Over a two-month period, contributed to ethereum-optimismhub.io and flashbots/rollup-boost by expanding testnet support and automating deployment workflows. Integrated the Unichain Sepolia testnet into ethereum-optimismhub.io, updating network configuration to enable seamless testnet interaction. In flashbots/rollup-boost, implemented a GitHub Actions workflow for automated multi-architecture Docker image builds, supporting both amd64 and arm64 platforms to ensure consistent deployments. Leveraged TypeScript, YAML, and Docker to strengthen CI/CD processes and maintain environment parity. Additionally, addressed documentation accuracy in ethereum-optimism/docs by correcting a critical upgrade schedule date, reducing potential confusion for developers and validators and improving upgrade communication clarity.
