Rockstar🎓
Top SchoolMarcelo Juchem is a Principal Software Architect with 12 years of experience designing high-performance observability and distributed systems, now based in the Austin metro area. He specializes in low-overhead telemetry—from eBPF data sourcing and custom agents to time-series database optimization—and has built end-to-end monitoring platforms in modern C++23 with custom code generators and multi-language service infrastructure. Marcelo led core observability work at Flowmill (later part of Splunk) and created specialized testing and deployment environments for heterogeneous kernels and cloud orchestrators. His background includes systems and compiler-level contributions at Facebook (authoring the Fatal C++ library and Thrift optimizations) and performance engineering at Airbnb, reflecting deep expertise in serialization, JVM/C++ interop, and protocol inspection. Notably, he combines production-grade engineering with compiler and language design instincts, enabling efficient data pipelines and online algorithms at scale. He pairs founder-style hands-on implementation with architectural leadership, routinely shipping ultra-low-overhead solutions for large distributed deployments.
