Developed a YAML-based template for OMIE day-ahead electricity prices in the evcc-io/evcc repository, enabling users to select between Portuguese and Spanish market data. The work involved designing a flexible template structure and implementing parsing logic to accurately process quarter-hourly pricing, supporting real-time visibility for both markets. By integrating API data and modeling market information, the solution reduced manual configuration and improved pricing accuracy for end users. The approach demonstrated skills in YAML templating, data parsing, and template design, while addressing the specific requirements of electricity pricing in Portugal and Spain. No major bugs were reported during this development period.
