O2 TV Web ― Live TV and on–demand content streaming portal by O2 Czech Republic. Created concepts and prototypes of the web using real data and content. I helped deliver the portal's new IA, UI and tune production code (CSS). Launched in January 2018. O2 TV has currently ~650k customers. In cooperation with Tomáš Procházka.

Public Transport App ― An experiment with UI and data. App shows departure times of public transport lines from nearest stop, based on user's location. Data are in GTFS format, and the app functions in any city that provides data in this format (Berlin, NY, London etc.). In cooperation with Tomáš Procházka.

O2 Active App ― ITunes–like portal by O2 CZ, offering digital content (apps, music, e-books, magazines). Released in June 2016, redesigned in 2020. In cooperation with Tomáš Procházka we delivered concepts and designs.

Local Time ― A Chrome extension that converts time on the pages you visit to local time. No UI, no settings, just works. ~1000+ weekly active users.
