Gigi is the author of 21 Lessons, a popular book about lessons learned from falling down the Bitcoin rabbit hole. His current work-in-progress book, 21 Ways, tries to illuminate Bitcoin from multiple angles, using metaphors from biology, physics, engineering, and other disciplines. In addition to writing books, he launched and contributed to various projects over the years.

He is the creator and maintainer of bitcoin-resources.com and nostr-resources.com, a comprehensive list of curated books, articles, podcasts, and other resources that help to provide a multi-faceted understanding of Bitcoin & nostr.

In 2019 he launched the German-speaking Bitcoin podcast "Einundzwanzig" with one of his co-hosts which turned into a community movement that now spans multiple countries. In 2023 he launched Sovereign Engineering, a program for freedom tech builders that is dedicated to high-bandwidth collaboration, in-person communication, and iterative experimentation. He is passionate about privacy, human rights, and freedom technology.

As the president and executive director of OpenSats, he spends most of his day thinking about how to best support the development of free and open-source software as we transition towards an increasingly bitcoinized world.
