I’m Filip Vizitiu.

• I worked as a jazz trumpet player from 2019-2021. I studied under Valery Ponomarev and Ingrid Jensen, and mostly played in NYC. Hard bop was my favorite.
• From 2021-2024, I worked on Juicebox, a platform for crowdfunding and operating projects on Ethereum. We helped fund projects like ConstitutionDAO and Julian Assange’s legal defense, facilitating about $200mm in payments as a bootstrapped DAO. I worked on documentation, the governance process, infrastructure, our Discord server, spam detection, our multisig, and the website. I spent lots of time talking to Juicebox users.

I left Juicebox in late 2024 and have been researching recommender systems and mechanistic interpretability. I’m interested in classical antiquity and theology. You can see some of my work on GitHub. My email is f (at) filip.world.
