I will build a spatial database and rest api with postgis and python fastapi

Need a spatial backend that handles real geographic data at production scale?

I'm a geospatial systems engineer with production experience on enterprise GIS platforms (PETRONAS PiriGIS, PLUS Berhad, Government of Sabah, DOE/JAS). I design PostGIS databases and REST APIs that are fast, correct and maintainable.

WHAT I DELIVER

- PostGIS schema design (geometry types, SRID, spatial indexes)

- Spatial queries: proximity, intersection, buffer, nearest-neighbour, routing

- REST API with FastAPI or Flask, fully OpenAPI-documented

- Data ingestion from CSV, shapefile, GeoJSON, WFS or existing databases

- Docker setup + deployment notes

TECH STACK

PostgreSQL / PostGIS, Python (FastAPI, Flask), SQLAlchemy / GeoAlchemy2, Docker, Azure.

WHY ME

- Real production spatial backends, not tutorials

- Correct SRID and indexing decisions from day one

- Clean, documented, reproducible code

Send me your requirement (data, queries, users) before ordering and I'll confirm scope and timeline.
