Rockstar🎓
Top SchoolJohannes Tax is a Principal Engineer based in Vienna with 9 years of experience leading teams and architecting high-volume backend systems and observability platforms. He is an observability specialist and active open-source contributor who worked on opentelemetry-cpp (notably HTTP client and trace propagation) and led efforts on OpenTelemetry semantic conventions for messaging systems. At Grafana and Microsoft he shaped distributed tracing backends, created a .NET OpenTelemetry distribution to simplify instrumentation, and formed multi-language instrumentation teams. At New Relic he combined low-level C/C++ work with product thinking—e.g., improving a PHP monitoring agent’s performance by 5–10% through memory optimizations. He blends hands-on systems engineering with strategic leadership and mentorship, focusing on shipping scalable, developer-friendly instrumentation and reliability improvements.
