In May 2025, Cas Raw focused on stabilizing wallet connectivity for the KomodoPlatform/coins repository by addressing persistent issues with Electrum server URLs and WebSocket port configurations. Through targeted debugging and backend development, Cas identified and corrected misconfigurations that had disrupted real-time updates and user access. Leveraging skills in API integration, network configuration, and JSON, Cas delivered precise patches that restored reliable server communication and reduced user-reported incidents. The work did not introduce new features but laid a solid technical foundation for future enhancements, demonstrating a methodical approach to problem-solving and a strong grasp of backend connectivity challenges.
