PROFILE
Greg Mefford
Worked on the grafana/opentelemetry-ebpf-profiler repository to enhance observability for BEAM workloads by developing a minimal unwinder for the BEAM virtual machine. This feature, implemented using C and Go with eBPF and system programming techniques, enabled more comprehensive stack tracing and improved error diagnostics in production environments. The approach focused on unwinding stack frames within BEAM-based systems, allowing for richer stack traces and more effective incident response. By laying the foundation for broader BEAM support in stack unwinding and error handling, the work contributed to reducing debugging time and improving the reliability of performance profiling for BEAM workloads.
