GraphHopper Routing Engine - Turn Instructions & Data Parsing
Java / OSM DataRe-architected the turn instruction fallback cascade to prioritize OpenStreetMap destination tags over internal road references. Resolved a legacy data inheritance leak that caused unnamed roundabout exits to incorrectly adopt the roundabout's name, ensuring accurate real-world navigation guidance.
GraphHopper Routing Engine - Core Routing & Algorithms
Java / Graph AlgoEngineered geometry-based fallback algorithms and dynamic angle thresholds to override flawed speed-based instruction suppression, resolving critical navigation failures at complex Y-forks and motorway exits. Refactored legacy instruction logic to accurately generate "Keep Left/Right" and "Turn slight" commands.
