During June 2025, work centered on backend development and data handling within the electricitymaps-contrib repository, specifically addressing a critical bug affecting geographical coordinate integrity. The developer identified and resolved an issue where longitude and latitude values were reversed in the data pipeline, which had the potential to cause inaccuracies in location-based features and downstream analytics. Using Python, they implemented a targeted fix that corrected the coordinate processing logic, ensuring reliable data for all dependent systems. The approach included thorough code review and focused testing to validate the solution, ultimately enhancing the robustness and accuracy of location data without introducing new user-facing features.
