I build business systems for small companies to run their operations. This involves requirments capture, database desig, back end proceses, front end design and build. Process wise I design and build all aspects and work closely throught=out the process with customers. Front end javascript and jquery drives app based and PC based interfaces for workers and system admins. Hosted on Linux virtual servers I administer the whole package.
I also design and build embedded devices. I have one customer building specialist lab equipment, for whom I create the firmware app interface and back end system.
