April 2025 focused on stabilizing core dependencies and enabling advanced optimization capabilities in the sostrades-optimization-plugins repo, delivering reproducible builds and color math-enabled optimization.

March 2025 monthly summary focusing on key accomplishments, major bug fixes, and value delivered across core and optimization plugins.

February 2025: Delivered key features across two repositories with strong emphasis on analytics UX, data ingestion robustness, and UI clarity. Major features include Advanced Plotting Customization and UX for Plotly charts (axis control, range slider, subtitles, and improved title/tick formatting) and DifferentiableModel API enhancements (dynamic outputs and recursive handling of nested inputs). UI labeling improvement for StartSOSTRadesGUI to Auto relaunch. While no explicit bug fixes were logged in the data, testing for complex inputs increased resilience. Overall, these changes improve business value by enabling more flexible analytics, easier workflow management, and more reliable data processing. Technologies demonstrated include Plotly, Python class architecture for DifferentiableModel, recursive/dynamic input handling, and test-driven validation.

January 2025 across the os-climate repos focused on delivering robust visualization capabilities, foundational modeling enhancements, and strong code quality improvements to drive clearer data storytelling, reliability, and faster delivery of business insights.

December 2024 monthly summary for os-climate development focused on delivering accurate CO2 accounting, enhanced cross-scenario analytics, and robust data visualization. Key outcomes include a corrected gradient-based CO2 emissions calculation in fossil gas and refinery disciplines; new GDP vs energy production visualizations for multi-scenario post-processing; integration of final energy consumption data into the IEA NZE analysis to align consumption with GDP visuals; introduction of an EnhancedColorMap to support accessible, consistent color palettes; and strengthened data handling and tests for chart generation and energy data preparation.

November 2024 performance: Delivered targeted features and bug fixes across two repos to improve data accuracy, cost estimation, and code quality, enabling more reliable scenario planning and cost modeling for business decisions. Key outcomes include NZE scenario data accuracy improvements in witness-core; accurate resource cost calculation and double-counting fix in witness-energy; wind investment data mapping bug fix; code quality improvements; and header metadata corrections. These changes enhance data fidelity, reduce calculation errors, and improve maintainability, delivering measurable business value.
