce and management systems.

With the birth of the iPhone, I worked on a number of iOS apps from the days before ARC and then Swift.

Some of my major achievements include 

- designing and writing a Database Engine for IBM

- writing Device Drivers for emulating Top Secret Data Tapes

- writing a Programming Language

- working on the AIX Secure Kernel

- establishing a specialist Training Company for IT Contractors

I have a passion for developing systems and an equal passion for training.  I hope you find my courses interesting, useful and fun.
