I’m a Unity developer with over 13 years in game development and more than 8 years working with Unity on mobile and VR projects. I enjoy helping solo developers and small teams. That can be learning Unity from scratch, starting a new project, or figuring out an existing codebase that feels confusing or messy. I’m happy to help with gameplay logic, debugging tricky issues, basic architecture questions, code reviews, and preparing for Unity or game development interviews.

I'm the type of person that likes to delve into a new subject and figure things out along the way. I find it helps to learn if you just keep moving. I like to do my best to understand things inside out and I'll do my best to help you reach that same level.
I help developers and product teams solve difficult .NET backend problems, improve architecture, and turn prototypes into secure, production-ready applications. I have 14+ years of software engineering experience, including technical leadership, ASP.NET Core, C#, EF Core, distributed systems, Clean Architecture, DDD, cloud deployment, and AI/LLM integration. I can help with: • Debugging complex .NET and backend issues • Architecture and code reviews • Refactoring AI-generated or legacy code • ASP.NET Core APIs, authentication, and EF Core • MCP, RAG, LLM APIs, and AI-agent integration • System design and production-readiness reviews • CV, GitHub, interview, and career mentoring for .NET developers My sessions are practical and outcome-focused: we inspect the real problem, identify the root cause, implement or plan the solution, and leave you with clear next steps.

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](http://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, Photon Fusion, PlayFab, C#, .NET Core, [ABP.io](http://abp.io/) backend (Blazor/.NET MVC/SQL Server)
Through my journey as a developer, I have 7+ years of professional experience and helped 150+ clients with their development projects across several Technologies including **Node, React, NextJS, Javascript, TypeScript, Python, C++, JAVA, Unity Game Development**. Due to my strong understanding of Data Structures and Algorithms along with programming fundamentals, I can quickly learn any new language and concept which enables me to design and develop production-level systems. My mantra is to enhance my knowledge with practical applications. I focus on writing simple, clean, consistent and beautiful programs by prioritizing a well-thought design to ensure that they are easier to debug and maintain.
