Welcome to the World of Andrew Johnston

A "Broad Spectrum" Architect

I am an independent IT consultant, architect, amateur photographer and keen observer of the world in general. Welcome to my web site!

Professional Zone

Trading as Questa Computing Ltd., I am an independent consultant specialising in the development of strategies and technical architectures which allow businesses to get the maximum benefit from their IT resources. Deploying a unique combination of managerial, commercial and current, active technical skills, I can help to deliver high quality, cost-effective business applications whether developed, procured or derived from existing assets. I have been described by clients as a "broad spectrum" architect, summarising my ability to engage in many problems at many levels.

Please browse these pages to find out about my skills and services, client profiles and some products and development ideas.

As well as practicing in the field of software architecture, I am also enthusiastic about developing the discipline, the people within it, and the way it is used. I have written and presented a number of papers on software architecture and related matters, am a founder member of WWISA and IASA, and run the AgileArchitect.Org website, dedicated to the practice of software architecture following the best principles of agile development.

My blog, Thoughts on the World, covers a number of technical topics, including architecture, agile development and detailed design issues. It's also the place to look for announcements on my products and publications. My professional book review topics include Architecture, Human-Computer Interaction, Project and People Management, Modelling and Analysis, and Programming and Development.

 

Photography Zone

I've always had a strong interest in photography, both as a practical tool to record our experiences in life, and as an art form. Have a look at my Photography Zone - a gallery of a few shots I'm quite pleased with, and a growing collection of articles, tips, utilities and thoughts on photography in general.

I have also published a number of book reviews on Photography and Photographers.

Personal and Fun Zone

I don't take the world entirely seriously. Look here for blog posts which may make you laugh, and reviews of amusing books.

My book reviews also cover Biography and Personal Endeavour, Construction and Civil Engineering, Cryptography, Fiction, Military and 20th Century History, Mathematics and Statistics, Physics and Cosmology, Psychology and Human Behaviour and General Science.

It hasn't been released for a couple of years, but you can also download old issues of the ever-popular "Coppertrees Calendar", which shows some of the things we have got up to!
