Summary
🤩
Rockstar🎓
Top SchoolChristian Bourjau is a data engineer in Berlin with 11 years of experience bridging experimental physics, cloud systems, and edge IoT. He holds a PhD in experimental particle physics from the University of Copenhagen and contributed to the CERN ALICE collaboration before pivoting to industry work that redesigned embedded-to-cloud stacks at Omnio and enabled industrial IoT. As founder of Cirrocumuli he built browser-based cluster computing, and later applied machine learning and data engineering at tetrel.ai and now QuantCo, delivering scalable data platforms. He combines deep scientific rigor with practical system architecture, often favoring browser-native and distributed solutions that make high-performance compute more accessible.
