C# & Azure Cosmos

Project Summary / Role Overview We are seeking a C#/.NET developer for a contract-to-hire role. This developer will work alongside a current resource that will eventually roll-off. The intention is for this new developer to ultimately replace a highly autonomous position, requiring the ability to operate with minimal oversight. The initial assignment is to upgrade three existing C# applications from .NET Framework 4.6.2 to .NET 11, following modern architecture principles and best practices. This is a rare opportunity to refactor foundational systems, so quality, maintainability, and performance are critical. Until the new code is fully transitioned, this developer (together with the existing resource) will also address bug fixes in the legacy codebase from time-to-time. The developer should be a strong advocate for unit testing, code quality, GitHub, and Azure App Services deployment.
