About Me

Hello! I'm Jonnier Salaverria, a Full Stack Developer specialized in GIS and geospatial systems. I build complex platforms for fiber optic network management, territorial analytics, and cartographic visualization.

Self-taught and driven by curiosity, I work with React, TypeScript, Node.js, and Python across the full stack. My focus is on Clean/Hexagonal Architecture, multi-database integration (PostgreSQL, SQL Server, Elasticsearch), and delivering production-ready systems with Docker.

I've built everything from real-time map viewers with MapLibre and Deck.gl to predictive models with Scikit-learn, geocoding services with FastAPI, and horizontally-scaled GeoServer clusters. Currently delivering end-to-end solutions for Worldwide clients.
