Worked on streamlining developer workflows and improving reliability across two repositories. In CrocSwap/perps-app, introduced root-level pnpm scripts for linting, type checking, and testing, allowing developers to validate code quality from the repository root and standardizing tooling across the monorepo. This reduced onboarding time and improved consistency in both local and CI environments using JavaScript and package management skills. In flashbots/op-rbuilder, focused on backend reliability by hardening uncompressed block size validation and refining pre-simulation error handling in Rust, ensuring problematic transactions were filtered early and validation logic captured edge cases during external flashblock syncing for greater system stability.
