Rockstar🎓
Top SchoolBas Smit is a seasoned System Engineer based in the Netherlands with 13 years of experience building and maintaining reliable infrastructure for mid-to-large organizations. Currently at bol.com after five years at Hostnet, he combines practical systems knowledge with hands-on development to solve production problems. He contributes to notable open-source tooling—having added core functionality and LLVM codegen fixes to bpftrace, a high-level Linux tracing language—demonstrating low-level debugging and performance sensitivity. With an academic background in electrical engineering from TU Eindhoven and Hogeschool Utrecht, he brings strong systems fundamentals and an engineer’s attention to detail. Colleagues rely on him for pragmatic improvements that reduce code size, increase testability, and make observability tools more robust. Despite a focus on backend systems, he regularly bridges gaps between platform, tooling, and operations to keep services observable and efficient.
