During March 2026, John Auricchio enhanced energy reporting accuracy for the evcc-io/evcc repository by refactoring the OpenEVSE energy calculation logic. He reworked the backend in Go to source session and total energy values directly from the API response, improving the correctness and reliability of reported data. This approach aligned computed energy data with actual API outputs, reducing discrepancies and supporting more accurate billing and user trust. John also addressed API consistency and key handling, streamlining integration and reducing misreporting risks. His work demonstrated depth in API development, backend engineering, and data handling, resulting in maintainable and testable code improvements.
