What we do

At Choice Computing we offer software design and maintenance services as well as technical problem solving.

We have many years of large and small system production,  maintenance and troubleshooting.

We have consulted for all size companies from the Fortune 500 , down to two or three man shops.

We come from a Mathematics/Physics background, (Mathematics at Cambridge UK, High Energy Physics at CERN and Laser physics) so no problem is too hard or abstruse, in fact the harder the problem the more we enjoy it.

We have many years of graphics and UI programming experience, and have produced whole graphics packages (CAD and GIS) that have sold thousands of copies worldwide.
