Worked on the grafana/opentelemetry-ebpf-profiler repository, delivering a refactor of eBPF map definitions to adopt BTF style. This change improved type safety and enhanced integration with BPF tooling, reducing the risk of misconfigurations and supporting future extensions of BTF-based mappings. The work involved C and Go programming, with a focus on kernel development and eBPF technologies. Collaboration across teams was emphasized through multiple sign-offs and code reviews, ensuring maintainability and alignment with project standards. The update enables safer and more maintainable BPF map definitions, laying the groundwork for ongoing improvements in the OpenTelemetry eBPF profiler’s architecture.
