About me

Hey, my name is Jakub. Recently, I decided to quit my job as a data scientist, go traveling around the world and start working on my own projects. Hopefully, I will earn enough with it to cover my expenses (and some more).

Passive investing

I am a big fan of passive investing and have been investing for some time now. However, I experienced many difficulties (e.g. choosing the right portfolio and ETFs since the regulations in EU, figuring out how to evaluate the portfolio and how to rebalance it) on the way. So I was working on my own tools to help me with that. Since I believe I am not the only one with similar problems, I decided to make the tools and knowledge I gained on the way available for others. Some for some fee and some for free.


Since I love traveling and saved up some money, I also decided to let go of an apartment I was renting and buy a one-way ticket to Asia and work while traveling for some time.


Before starting working as a data scientist, I was first studying theoretical computer science and after that data mining and machine learning during my Master's studies the Czech Technical University in Prague (CTU). During my Master's studies, I spent one year studying at the National Taiwan University of Science and Technology (NTUST) in Taipei, Taiwan and one year at the University of Texas at El Paso (UTEP), US as an exchange student. During that time, I traveled around Southeast Asia, Mexico and the USA and fall in love with traveling.


While doing my Master's studies, I joined a small company, Datamole, as a data scientist. During my almost 5 years working there, I worked on many interesting data science projects for many clients. Since the company grew from 5 people to more than 50 while I was there, I became a data science team lead and was responsible for leading the team, interviewing new data scientists and communicating with the clients. Before that, I was shortly working as a data scientist at a company doing algorithmic trading and before that I was working for two and half years at one of the most successful startups in the Czech Republic, Socialbakers, working in a team that was responsible for collecting, storing and analyzing data from social networks.

Besides that, I was teaching two courses at the Czech Technical University in Prague (CTU), which is one of the biggest and oldest technical universities in Europe. The first course was distributed data mining, which I also partly prepared the materials for. I was teaching the theory behind some of the distributed data mining algorithms and how are they (or would be) implemented in Apache Spark. The second one was programming in Python.

Currently, I am open to data science consultations so if you like my work and what I am doing and need some help let me know via email or Twitter.
