Rockstar🎓
Top SchoolShawn Tabrizi is a seasoned software engineer and runtime engineering leader with 13 years of experience building large-scale cloud and blockchain infrastructure. He helped shape Microsoft’s cloud identity and Azure Service Health experiences—driving OAuth 2.0 platform unification and service health models that improved onboarding times and operational response—before moving into core Substrate and Polkadot development at Parity Technologies. At Parity he led runtime engineering and contributed to foundational projects (ink!, Substrate, Cumulus), implementing XCM handlers, runtime improvements, and smart-contract runtime features in Rust. His background in physics and high-performance CUDA research informs a pragmatic, systems-first approach to engineering complex distributed systems. Based in San Juan, Puerto Rico, he blends product-minded program management with deep open-source craftsmanship and a long-running interest in decentralized systems and low-level protocol work. An early self-taught hacker from the PSP modding community, he still favors discovery-driven development and hands-on experimentation.
