Feb 2018: KHKode Website

KHKode website under development. Basic content completed. Now attention needed to design.


Jan 2018: Trident

Currently working on a web and mobile application called Trident.

Trident is a system for managing plant defects in the workplace. Users may use either an app on their mobile device or the web application to report defects. A photo can be uploaded at the same time to illustrate the nature of the defect.

A controller can view new defects with the app on their mobile device or web application and dispatch the job to a fixer. The fixer is notified and can view the list of jobs on their mobile or web application.

Once a job is completed, the controller and end user are notified and the job can be closed.

For information and a demo version, checkout Trident here.

About me

My name is Karl Holden. I am a freelance software developer. I started coding in the 1980's when home computing first became viable. The first computer language I learned was good old BASIC on the ZX81! This lead swiftly on to machine coding and assembler.

Over the years, I have learned to programme in many computer languages on various platforms.

A large part of my career was as a Systems Engineer for Traction and Rolling Stock. A significant part of this was data gathering and analysis using different software tools.

At present I have turned my full attention to software development. The main areas I am concentrating on are mobile applications, websites, web+mobile apps and spreadsheets.

Please feel free to contact me for any queries or quotations.
