Worked on the cilium/tetragon repository, focusing on backend development and system programming using Go, BPF, and Protobuf. Delivered a refactor of the policy filter to use program.Map instead of ebpf.Map, improving lifecycle management and integration with Tetragon’s sensor infrastructure for more reliable policy enforcement. Addressed a critical issue in protoc-gen-go-tetragon by ensuring deterministic selection of Tetragon-specific proto files, which reduced build failures and prevented third-party import issues during code generation. The work emphasized maintainability and traceability, isolating policy filter logic and aligning generated code with project requirements to support easier future enhancements and stable contributor experience.
