Yuli Ferna worked on the XLabs/portal-bridge-ui repository, focusing on the deprecation and removal of Aptos Network support across mainnet, testnet, and USDC bridge configurations. Using TypeScript and applying configuration management and frontend development skills, Yuli executed a comprehensive cleanup of configuration schemas and eliminated Aptos-specific code paths. The work included end-to-end validation and regression testing to ensure the stability of remaining networks, as well as updates to documentation and tests. This targeted feature reduced the maintenance surface and security risk, aligning the product with current network strategy and demonstrating a methodical approach to technical debt reduction.
