PROFILE
Jacob Shiohira
Over three months, Justin Shiohira enhanced the orca-so/whirlpools repository by delivering five features focused on transaction reliability, resource governance, and upgrade readiness. He improved transaction construction in Rust and TypeScript by refining signer placeholder logic and enforcing compute unit limits, reducing runtime errors and excessive resource consumption. Justin strengthened test coverage using the Anchor framework, adding unit tests for account discriminators to ensure accurate deserialization and lower production risk. He also upgraded dependencies and streamlined CI/CD processes, aligning the codebase with the latest Solana and Anchor tooling. His work demonstrated depth in smart contract development and robust DevOps practices.
