Chang Ge focused on code hygiene and bug resolution across the axelarnetwork/axelar-core and DefiLlama/defillama-app repositories, emphasizing maintainability over new feature development. In axelar-core, Chang removed a duplicate abci package import, addressing potential compile issues and streamlining the codebase for future backend work in Go. For the DefiLlama app, Chang corrected a naming inconsistency in comments, aligning documentation with the actual TypeScript function logic to improve clarity for React-based front end development. This work reinforced cross-repository code quality, reducing confusion and technical debt, and demonstrated a methodical approach to maintaining robust, readable code in both backend and frontend contexts.
