Worked on the AccessAbleNYC repository to deliver advanced map-based routing and location filtering features over a two-month period. Developed and integrated pedestrian and traffic-aware routing using the TomTom API, enhancing navigation reliability and precision for end users. Improved the user interface with React and CSS, introducing a sidebar filter, refined map controls, and accessible options. Hardened error handling for external API responses and optimized performance through code splitting, build tool upgrades, and server-side compression middleware. Leveraged JavaScript and Leaflet.js for interactive mapping, resulting in faster load times, clearer navigation instructions, and a more robust, maintainable codebase for field operations.
