About Joel Hall

I have worked in a variety of market sectors over a broad range of technology platforms. Throughout my career I have sought to be an innovator, pushing the boundaries in all areas of software architecture, design, implementation, performance and usability. I am a firm believer in design first, code second methodology. I have been focused primarily in the .NET world for the last 20+ years, with a great deal of that time focused on GUI (WinForms, WPF, Blazor, HTML/JavaScript, MAUI) and custom controls development, although I have also written several NT services, developed advanced matrix based algorithms to model lobe formations, and developed Petrel plugins for reservoir simulation.Specialties: C#, JSON, XML, WSDL, XSD, SQL Server, WinForms, Threading, AppDomains, NT Services, WPF, C++, WebSphere MQ Client, MAPI, Visual Studio, Git, Jira, TFS/DevOps, Agile.
