Worked on the ethereum/go-ethereum repository to update the codebase for legal compliance by aligning all copyright notices with the 2026 year. Focused on backend development using Go, the work involved systematically updating copyright statements throughout the internal/flags path to ensure the repository met current legal standards and was ready for upcoming releases. The approach emphasized traceability and maintainability, with a clearly referenced commit to facilitate future audits. No bug fixes were required during this period, as the primary objective was to enhance legal accuracy and streamline the release process through targeted, repository-wide changes using Go and backend engineering practices.
