With over 35 years of professional experience developing Windows C++/C# desktop and web apps, I enjoy system programming, interfacing with hardware, and being thrown in the deep end. I am familiar with many technologies, including ASP.NET, SQL, Angular, WinForms, COM, Active Directory, Javascript, Typescript, OCR, and Git.

I build custom C# / .NET software for businesses that need reliable desktop applications, internal tools, and practical workflow solutions. My main experience is in Windows desktop development and business software. I work with C#, WPF, MAUI, ASP.NET Core, Razor, MVC, MVVM, SQL, Entity Framework, and Web API, and I’m also interested in Blazor-based internal applications. I’m a good fit for projects involving internal tools, workflow systems, document generation, printing features, integrations, and software that supports day-to-day operations. I work well on MVPs, prototypes, and milestone-based projects where the goal is to turn a business need into a practical working solution. I can take ownership of a project, communicate clearly, and make practical decisions to keep development moving. I can also help refine requirements as the project evolves. In many business applications, the best solution becomes clearer during implementation, and I’m comfortable helping shape that process while keeping the work structured and aligned with the client’s goals. I’m especially interested in .NET applications for internal platforms, admin tools, business automation, and AI-assisted workflow solutions where the technology supports a real business need. I usually prefer fixed-price or milestone-based projects when the scope is clearly defined, because it keeps the process transparent and predictable for both sides. If you need help building, improving, or supporting a .NET desktop application, internal business tool, or custom software solution, I’d be glad to discuss your project.

I can step into an existing codebase, understand the architecture quickly, fix bugs, improve performance, refactor safely, add new features, and prepare applications for production release. I am comfortable working directly with founders, product owners, designers, and technical teams. If you need an experienced engineer who can connect business requirements with practical implementation, I can help you move from idea or unstable codebase to a working, maintainable product.
