Hi, I am Ondřej. 👋 I am an engineer, a teacher, and a father of three. Thanks for stopping by my Sponsorship page.

🧍 What do I do

I have been working on Open Source Software projects for more than fifteen years. I currently have over 100 original GitHub repositories. My skills include ⌨️ programming in general, architecting rich client-side applications, networking (REST/RPC/WebSocket), 🔑 web security, 🖼️ web graphics (Canvas, WebGL), debugging and even reverse-engineering custom binary formats. I regularly give talks on various technological topics. I use my own slide deck software for cross-browser, cross-device responsive and interactive presentations.

I do many kinds of stuff, but most of my work is centered around Web and Frontend technologies. I created a Mind mapping app, a SQL Diagrammer, two file managers, two music players, a bruteforce vectorizer and a Guitar/Ukulele chord generator. I managed my very own competitor to Node.js for several years.

🎮 Games

I like Roguelike games and I am the author of rot.js, a popular collection of roguelike-related algorithms and tools. I often participate in 7DRLs; see a full list of my games. You can play all of them in your browser: that is the power of Web.

I play board games as well. I created a Railroad ink PWA, Dobble™ generator and a Mastermind AI in Rust.

💰 Sponsoring

Most of my OSS-related work has been done for free so far. Sponsoring my OSS contributions is a way to encourage feature development, faster bugfixes, more responsive discussions and more. Finally, it is a great way to say thanks in case you find some of my stuff useful or interesting.
