Summary

Rockstar🎓
Top SchoolFred Hebert is a Staff SRE with 16 years of experience focused on reliability, distributed systems, and resilience engineering, currently helping run production observability at Honeycomb.io. He is the author of several influential Erlang books—including Learn You Some Erlang for Great Good! and Erlang in Anger—and contributes deep operational tooling to Erlang/OTP and projects like rebar3 and the recon diagnostics library. His open-source work surfaces practical fixes and observability features (SSL improvements, debugging helpers, and build/plugin enhancements) that reduce toil in production systems. Based in Quebec, he combines a practitioner’s hands-on debugging sensibility with a writer’s ability to teach complex topics, and he advises incident analysis startup Jeli. An unexpected strength is his focus on small, high-impact changes—race condition fixes, cache bypasses, and tracing utilities—that measurably improve system stability.
