Douglas Greenshields

David Greenshields developed core features for the communitiesuk/epb-ecaas-frontend repository, focusing on cross-platform desktop support and robust API integration. He introduced Tauri-based scaffolding to enable a unified desktop client, leveraging Rust and TypeScript to establish a maintainable project structure. David integrated the Home Energy Model crate for automated FHS calculations, streamlined API access token management to enhance security and reduce boilerplate, and improved type safety with targeted tests and refactors. His work also addressed user experience issues in CodeYourFuture/curriculum, using JavaScript and web components to prevent unwanted navigation, demonstrating depth in both backend and frontend engineering.

August 2025 monthly summary: Focused on UX stability and type-safety improvements across two repos, delivering targeted fixes and refactors that reduce risk and improve maintainability. Key outcomes include 1) CodeYourFuture/curriculum: prevented accidental navigation gestures during horizontal scroll by introducing isScrollingHorizontally state and a helper to detect horizontally scrollable targets; commit 9756ca8e80bcdffec46797194b22d8225e7666eb. 2) communitiesuk/epb-ecaas-frontend: added tests verifying PageId union coverage and refactored pvAndBatteries.ts to use string literals for page IDs with a type assertion for pvAndBatteriesPages; commit d234a673f3e8b8799188f37602b17e23ebd0f5ce. The overall impact: reduced UX drift from unintended navigation, improved type safety and test coverage, and stronger foundations for future refactors.
