I will build postgis spatial databases and geospatial apis for your map applications
M.Muddasir
About this gig
Is your map app slow? Are you storing location data as plain latitude/longitude columns and facing performance issues at scale?
I design and build production-grade spatial databases using PostgreSQL and PostGIS the industry standard for geospatial data storage, querying, and analysis.
WHAT I BUILD
- PostGIS database setup and spatial schema design
- Radius searches find points within X km
- Bounding box and polygon intersection queries
- Distance calculations using geography(Point)
- GiST spatial indexing for faster queries
- GeoJSON REST APIs for map applications
- Large dataset optimization (100K+ features)
- GeoJSON, Shapefile, KML, and CSV processing
- WFS/WMS integration with GeoServer
- Vector tile generation for Mapbox and MapLibre
- Spatial joins and geospatial analysis
- PostGIS functions area, centroid, buffer, and union
Whether you're building a new mapping application or optimizing an existing one, I can help you achieve fast, reliable, and scalable geospatial performance.

Senior GIS Engineer & Full-Stack Developer with 6+ years Specialized in Mapbox, Leaflet, Google Maps, MapLibre, and PostGIS. I've shipped production GIS systems across real estate, agriculture, energy, and logistics.
MY STACK:
Maps: Mapbox GL JS · MapLibre GL · Leaflet · Google Maps API
DB: PostgreSQL · PostGIS · GeoServer
Web: Next.js · React · Angular · TypeScript · Node.js · Go
Data: GeoJSON · WFS · WMS · Vector Tiles · Shapefiles
I work full-time as a GIS engineer, maps are my main work, not a side skill.
Message me before ordering, let's make sure I'm the right fit for your project.

FAQ
My app already uses lat/lng columns, can you migrate it to PostGIS?
Yes. I'll convert your existing columns to PostGIS geometry types, add spatial indexes, and rewrite your queries — all without data loss
Can you work with existing databases or only new projects?
Both. I can audit and optimize an existing schema or design a new one from scratch.
What if I have a large dataset, CSV or Shapefile with 100,000+ records?
That's where PostGIS shines. I'll import, index, and optimize it for fast spatial queries regardless of size.
Do you provide the database or do I need my own server?
You'll need your own database, I recommend Neon or Supabase for easy managed PostgreSQL with PostGIS support I'll guide you through setup.
Can you build the API too, not just the database?
Yes — the Standard and Premium packages include a full GeoJSON REST API ready to connect to your Mapbox or Leaflet map.
