I've been an experienced programming contestant and for that reason my style of solving problems became like fast and correct - that's everything we need. Writing code has been my hobby since I was 13 and it's the perfect age for studying IT. Those circumstances gave me an ability not only to repeat after another programmers, but also to develop my own tricks, ways of solving problems.

I work on the Swift compiler for fun. If you use Swift, you're running my code! I run an iOS development company. My clients include Fortune 500s, governments, and startups. I'm a hacker at heart and I like solving difficult technical challenges. I know my way around graph theory, compiler/interpreter internals, algorithm design, computer vision, project management, test design, and much more. Chances are, if you have a problem that can be solved by writing software, I can help.

“I am completing a project for class and the tutoring session with Matei was very insightful. He helped me create a working contact form that I will use in the future for potential employers to reach out to me directly. He also helped me edit and refine my code so that it will be acceptable when I submit the final project. I would recommend booking Matei!“
