Tulay — Pedestrian Mobility GIS
01Overview

A data-driven GIS tool that turns open data into a budgeting decision: which streets get pedestrian infrastructure first.

02What I built
  • Glass GIS shell

    Floating data panels over a full-bleed Leaflet map, with a drill-in barangay profile and toggleable transit, hospital and school overlays.

  • Scraped a whole metro

    814 barangays across all 17 NCR cities, joined to OSM transit, hospitals and schools, scored on accessibility, safety and mobility.

  • AI that prioritises

    Grounded LLM calls turn an area's weakest scores into ranked infrastructure actions, with deterministic offline fallbacks.

  • Shipped end to end

    Provisioned and seeded an Atlas cluster, deployed to Vercel with server-side secrets, verified every route in a real browser.
