Rockstar🎓
Top SchoolHans Hübner is a Principal Software Engineer based in Berlin with 22 years of experience building backend, embedded and cloud systems across startups and enterprise environments. He combines hands-on implementation (Common Lisp, Clojure, Java, Node.js, C/C++) with architecture, DevOps and product-facing responsibilities, having led teams, grown a B2B SaaS company, and co-founded a market-monitoring startup. His open-source contributions span niche but high-impact projects—from maintaining the Common Lisp Hunchentoot web server to extending node-hid for USB/Bluetooth HID devices and improving the Kong API Gateway—demonstrating a knack for low-level protocols and developer tooling. Comfortable across the full software lifecycle, he has particular depth in EDI/healthcare integrations, networking/packet processing, and database-backed systems. Known for pragmatic refactors and robust error-handling improvements, he brings both systems-level rigor and product sensibility to complex engineering challenges.
