About me

January 2024, thanks Frido for the photo

Hi! I’m Václav [vah-tslav], but my friends usually call me Vašek [vashek]. Or Váša. Czech names are weird like that.

I grew up in Prague. I’ve liked computers and programming for as long as I can remember. This showed in different ways: first I got really into competitive programming contests (see CV) where you design and implement algorithms on a tight time budget. Then I started studying computer science at Charles University in Prague, where I got more interested in machine learning (like many CS students). For my Master’s degree I went to ETH Zürich to study both ML and algorithms further. I handed in my thesis in the summer of 2022. After that, I started working at Lakera, an AI security startup in Zürich. In March 2025, I moved to Paris to join Kyutai, a non-profit open science AI lab with a focus on audio research.

I also really like music. What I mean by that is mainly that I follow a lot of bands, read/watch album reviews and own several t-shirts with band names on them. Here are the artists I particularly enjoyed in each of the past few years:

2020: 100 Gecs, King Krule, The Strokes
2021: Black Country New Road, Squid, Daniel Johnston
2022: Black Country New Road, Jockstrap, Alex G, Weyes
2023: 100 Gecs, Alvvays, JPEGMAFIA + Danny Brown
2024: Charli XCX, Aphex Twin, LUCY (Cooper B. Handy), Ski Aggu
2025: Saya Gray, Smerz

On this webpage, I wanted to highlight the projects that I’ve done over the years, especially the ones that I did for fun, without being paid for it – not that the two are mutually exclusive. That includes games, videos, other coding projects and miscellanea.
