About Me

Published October 30, 2025

I am Jiri Knesl, a developer, economist, entrepreneur, interested in many fields that include philosophy, art, making things.

If there was one word that would describe me the best, it would be a Maker. I love making things.

Some facts about me:

  1. In SW development, my main interest is Clojure, machine learning (not just LLMs, I am quite interested in Bayesian networks, decision trees, and recently in causal inference & causal trees). All this is related to my interest in operations research.
  2. During my BA & MSc studies in economics, my two strongest parts were all applied mathematics (mainly operations research, and any form of optimization) and management.
  3. I have been to many countries, never counted them, but I average 20+ flights per year.
  4. I have a family. I am married and have two kids.
  5. I am originally from the Czech Republic, however, for half of my adult life, I live abroad, mainly in English speaking countries.
  6. I have a company called Flexiana which is probably the biggest Clojure softwarehouse in the world. I have hired people from 40-50 countries, and at every single moment, we give work to people from 25-35 countries.
  7. I care deeply about human rights. The ones I care about the most are: free speech, privacy (including in financial transactions), property rights, and open source. I support plenty of causes, personally and financially. Examples include Human Rights Foundation, Electronic Frontier Foundation, Mises Institute. Over years, I have contributed to a number of charities and causes.
  8. Also, I care a lot about Clojure. Through my company, we have contributed tens of thousands of dollars to open source authors and other causes. Some of that anonymously.
  9. I started programming in 1992 in QBasic, and 1997 in Turbo Pascal and Delphi. I started building dynamic websites in 1998. For 2 decades, I am working professionally as a developer, team lead, consultant in SW field, CTO, startup co/founder, and CEO.

My goal on this website is to explore various topics that might have absolutely nothing in common with any of the above. Mainly, content curation, art & design exploration, or contents I believe should exist and they doesn’t.
