Developed dynamic validator change management and enhanced configuration capabilities for the Ethernal-Tech/apex-bridge and blade-apex-bridge repositories. Focused on backend and blockchain integration, the work introduced a CLI command for validator updates, an oracle contract to track change status, and improved API endpoints for status retrieval. Leveraging Go and Ethereum smart contract interaction, the implementation emphasized reliability through refined parameter handling and code quality improvements. Additional contributions included a new configuration generation flag and expanded smart contract bindings, streamlining bridge administration. The approach prioritized automation, operational risk reduction, and seamless integration, reflecting a strong foundation in API and backend development.
