About Me

Here are 7 interesting facts about me:

  1. When I was 16, I wrote an e-book about object-oriented programming in PHP. As I discovered later, this book was recommended as material for students in their 4th year at the university I attended. Sadly, I finished my studies after getting a bachelor’s degree in my 3rd year, so I couldn’t study from my book.
  2. I attended several conferences as a speaker. The first one, many years ago, was WebExpo, the largest IT conference in central Europe. This was the first time I lectured in front of hundreds of people. In addition, the whole talk was in English, and until then, I had never spoken in a foreign language for more than 5 minutes. I was scared so I memorized the whole 1-hour talk. Never give up!
  3. I am very interested in language learning. I have started learning Mandarin Chinese as the most challenged language in 2018. Currently, I am able to hold a simple conversation in 普通话 (Standard Chinese). Since 2020 I have started learning Russian. Привет!
  4. In 2016, we released a new app called Teeta to help sellers dealing with a new compulsory registration of sales law (EET). It took us only 4 weeks to build a project from scratch. This solution was unique because it issued only web-based receipts. The project attracted so much attention that we were invited to a personal meeting with the Czech Prime Minister.
  5. Between 2017 and 2020 I lived in Asia and worked remotely. I visited all countries in East and South East Asia. I spent most of my time in Japan and China, but I also lived for some time in the central Gobi, in the middle of nowhere.
  6. In 2015, I bought a bicycle and started my 9000 km long tour from Czechia to Azerbaijan.
  7. In 2019, I crossed Taiwan from the northeast to the southern point. It took me about one month and cost me 2 pairs of shoes.
