I've developed all sorts of database systems - ERP / CRM / sales / customer service / etc. My platform preference is FileMaker. I know Filemaker back-to-front, used it all my life (ever since it was part of the ClarisWorks package in the 1980's), vast experience with the PHP API, Instant Web Publishing, FileMaker Go, syncing, a whole range of plug-ins, image manipulation... you name it. http://www.eatyourveggies.com.au/search/FileMaker-Development/1?source=guru
