Summary
🤩
Rockstar🎓
Top SchoolAlessandro Andrioni is a Senior Staff Engineer based in Berlin with 14 years delivering data-intensive back-end systems and database engineering. He has led data infrastructure and engineering teams at Nubank while contributing hands-on to projects like Materialize, improving SQL function support and Postgres compatibility to make real-time data platforms more interoperable. His open-source work spans core language and numerical libraries (Julia) and scientific tooling (Gambit), showing comfort across low-level math, build systems, and high-level API design. Comfortable both as an IC and manager, he mixes shipping production-grade database features with mentoring and technical leadership. A computational mathematician by training, he often bridges theory and practice—implementing precise numerical functions and pragmatic integrations that help analytics tools and GUIs work smoothly with modern databases.
