Top SchoolHector Guzman is a Technical Lead with 7+ years of experience building and scaling observability SDKs and telemetry platforms at Microsoft from Node.js and browser clients to Python back ends. He architects OpenTelemetry-compatible solutions, drove the GA Azure Monitor OpenTelemetry Distro, and led cross-team integrations that increased adoption and daily telemetry ingestion by tens of percent. Hector combines hands-on engineering—contributions to major open-source projects like OpenTelemetry and the Azure SDKs—with platform-level ownership, shaping browser observability standards as an approver and SIG representative. He has a track record of pragmatic migration strategies (notably a zero-code-change v3 shim that unlocked most customer adoption) and of improving service QoS through systematic telemetry. Based in Redmond, he blends front-end and back-end expertise with DevOps instincts, and additionally owns GenAI instrumentation work consolidating Microsoft’s fragmented OpenTelemetry efforts.
