Summary
🤩
Rockstar🎓
Top SchoolAngus Hollands is an Open Source Infrastructure Applications Engineer and PhD-trained developer with over a decade of experience building both full-stack and DevOps solutions for scientific and developer-focused ecosystems. He has a long history of high-impact open-source contributions—most notably maintaining and hardening the Awkward Array project in the scikit-hep ecosystem and improving tooling across Jupyter, xonsh, Sanic, and bqplot. Comfortable toggling between back-end bug fixes, test automation, and front-end interaction work, he ships reliable code and tests that prevent regressions in complex data and web stacks. Angus combines academic rigor from a PhD in Nuclear Physics with practical system-building at 2i2c and Princeton, regularly bridging research-grade numerical tooling and production-grade infrastructure. He prefers candid teamwork and is equally effective delegating or owning tasks end-to-end, bringing an understated knack for turning domain-specific research needs into robust, reusable open-source software.
