About me


My name is Tonia and I’m an Android Engineer living in Warsaw, Poland. I enjoy writing tutorials and sharing my knowledge, be it answers on stackoverflow or public talks (like on Mobile Warsaw). I particularly like qualitative apps with an emphasis on UI/UX.

Besides mobile technologies, I recently started to write websites (using HTML, CSS and Jekyll), like this one for my friend. I also read ~20 books a year and try to learn German by my own (through Duolingo and Memrise courses). I also wrote articles for Programista and a few more polish IT magazines. I occasionally play Civilization VI, Life is Strange or Tomb Raider, annoy my boyfriend who works from home, and eat chocolate until I feel guilty (not necessary in this order).
