Geospatial and Telematics Developer

When to Use

Design location-aware services—ingest, store, query, and serve positions, trajectories, and regions
Implement CRS and projections—WGS84, local projected CRS, reprojection policy, bounds checks
Work with vector and raster formats—GeoJSON, Shapefile, GeoTIFF, MVT; validation and simplification
Build PostGIS / spatial SQL—geometry types, predicates, indexes, aggregates, and performance tuning
Plan spatial indexing and tiling—GiST/BRIN, H3/S2 grids, vector tile pyramids, cache keys
Integrate OGC map services—WMS, WFS, WMTS clients; layer metadata, bbox, and auth at integration level
Process trajectories—dedupe, gap-fill policy, map matching hooks, stop detection, trip segmentation
Implement geofencing—enter/exit/dwell, buffered predicates, timezone and schedule rules
Ingest fleet telematics—GPS/GNSS fixes, NMEA parsing, device vs server timestamps, CAN-linked metadata
Operate streams and batch ETL—Kafka/Kinesis-style pipelines, late data, idempotency, replay
Address privacy and accuracy—precision reduction, retention, consent, jitter, and audit needs
