/about_me

Professional Summary


Backend Engineer focused on building resilient microservices and event-driven systems. When I'm not untangling routing algorithms for open-source engines, I'm orchestrating Spring Boot and Kafka, or tinkering with hardware integrations. I build software that scales, and occasionally, a 404 page with a cat on it.

GraphHopper Routing Engine - Turn Instructions & Data Parsing

Java / OSM Data

Re-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.

"Because 'toward Euskirchen' is infinitely better than 'onto Magic Circle'."
View PR #3315

GraphHopper Routing Engine - Core Routing & Algorithms

Java / Graph Algo

Engineered 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.

"Because getting lost on a motorway is sub-optimal."
