Over six months, contributed to the evcc-io/evcc repository by building and stabilizing data ingestion and pricing features for electric vehicle charging systems. Developed robust API integrations and backend logic in Go, focusing on reliable retrieval and parsing of pricing data from ZIP and XML sources. Enhanced vehicle communication by implementing remote wakeup controls for Renault E-tech models and improved error handling for incomplete JSON payloads. Addressed data pipeline reliability by refining tariff file detection and ensuring resilience against missing or malformed external data. The work emphasized backend development, file parsing, and error handling, resulting in reduced support incidents and improved data accuracy.

Apr 1, 2026April 2026 — Focused on stabilizing data ingestion and tariff logic in evcc. Implemented resilience for missing next-day data to prevent ingestion outages and ensure tariff calculations continue to operate. Fixed PUN tariff path to tolerate absent next-day data (commit 884f1834f9ecbbab8a9866bfd9167e0206f68737). This work demonstrates Go-based data pipeline resilience, robust error handling, and overall reliability improvements with tangible business value: reduced downtime and more accurate tariff decisions.

Oct 1, 2025Monthly 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.

Jun 1, 2025June 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.
