Worked on enhancing observability within the DIMO-Network/devices-api repository by implementing structured error logging for failed disconnection events in Smartcar and Tesla polling services. Focused on backend development using Go, the solution captured critical identifiers such as device_id and integration_id in log entries, enabling more effective debugging and root-cause analysis. By improving the granularity and traceability of logs, the changes supported faster incident response and streamlined troubleshooting for device connectivity issues. The work emphasized robust logging practices and backend reliability, contributing to a more maintainable codebase and facilitating ongoing monitoring and support for disconnection-related events in production environments.
