Systems Engineer at Elastic, Go Code Owner, and open source contributor focused on low-level systems, runtimes, compilers, and operating systems.
Contributor and Code Owner to the Go programming language go.mauri870.com.
- Runtime internals
- Assembler support and architecture-specific assembly routines
- Focused on enabling newer features for modern ARM64 cores (Neoverse V2/V3+).
- 128-bit atomics support for the Go standard library (targeting Go 1.28)
- Investigating timer precision, scheduling latency, and runtime performance improvements
- Working on loopvec, a SIMD autovectorizer for Go loops
Hardware needed: I am currently looking for hardware access to modern ARM64 cores (Neoverse V3+) to test architecture-specific features. Please reach out!
- Focused on Compiler-rt/ThreadSanitizer(tsan) support for Go.
- Focused on Elastic components and contrib repository.
Senior Software Engineer on the Logstash Data Processing team. Building the compiler and execution engine that powers Streams, Elastic's next-generation unified data ingest and processing platform.
Previously on the Ingest team (Beats / Elastic Agent / EDOT), focused on migrating to an OpenTelemetry component/collector architecture.
