Updates to existing C# Skype for Business CTI App -- 2

I have an existing established Windows Form C# application (.NET 4) using Unity Framework. The application connects to Microsoft Lync/Skype for Business and triggers record pop ups in Dynamics CRM,.. it also has a mechanism to pop other address books and has been written in a 'plugin' architecture way by a clever developer in the past. I am looking for an experienced C# developer to help progress a few aspects of the application. Ideally you will have worked with the Microsoft Unity framework and maybe also worked with the SkypeCOM object in Windows to access consumer Skype. I am after someone who can get their head around the applications architecture and then help me fix a few logic bugs in the popping/matching logic and help develop future plugins.. I want to look at integrating with [login to view URL] records and maybe other sources of databases with phone numbers to match. Immediate work to do: Updates to config file forms/options to hide/show some of the tabs in the application. Diagnose and fix a couple of logic bugs between the UI and the matching logic (option in UI checkbox not lining up with the right condition logic in the matcher). Also look at the very basics of some code for Skype (Consumer) integration and progress further.. have high level working but needs refining and finishing. Future work: Understand the 'plugin' way the app is written to extend writing some connectors to other systems like [login to view URL], autotask etc
