I’m a software engineer, Pythonista, Gopher, and prolific speaker from Berlin/Germany.

My day job is writing software that keeps a hosting provider and domain registrar running. If you want to know what’s on my mind, you should follow my tweets and my blog. My most personal post is about the books that changed my life.

In case you wonder how to pronounce my Czech name, it’s /ˈɦɪnɛk/. macOS’s say does a pretty good job at pronouncing it, so I’ve uploaded an MP3 of it.


I have spoken and keynoted at conferences and companies from California to Moscow and Tokio, and my talks have been consistently very well received. If you would like me to speak at your event, please contact me to discuss details.

Generally I’m happy to speak for free at community-organized non-profit conferences that have adopted a Code of Conduct, don’t sport a 100% male speaker lineup, and will pay for my travels (flights, conference tickets, and hotel). I love speaking at small conferences but I cannot afford to pay my way there.

I will also speak at your for-profit event if we can agree on a reasonable compensation.

Open Source

I’ve been involved with open source software in general and the Python community in particular for a long while and I’m a proud fellow of the Python Software Foundation.

I’m the author of several projects and a committer on many more – including Twisted and CPython. I also collect useful information on my blog.

Support Me

All of my writing, mentoring, conference speaking, and open source work I do for free. In some cases it even costs me money for stickers, travel visas et cetera.

This page serves non-tracking, non-intrusive, and high-quality ads via EthicalAds. However I do not have the traffic to generate any substantial revenue and I encourage everyone to use ad blockers anyway. Therefore if you like my work, any monetary expression of gratitude would be highly appreciated and would motivate me to carry on:

  • Ko-Fi is the simplest way to tip me once without having to create any accounts.
  • GitHub Sponsors is a great way to support my FOSS work with regular donations and even gets you a nice badge.
  • PayPal
  • Amazon wishlist

If you use one of my projects within your company, I would greatly appreciate it if you could subscribe to them on Tidelift:

In case you’d like to sponsor any other of my packages, please let me know!

Thank you!
