Senior Software Developer @ TeamHealth

About

Young, Determined Full Stack .NET Developer with a broad range of experience from Core Server application development, profiling, and optimization to building beautiful and lightning-fast user interfaces leveraging asynchronous processing and background pre-processing to minimize the time a user will ever need to wait for any component to load.If you have a team that needs leadership to drive projects to completion and are leveraging .NET, feel free to reach out. I have spent the majority of my career leading development teams and would love a chance to outright run projects when the opportunity is available. I have the experience doing so but have usually had to do so from a developer's role with my hands tied behind my back.There is nothing more satisfying than properly proposing and defining a project and then delivering it, as promised, on time or earlier. I chase that wonderful feeling every day!

Developed and provided Production Support for a modernization effort to replace a legacy Mainframe Settlement Application with a modern .NET solution backed by SQL Server.
