Public transit agencies, rail engineering consultancies, aviation ground-ops platforms, and maritime AIS vessel-tracking startups frequently search to hire a freelance GTFS / GTFS-Realtime, rail simulation & fleet telemetry programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack Developer and creator of the MRT Jakarta Train Simulation featured on this site.

Core Transit Simulation, GTFS & Fleet Telemetry Capabilities

  • Deterministic Rail & Transit Operations Simulators: Modelling train headways, dwell times, station passenger crowding, signaling blocks, and timetable disruptions in Python/Go and interactive 60 FPS React Canvas/WebGL visualizations.
  • GTFS Static & GTFS-Realtime Protobuf Feeds: Building high-throughput `TripUpdate`, `VehiclePosition`, and `ServiceAlert` Protocol Buffer producers and consumers backed by PostGIS and TimescaleDB.
  • Aviation ADS-B & Maritime AIS Geospatial Tracking: Rendering live global vessel and aircraft trajectories on Mapbox GL / Deck.gl with predictive ETA and geofence alerting.
