Summary

Geological engineer with 13 years at PDVSA (Venezuela and Ecuador, 2005–2018) in sedimentology, stratigraphy, and subsurface interpretation — including field-development spatial databases and geologic mapping in ArcGIS (used through ~2012). Retraining into software since 2022 via three part-time bootcamps and a portfolio of personal projects; since 2025 focused on web GIS, building with Python, FastAPI, Leaflet, and PostGIS.
