Hello, I'm Daniel!

This is my personal space. I love computers, building software, and fostering a culture of passion and growth within my team.

I moved to San Francisco from Italy in 2015 to work for an Online Dating startup (my mum is still unclear of what I used to do) and I ended up biting the "Bitcoin bug" when I discovered the Whitepaper. Nowadays, I work for 0x with a really amazing group of people.

When I'm not working, I try to travel as much as possible and meet new inspiring people on the road. Some of them I end up doing really cool things with, others remain a great memory.

SF Python and PyBay

Since 2015, I've been on the leadership team for PyBay (the annual flaghip conference) and SF Python (the monthly meetup). Aside from lining up talks for SF Python and helping out with PyBay, I've also been helping attendees find jobs and encourage bootcamp students to become first-time speakers.


I've been a volunteer for Techtonica's 2019 cohort. Techtonica provides aspirational Bay Area women and non-binary adults with low incomes a pathway to careers in software engineering, and serves the recruitment needs of tech companies committed to diversity and inclusion in the workplace. I'm proud to say that 2 of the students that I've been directly mentoring have been chosen for an internship opportunity, and both of them have also given talks at SF Python!
