Petr Hollan
Analyst. Chess player. Athlete. Below-average retail guy.
FIDE Master, marathon runner, and someone who cannot do hobbies casually.
By day I work on BI in retail. On the side I experiment with AI and build my own things.
If you want to find out what I actually do and why I do so much of it, you are in the right place. At least the first question has an answer here.
What I am working on
BI Analyst in retail (Albert / Ahold Delhaize). Databricks, PySpark, Power BI.
Thesis on AI adoption in Czech companies — done. Now running my own LLM and automation experiments.
This site, App Compare and a few other things I enjoy building.
FIDE Master. Coach and occasional player.

Co bude můj další side quest
Šachy, studentské akce, Samsung, zlomený malíček v Thajsku a návrat do Albertu. Pohled zpátky na několik etap a přemýšlení o tom, co přijde dál.

About me
I work in data and artificial intelligence. I studied at the Prague University of Economics and Business, where my master's thesis examined how Czech companies adopt AI in practice.
Outside work I'm a FIDE Master in chess, I run marathons, and for over four years I organised sports events for students at VŠE with the 4FIS association while serving as a student ambassador. I enjoy bringing people together, whether it's a tournament or a workshop. I like to travel and see how things are done elsewhere.
