Work Experience
iOS Developer
Freelancer
- Helped to bring a virtual makeup mirror to fashion shops, where customers could try out beauty products in real-time.
- Collaborated with transitioning a legacy Objective-C codebase to Swift while maintaining a shippable and working state all the time.
- Re-wrote completely a poorly designed app to feature modern programming patterns and technologies, so it'd be ready for release.

- Developed an app used to listen to audiobooks and read ebooks selected from a vast catalog of titles. That app is a white label app distributed to customers of public libraries, schools, and other institutions in Australia and the UK.
- Managed some verticals of the voice assistant system and performed as the technical lead of the mobile team for a smart speaker project.
- Onboarded new employees and guided them from junior to senior state.
