Matheus
Systems engineer building high-performance blockchain infrastructure and distributed systems. I build core protocol components, from off-chain processing to validator performance, focused on low latency, high throughput, and production-grade observability.
Systems Engineer SP, Brazil
Focus Rust-first systems engineering. Rust for high-throughput, low-latency infrastructure, with emphasis on validator and networking performance. Impact Scaled protocol and proving systems. Architected and owned core stack components that enabled a 60k+ TPS Solana system, improving zkVM internals and parallel GPU proving workflows. Background Research-driven engineering. Former bioinformatics researcher at the University of Brasilia, bringing data-intensive rigor to cryptographic and distributed systems.
2024–2025 Founding Engineer · Raiku Delivered core protocol MVP that enabled $14M+ seed funding, built a 60k TPS node, and optimized low-level QUIC networking for validator performance. 2022–2024 Software Engineer · RISC Zero Optimized zkVM performance and observability, built a parallel GPU proving service, and delivered a high-throughput Ethereum relayer. 2022 Software Engineer · Composable Finance Built a derivatives exchange (~$21M TVL peak) and implemented property-based testing for critical components. 2021–2022 Junior Software Engineer · Ferreri Designed client-facing APIs for core workflows and cut CI time by 50%+ with pipeline optimization. 2019–2022 Software Developer Intern · University of Brasilia Accelerated protein analysis by 30x+ and delivered interactive data-visualization reports for researchers.
