Senior Software Engineer at Elastic, Go Code Owner, and open source contributor focused on low-level systems, runtimes, compilers, operating systems and exoplanet detection.
Independent research on exoplanet detection.
- transitgpu: Parallel Search for Alien Worlds: GPU-Accelerated BLS and TLS for Exoplanet Transit Detection (preprint)
- velociraptor: A fast GPU drop-in for TRICERATOPS that estimates whether a transit comes from an exoplanet or a false positive, with an exact transit light curve. (preprint)
Contributor and Code Owner to the Go programming language go.mauri870.com.
- Runtime internals
- Assembler support and architecture-specific assembly routines
- Newer features for modern ARM64 cores (Neoverse V2/V3+)
- 128-bit atomics support for the Go standard library (targeting Go 1.28)
- Timer precision, scheduling latency and runtime performance
- loopvec, a prototype SIMD autovectorizer for Go loops
- Compiler-rt/ThreadSanitizer (tsan) support for Go
- Elastic components in the Collector 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.
