Nov 1, 2025November 2025 (mbta/screens) delivered a comprehensive Elevator Status widget upgrade accompanied by targeted quality and stability improvements. The work focused on delivering a more reliable, usable, and scalable rider experience across Pre-Fare screens, with a strong emphasis on correctness, performance, and code quality. Key outcomes include a redesigned Elevator Status widget with improved sorting, station-aware presentation, and UX enhancements; integration of MBTA Go QR codes for direct access to alerts and station views; expansion to support AlertsWidget protocol to reflect live closure data; and a refactor that removed outdated naming while consolidating logic into a single, maintainable widget. In addition, configuration cleanup and code quality improvements reduced memory footprint and tightened safety nets in production. Finally, reliability and correctness were strengthened through targeted fixes to alert presentation and screen refreshing behaviors. This work aligns rider-facing value (clear, fast access to elevator status and alerts) with engineering improvements (robust state handling, better performance, and safer defaults).

Key features were delivered, major bugs fixed, and business value enhanced through architecture changes and UI polish. The team also modernized tooling to speed up releases and reduce toil. Key features delivered: - Alert data model and parsing overhaul with atom-based activity types: consolidates alert facility data via a new Facility struct, centralizes V3 API parsing, and introduces robust string-to-atom mappings to improve alert reliability. - Elevator screen enhancements: uses facility stop data for closures, optimizes route pills, adds downstream context for closed elevators, and improves no-data handling, audio, and UI polish. - Departure API refactor and consolidation (V2): removes legacy v1 code and centralizes departure parsing. - CI/build and tooling improvements: enhances CI workflow, cache handling, ASDF reshims, and webpack adjustments to boost reliability and performance. Major bugs fixed: - Fixed missing alert activity and facility type atoms (prevents runtime atom lookup failures). - Stabilized elevator screen: crash in elevator logic fixed and improved no-data handling and cosmetic issues in closures. - Departure no-data fallbacks and related UI stability improvements. Overall impact and accomplishments: - Increased reliability and correctness of alert data across UI, enabling more accurate rider information. - Smoother elevator closure workflows and reduced maintenance burden by removing dead code and consolidating parsing logic. - Faster, more deterministic releases due to CI/cache and tooling improvements. Technologies/skills demonstrated: - Refactoring, API parsing architecture, and atom-based data modeling. - Data-driven UI improvements for no-data states, audio, and UX polish. - CI/CD optimization (caching, reshims, Webpack) and build tooling improvements. - De-duplication of legacy code and debt reduction for maintainability.
