Contributed to the evcc-io/evcc repository by building and refining backend features focused on pricing data ingestion and vehicle communication. Developed a robust pipeline for retrieving and parsing pricing data, implementing ZIP archive handling and XML processing in Go to ensure accurate daily rate calculations. Enhanced reliability by updating API endpoints, stabilizing data retrieval, and improving error handling for both pricing and Renault vehicle integrations. Addressed edge cases in file parsing and JSON payloads, reducing runtime errors and support incidents. Demonstrated proficiency in API integration, backend development, and data parsing, delivering solutions that improved data fidelity and system stability.
Monthly work summary for 2025-10 focusing on business value and technical robustness. Implemented a robust ZIP tariff file detection in the Pun module to ensure Prezzi.xml is loaded from tariff archives, improving reliability when archives contain additional metadata. This fix reduces misloads, improves tariff accuracy for users, and strengthens the tariff loading path.

June 2025 monthly summary for evcc: Stabilized Renault Kamereon API handling to improve reliability in Renault integration. Implemented robust handling for incomplete JSON payloads by initializing the Programs field as an empty slice of interfaces in the Kamereon API, preventing panics and flaky wakeup behavior in MY24 deployments. This change reduces runtime errors during wakeup flows and enhances overall vehicle compatibility.
