Become a sponsor to Tsvi Mostovicz

Hi, I’m Tsvi! 👋

I’m a Senior Verification Engineer with a passion for software and open source. Originally from Belgium, I’ve been living in Israel for many years, balancing work, open-source contributions, and family life.

🚀 What I’m Working On

I maintain several open-source projects, including:

  • py-libhdate – A Python library for Hebrew calendar calculations, used in various applications.
  • Home Assistant’s Jewish Calendar integration – Helping users track holidays, candle-lighting times, and more.
  • Specman syntax for VSCode & Sublime – Keeping EDA tooling up to date for verification engineers.

I also write about software design, hardware verification, and the Hebrew calendar on my blog.

💡 Why Support Me?

Your sponsorship is a token of appreciation that keeps me motivated and allows me to dedicate more time to open-source work. It also helps me enjoy some little extras along the way.

If my work has been useful to you, consider sponsoring—every bit helps! 🚀

Thanks for your support! ❤️
