Jesper Cejie developed and refined core features for the Sustainable-Action-Foundation/eco-planner repository, focusing on robust data input, accessibility, and internationalization. Over three months, Jesper overhauled the DataSeriesInput component using React and TypeScript, introducing semantic HTML, dynamic year-based rendering, and toggleable input tables to enhance usability and accessibility. He improved API integration and localization, expanded translation support, and optimized UI/UX through responsive CSS modules and performance enhancements. Jesper’s work included extensive code cleanup, modularization, and documentation, resulting in a maintainable codebase. His engineering addressed evolving data requirements and ensured the application remained reliable, user-friendly, and globally accessible.

May 2025 monthly summary focused on delivering a feature-rich DataSeriesInput overhaul for eco-planner with strong accessibility and UI improvements, plus targeted code cleanup to boost maintainability and future extensibility.

April 2025 monthly summary for Sustainable-Action-Foundation/eco-planner: Key features delivered spanned localization and UI/UX improvements, performance enhancements, and data-series tooling. Localization improvements included expanded translations, translation markup adjustments, and non-breaking hyphen handling, with added translations to query builder components and API language warnings to improve global usability. Performance and UX enhancements included faster table selection, a safe cap on concurrently rendered API tables, and refinements to dialog sizing and visibility controls in the query builder. Data-series capabilities were advanced via consolidating DataSeriesInput and BaselineDataSeriesInput into a single DataSeriesInput component, plus new data-series grid controls and baseline data support. Code quality and maintenance saw broad cleanup, removal of unused imports and debugging timers, optional chaining, and DOM usage reductions to improve testability and future maintainability. Major bug fixes included translation rollback to restore expected behavior, decimal point entry fix for numeric inputs, ability to remove a custom baseline, and a fix ensuring the selected table label displays correctly on the second slide.
