Rockstar🎓
Top SchoolJoshua Gutow is a software engineer with 11 years of experience building robust backend systems for blockchain and layer-2 protocols, now contributing at Uniswap Labs in the San Francisco Bay Area. He has a strong Go background demonstrated through meaningful contributions to prominent open-source projects like Optimism and Celo, where he implemented gas tests, contract binding updates, Celo-specific transaction types, and fixed replica deadlocks. At OP Labs and Celo he focused on improving testing infrastructure and adapting CI-sensitive environments, showing an emphasis on reliability and maintainability in distributed systems. Trained in physics at Dartmouth, he brings analytical rigor to protocol design and debugging complex concurrency issues. Occasionally working close to the metal of blockchain primitives, he blends production-grade engineering with open-source collaboration on widely used Ethereum scaling stacks.
