EXPERIENCE

1. Full-Stack GIS Engineer — Independent Jul 2025 — present

   ’s-Hertogenbosch, Netherlands

   Designing and shipping production Web GIS applications end-to-end — from spatial data architecture to deployed frontend.

   • Built a production spatial web map in vanilla JavaScript, delivering high-performance geospatial interaction without heavy frontend frameworks.
   • Architected and deployed an Oil & Gas GIS platform using vanilla JavaScript, Leaflet, FastAPI, PostgreSQL, and PostGIS supporting spatial queries across boreholes, pipelines, and license boundaries.
   • Operates multiple live GIS applications and portfolio platforms, owning infrastructure, backend services, and frontend delivery end-to-end.
