Hubert is an incredibly fast learner; -he was once able to pick up a musical instrument in the morning and play nice tunes by the afternoon. He has the same skill when it comes to working with new technologies and on new projects. He values high-quality code and attention to detail, and he cares deeply about great UX.

Music player for iOS written in React Native and Swift. Small project I've started for myself as the apps I've used before grew too convoluted for my taste.

Handwriting List

Designed and developed a mobile application for creating and managing handwriting lists. Very natural handwriting engine created in OpenGL ES. The app design was ahead of its time: the app looks and feels natural to iOS 7, but was created earlier than that system.
