I have been supporting and developing on c# and crm 3.0 And dynamics 365 for the last 11 years. this has included managing sql databases. Aspx websites. And ms sql ss reporting, creating and modifying. My first major addition to our in-house code was the Creation and implementation of an error logging DLL designed to catch and log all run time errors. This included logging to a sql database /txt file and emailing system critical errors to a designated email address. One of the things I was proud of was converting our Survey website to run on all the major browsers. At this point the original website was over 16 years old and designed to run on IE 4.1. Converting existing code to a more OOP based system. Refactoring existing code to run with more efficiency. Also included was management. Design. Implementation. Rollouts and testing.
