Worked on the phantom/wallet-sdk repository to enhance release workflow stability and modernize frontend dependencies. Addressed release reliability by pinning the changesets GitHub Action to a fixed extended hash, ensuring deterministic builds and safer rollbacks through improved traceability. Upgraded React and Next.js to their latest minor versions, reducing technical debt and aligning with semantic versioning for better compatibility and maintainability. Focused on CI/CD automation and front end development using JavaScript and YAML, with an emphasis on reproducible releases and streamlined upgrade processes. The work prioritized traceable, auditable changes and future-proofed the repository’s core frontend libraries for ongoing development.
