Preferred Environment

The most amazing...

...project I've contributed to is the Smart Speaker project of Deutsche Telekom, where I began as an iOS developer and became the mobile team technical lead.


  • iOS Developer

    2019 - PRESENT
    • 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.
    Technologies: Swift, UIKit, iOS, Bluetooth LE, Git, Jira
  • iOS Developer | Partner

    2010 - 2018
    CodingGene GmbH
    • 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.
    • Developed an app used by thousands of car dealerships in Germany to track employees' working hours, register inventory, and provide checklists for various processes in the dealership.
    Technologies: Objective-C, UIKit, iOS, Swift, Git, Jira


  • New Dating App, Spark Networks SE

    Worked on the development of a white-label app for company-owned dating apps.

    I was responsible for the initial development and conceptualization of the app architecture and the subsequent onboarding of additional developers.

  • Smart Speaker Companion App, Deutsche Telekom

    Right from the beginning, I took part in developing the companion app for the new smart speaker of Deutsche Telekom.

    I, later on, became the technical lead of the mobile team and managed some vertical features of the voice assistant.

  • Media Sales Solution, Audi AG

    An iPad app used by dealers in car dealerships that controls a virtual reality headset used by a customer to present car configurations in 3D.

    It also provides access to sales support material like videos and flyers and searches for used cars given a car configuration.

    I joined as a supporting iOS developer and later took over the role of the mobile lead.

  • In-store Beauty Mirror, Douglas

    I joined early on to create an app for the larger iPads to be used by customers of a Douglas store and try out makeup and entire looks using augmented technology.

    That feature was later on integrated into Douglas' eCommerce app.

  • IoT App, BRITA GmbH

    BRITA had an app developed by a digital agency that didn't meet their expectations, especially regarding code and architectural quality.

    I was brought on board to refactor the entire codebase, improve user experience, and add new features. This app is not yet released.
