Architect and develop scalable enterprise applications in C#, elevate code quality standards, and mentor engineers while advancing modernization initiatives across .NET and frontend stacks.

Developed a new Maui application based off our existing Xamarin application for a new type of emissions requirement impacting all our customers and allowing us to expand our reach. Additionally made modifications to an existing Sync Service API used by the mobile applications to support this and maintain compatibility.

Refactored existing C# code to use EF Core instead of LLBLGen and made efficiency modifications to optimize the number of times data was being requested from the database providing improvements of up to ~50%.
