Experience
DIGITAL MAP DESIGNER | GOZIO HEALTH
07/2022 - 03/2026
- Designed and maintained over 1,000 digital 3D indoor maps for healthcare wayfinding across hospitals, medical offices, parking structures, and multi-building campuses using JOSM and proprietary 3D rendering software
- Managed the full indoor mapping production lifecycle: CAD plan conversion with precision scaling, multi-floor .osm architecture, XML theme file maintenance for 3D rendering, navigation paths, POI tagging, and web portal content management
- Built a multi-client BLE beacon monitoring pipeline (Python, pandas, REST API, openpyxl) automating battery health reporting across all healthcare clients — replacing a manual per-client CSV process with priority-ranked Excel reports featuring voltage statistics, battery replacement projections, and missing beacon alerts
- Developed mapping automation and QA tools including OSM coordinate extraction, PNG calibration rotation (2D rotation matrix), POI/elevator CSV export, bulk OSM bounds extraction, and an Android ARGB-to-hex color converter
- Authored the company's mapper training guide: a 4-level, 50+ section knowledge base covering JOSM workflows, mapping assets, beacon placement, terminal commands, publishing workflows, and troubleshooting
- Led end-to-end client projects, owning all maps across all sites for multiple clients; collaborated with client success, implementation, engineering, product, and content teams
- Performed QA on all map deliverables, verifying navigation accuracy, 3D render integrity, and overall design consistency before client-facing deployment
