Summary
🤩
Rockstar🎓
Top SchoolGreg Cusack is a software engineer with a decade of experience building high-performance, networked and distributed systems, currently focused on Solana validator technology at Anza Technology. He helped harden Solana's gossip protocol—adding monitoring, performance improvements, and more efficient data propagation—work that contributed to one of the largest Web-Scale blockchain projects. Greg blends deep research chops (PhD work on programmable compute infrastructure at CU Boulder) with production systems experience from roles at Solana Labs and Netflix, where he scaled container-level network telemetry. He is proficient across Rust, Python, cloud platforms and Kubernetes, and has built simulator and testing frameworks to analyze real-world network behavior. Based in Los Angeles, he maintains an active GitHub and a technical portfolio site demonstrating his research and tooling. Colleagues rely on him for pragmatic, measurement-driven fixes to complex distributed-network problems that surface only at web-scale.
