FullStack GIS Developer: Custom Web Apps and Spatial Databases
Stati Uniti
Inglese
Chi sono
GIS developer with ten years of experience building enterprise geospatial systems for mining, utility, energy, and environmental clients. I build custom web applications in ArcGIS Enterprise and Experience Builder, automate geoprocessing workflows with Python/ArcPy, and design spatial databases in PostGIS and SQL Server. Full-stack when the project calls for it, with TypeScript/React frontends and cloud infrastructure on AWS. I run my own consulting practice out of Houston while building a geospatial SaaS platform for site suitability analysis. Project code at github.com/matthew-lottly.
