Summary
🤩
Rockstar🎓
Top SchoolJacopo Notarstefano is a Senior Software Development Engineer with 14 years of experience building backend and front-end systems, currently at AWS after earlier research and engineering roles at CERN and startups. He blends rigorous mathematical training from the University of Pisa with hands-on engineering—shipping API integrations, improving client libraries, and tightening test coverage for Python GitHub libraries like pygithub and github3.py. At AWS he’s progressed rapidly through SDE II to Senior SDE, and his open-source contributions show a knack for both extending API surface areas (organization/team support, repo topics) and fixing subtle bugs. He’s comfortable across stacks—contributing to Google’s WebFundamentals frontend and deepening backend ergonomics—and often focuses on making developer-facing interfaces more reliable and typed. Notably, his background in experimental research environments informs a pragmatic, test-first approach to complex distributed systems.
