I have worked for myself as a contractor. During this time I have had three clients in three different industries - fashion clothing, meat distributor and a plastics producer.
Two of these clients are DynamicsNAV users, and I have been helping with new developments within their system and interfacing with external applications.
The other client has an Access system which I have done some bespoke development on. Also, I have set up SQL replication for this client to my colocation server.

I administered/installed the new retail system to 200 odd stores around the country. This involved creating the Navision native databases, setting up connections with head office SQL database, fixing data issues & providing support to store staff.
