PROFILE
Jacob Shiohira
Worked extensively on the orca-so/whirlpools repository, delivering features that improved transaction reliability, liquidity management, and upgrade readiness. Focused on Solana blockchain development using Rust and TypeScript, this work included enhancing transaction construction with explicit compute unit limits, strengthening test coverage for Anchor account discriminators, and upgrading dependencies for compatibility with the latest Solana SDK. Implemented dynamic tick data support for flexible fee and reward calculations, streamlined CI/CD workflows, and improved deployment processes with Docker and GitHub Actions. Addressed robustness by introducing idempotent account creation and refining publishing workflows, resulting in a more resilient, maintainable, and production-ready codebase.
