Indoor Wayfinding at Gozio

I'm a digital map designer specializing in indoor wayfinding, having spent four years at Gozio Health creating interactive 3D maps for healthcare systems across the United States. What draws me to indoor mapping is the balance between art and science — where aesthetics and spatial precision are equally essential to making a map that actually works for the people navigating it.

Beyond map design, I cross-trained in QA, content management, and geospatial tool development, which gave me a fuller picture of the wayfinding lifecycle and led me to build internal automation tools that streamlined workflows for the whole team.

About Me

Bio

GIS professional with nearly 4 years of experience in indoor mapping, cartographic design, QA, data analysis, and geospatial tool development. Designed and maintained over 1,000 digital indoor maps for healthcare wayfinding. Experienced in the full mapping lifecycle — from CAD plan processing and 3D rendering to navigation, QA, and content management. Developed Python automation tools for mapping workflows and data analysis/monitoring.

Education

Bachelor of Science in Applied Geography, Geospatial Technologies Aug 2018 – Dec 2023 University of Louisville

Thesis: Flood impact, frequency, and hydroclimatological analysis of the July 2022 Eastern Kentucky flood event — spatial analysis and hydrological modeling of Whitesburg, KY
Coursework: Remote Sensing, Spatial Statistics, Web GIS, Cartographic Design, Database Design, Hydrology, Python for GIS

Experience

Digital Map Designer Jul 2022 – Mar 2026

Gozio Health

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
