Rockstar🎓
Top SchoolYutaro Mori is an experienced software engineer and advisor based in Tokyo with 11 years building production-grade backend systems and developer tools. He has driven large-scale engineering efforts at MongoDB—designing CI for 50+ engineers, an index recommendation engine, and a robust backup service—and now advises and engineers at UMA on decentralized finance primitives. Yutaro contributes to prominent open-source blockchain projects, notably prysmaticlabs/prysm (Go Ethereum PoS client) where he fixed race conditions and began the Beacon Chain Sync Service, and UMAprotocol where he improved price-feed and oracle tooling. He blends deep systems and distributed-systems expertise with hands-on scripting and contract-level changes, enabling both infra reliability and protocol correctness. Known for pragmatic refactors and test-first fixes, he favors durable designs that simplify long-running services and reduce operational risk. Fluent across stacks—from core Java and Go services to Python scripts and Electron UIs—he brings a rare combination of fintech, DB, and blockchain production experience.

UMA Protocol Running on Ethereum
Role in this project:Back-end Developer
Back-end DeveloperContributions:32 commits, 22 PRs, 8 pushes in 4 months
Contributions summary:Yutaro primarily focused on enhancing the price feed functionality within the UMA Protocol. They updated scripts to support CNH/USD prices, added a script to resolve oracle prices, and developed scripts for creating and interacting with expiring derivatives. The user also made modifications to contract code, including adding functionality to the `AddressWhitelist` contract and updating the `CentralizedOracle` contract. These changes demonstrate a strong understanding of the protocol's core mechanics and pricing mechanisms.
