During February 2026, Ndemie developed a feature for the evcc-io/evcc repository to enhance energy price reporting for the Netherlands. The work focused on supporting optional energy tax and provider charges within the pricing module, clarifying that prices include these charges by default and updating rendering logic to subtract them when configured. This approach addressed double-counting issues and improved reporting accuracy for NL customers. Ndemie applied backend development and data processing skills, utilizing Go and YAML to implement the changes. The emphasis on correctness and traceability contributed to clearer business decisions and a smoother rollout, reflecting thoughtful engineering depth.
