Yoni Levy
Verified Expert in Engineering
Software Developer
Yoni fell in love with programming at the age of 11, and now he doesn't know how to stop. He started his professional career with C++ and has since transitioned his focus to more user-facing software. For the past decade, he was hands-on with all parts of the stack at high-profile startups. He's currently looking to help create exceptional iOS/macOS apps, with experience shipping sophisticated iOS apps since before the App Store existed.
