About

Being a software developer is more than just learning to program in a computer language. I have been building .NET web apps for years and multiplayer games since 2015, using Unity 3D using Photon Fusion (server-authoritative). I have also designed and/or worked on enterprise web sites from concept to deployment, some high-profile projects. I have served as a Senior or Lead Developer for years, mentoring other developers and encouraging them to use the latest technologies and best practices. For tutoring, I would focus on teaching design patterns, using events and encapsulation when designing applications and reinforcing the need to keep your skillset current as new technologies are released. I can give advice on how to focus your learning efforts to target specific types of development positions, and interviewing advice for finding a position within a software company. I had been a developer in C++ for about 10 years prior to using C# and focused on web technologies prior to working with Unity 3D.

While I have primarily been using Unity 3D and Microsoft .NET / C# recently, I have also utilized legacy technologies like Classic ASP, VB and VB.NET, COM/DCOM, worked with Linux/PHP/MySQL from time to time, and worked with the Microsoft SQL Server/Express/CE products for 10+ years. I also have formal SCRUM training, which is used by many companies for handling team project management.

For Unity 3D multiplayer networking projects I typically work with and recommend Photon Fusion along with PlayFab integrations, PlayFab Matchmaking, and PlayFab GameServers.

If your college project is a "Concept to POC" type of project where the Proof of Concept is the working software required for a grade, then I will also teach you to use a Git repository to manage the project (or Plastic/UVCS for Unity projects).

I can help you document the Project Scope, Functional Specs, create Design Documents, and build the presentation for your college project. We can build completed projects in a short time, both the user interface and the server components as needed.

My focuses are Unity 3D multiplayer, C#, .NET Core
