Marcel Popescu

Founder, Managing Director


I help teams reduce expenses maintaining their existing code by showing them how to clean up code, add unit tests and improve the overall design (including execution speed). I am currently focused on .NET (C#), but I am also proficient with JavaScript / TypeScript, Python and Delphi.

I’ve developed software solutions for a variety of industries including financial services, insurance and mechanical engineering. In addition to hands-on software development, I also have experience leading development teams and have managed hundreds of thousands of dollars worth of successful projects.
