Nasiru Adebayo O.

I’m a Senior Geospatial Engineer specializing in PostGIS, spatial APIs, Web GIS, and geospatial data infrastructure. I build production-grade geospatial systems not merely maps. My recent work includes: 1. engineering a vector-tile mapping platform serving 500K+ monthly users and 65M+ API calls per month 2. designing APIs for 80,000+ points of interest 3. delivering a statewide World Bank–supported enterprise GIS serving a population of 3.2M+ across all 16 local government areas. I help companies build and scale products involving: 1. Spatial databases & APIs: PostGIS, PostgreSQL, REST APIs, spatial querying and optimization 2. Web GIS applications: interactive maps, spatial search, data editing and location-based applications 3. Vector-tile infrastructure: PMTiles, Tippecanoe, MapLibre and high-performance map delivery 4. GIS backends: FastAPI, Django/GeoDjango, GeoServer and spatial services 5. Geospatial data pipelines: OSM, Python, GeoPandas, GDAL and automated spatial processing 6. Routing & location intelligence: spatial analysis, network data and routing workflows Why clients hire me A performant geospatial application starts with sound data architecture. I am meticulous about database design as I understand that a carefully designed database is the cornerstone of performance and scalability. This is where I bring particular value. I’m particularly well suited to projects involving very large spatial datasets, high-traffic Web GIS platforms, spatial APIs, PostGIS, vector tiles, OSM and complex geospatial data pipelines. If you're building a serious geospatial product or need an experienced engineer to solve a difficult spatial-data problem, let's talk.
