Aldian Fazrihady adalah Programmer Freelance Senior, Full Stack Developer, dan AI Application Engineer (Profil Upwork | Direktori Lengkap 410+ Panduan Programmer Freelance).
Delivery networks, store locators, transit trackers, real estate portals, and IP intelligence platforms rely on fast, accurate geospatial queries: radius proximity searches, polygon geofencing, route interpolation, and live vehicle tracking.
If you want to hire a freelance geospatial, PostGIS, GeoDjango, and interactive map programmer, I am Aldian Fazrihady—creator of both the MRT Jakarta Real-Time Traffic Simulation and Find IP Location.
Geospatial Engineering Stack I Deliver
1. Sub-10ms Proximity & Polygon Queries with PostGIS GiST Indexes
Computing Haversine distances in application memory or running unindexed latitude/longitude scans cripples database performance. I build spatial schemas using PostGIS geography(Point, 4326) columns, GiST spatial indexes, and ST_DWithin / ST_Contains queries (GeoDjango & PostGIS Nearby Shop API).
2. Interactive Mapbox GL, Leaflet & Canvas Telemetry Rendering
On the frontend, I build smooth 60fps interactive maps in React with clustered markers, GeoJSON choropleth layers, and live vehicle coordinate interpolation.
3. IP Geolocation & Regional Routing Pipelines
I integrate MaxMind GeoIP2 / GeoLite2 CIDR blocks with PostgreSQL gist (network inet_ops) indexes for sub-millisecond IP-to-location lookups and regional compliance routing.
