Welcome to my personal page. I am Ján Bogár. Forever curious, scientist at heart, a bit of an adventurer. I like old sci-fi, deep ideas, in my free time I rockclimb. This page contains my blog and a few things about me.
What I like
- I like sci-fi and fantasy: Dune, Malazan Book of the Fallen, Asimov, Discworld series, Harry Potter and Methods of Rationality, War of the Worlds (fight with the aliens from the pen of an author who lived in the era of steam engines is absolutely magical). I like music: Greta Van Fleet, W.A.S.P., Led Zeppelin, Omnia, John Butler, Čechomor. I like good people. I like rock-climbing, puzzle hunts and mountains. I like quantum mechanics, Fermi’s estimates and coding in Python. I like webcomics: xkcd, Gunnerkrig Court, SMBC, Order of the Stick. I like silly questions with serious answers and serious questions with silly answers. And curd cake.
What I can do
- Machine learning engineer/data-scientistist since 2017 (I have experience with work in startups (Merlon,HealthMode), public institutions (Moravian Library) and international corporations (Anthology)):
- Segmentation and classification of image and sound with neural networks, Bayesian Inference, Topic Modeling and Natural Language Processing .
- Languages: primary Python, but I have also worked on projects written in Typescript, Clojure and Rust.
- Tools: DVC, CML, Snowflake
- Msters degree in solid states physics at Commenius University, Bratislava. The topic of my diploma thesis was superconducting quantum bits.
- Long experience as a volunteer organising correspondence competitions in math and physics for children (Pikomat and Pikofyz):
- Formulation of problem questions, coordination of volunteers, giving lectures, supervising at summer camps.
