TB Copters Fleet Portal – Geospatial GIS & Autonomous Flight Operations

Enterprise flight operations, geospatial GIS, and fleet dispatch platform engineered for commercial agricultural drone fleets. Architected the core Laravel REST API backend with MySQL Spatial extensions and Pusher WebSockets to coordinate live pilot tracking, autonomous flightpaths, and biocontrol supply chain logistics across European farmland.

Executive Overview & Key Engineering Deliverables
  • System Architecture: Robust Laravel REST API paired with MySQL Spatial extensions (Points, LineStrings, Polygons) and spatial indexes for multi-region farm boundary mapping.
  • Autonomous Trajectory Engine: Custom geometric solver calculating discrete swath flightpaths, mission acreage, and sub-meter Trichogramma biocontrol capsule drop waypoints.
  • Real-Time Telemetry & AI: Pusher WebSocket pipeline streaming live pilot GPS coordinates under 200ms latency, integrated with a TypeScript Model Context Protocol (MCP) server for autonomous flight dispatching.
  • Business Impact: Boosted commercial flight dispatch efficiency by 40% across European farms while automating German municipal police flight clearance workflows.
