Worked on enhancing PulseChain Mainnet integration within the argotorg/sourcify repository by delivering a feature that added multiple RPC URLs, including trace-enabled endpoints, to the configuration. Focused on backend development and API integration, the work involved resolving JSON formatting issues in sourcify-chains-default.json to prevent parsing errors and improve system stability. These improvements increased the reliability and observability of PulseChain connectivity, enabling faster diagnostics and reducing potential downtime. The changes were documented with commit references to support production readiness for multi-RPC configurations, demonstrating a methodical approach to backend reliability using JSON and API integration skills over the course of the month.
