Engineer at GoHiring who delivered a wroclove.rb 2025 lightning talk sharing the company's observability story. Advocates open-source observability backends (Elastic, Grafana) over proprietary vendors, kernel-level instrumentation via eBPF, OpenTelemetry as the emerging standard, canonical log lines, trace IDs, RED metrics, queue time, and treating observability as a developer (not ops) responsibility. Ends with a pitch — GoHiring is hiring.
