Software Infrastructure Engineer | System Programmer | Performance Engineer.Obsessed with Observability, Instrumentation, and low-level programming.🤔 Slow thinker. Open Source Enthusiast. Mentor (CNCF LFX, Google Summer of Code, CommunityBridge, GoBridge). Blogger and speaker. Introverted Human (not Cylon, I guess).😄 Pronouns: He/Him

🔭 Deep in the trenches of Go runtime and compiler internals, building AST manipulation tools for injecting instrumentation systems. Working on Go instrumentation and profiling at Datadog APM. Keeping a soft spot for profiling while tinkering with Go and its toolchain.🌱 Exploring engineering leadership, LLM internals, and automating Personal Knowledge Management with Claude Code and MCPs.

Current Projects

OpenTelemetry Go Compile Instrumentation - Prototype compile-time instrumentation for Go, exploring zero-touch observability
Datadog Orchestrion - Source-based compile-time instrumentation for Go, enabling deep APM without manual code changes
Datadog dd-trace-go - Datadog APM tracing client for Go
Prometheus client_golang - Prometheus instrumentation library for Go applications
