I am owner and CEO of Advanced Computer Solutions, developers of Caddie software, used by architects, engineers, civil engineers, terrain modellers, interior designers and surveyors around the world. I take overall responsibility for our teams in both South Africa and the UK, as well as managing our development team in Bulgaria.Having started working with Caddie in the mid 1980s, when it was a bespoke two dimensional CAD system using a proprietary format, I was responsible for purchasing the intellectual property and source code, putting in place a new development team and rewriting the code, incorporating the Open Design Alliance's Teigha libraries, Siemens Lightworks library and several other libraries to create a full there dimensional DWG based CAD solution. Over the last twenty years I have driven the development of the product to include Digital Terrain Modelling, GIS, Heat Map technology and IoT integration.As one of the few members of the Open Design Alliance who utilise their technology in a full CAD system, I work closely with both our own technical team and the ODA teams to maximize the usability of the ODA technologies in the CAD environment.Whilst the development teams take responsibility for the core coding, since I am far closer to the users on a daily basis, I remain active in the design and development of the user interface, to ensure that the product meets the needs of our existing and future clients.
