I'm specialized in database applications for fields like accounting systems, ticket reservations, medical records, inventories etc. The applications I build can feature data acquisition from different devices, and sometimes they are integrated or made part of other larger systems (SAGE, QuickBooks etc). I use the following technologies: VBA, VFP, MySQL, MS SQL Java but also web-based front ends: php, ASP, .NET, Flash. I also build apps for Android and iOS devices, again with remote DB features (portable POS, delivery managers etc).
