GIS Analyst • Remote Sensing • Web Mapping • GeoAI

Transforming geospatial data into decision-ready maps & dashboards.

I’m a GIS & Remote Sensing specialist with 8+ years of hands-on experience across cartography, spatial analytics, and GeoAI. I help planners, engineers, and researchers answer where and why—from land-use change to transportation insights.

FAQ

What projections do you prefer?

I choose projections per task: equal-area for thematic maps (e.g., EPSG:6933), conformal for navigation/angles (UTM where appropriate), Web Mercator for web maps.

Do you deliver reproducible pipelines?

Yes—documented notebooks or scripts (Python/SQL), versioned data schemas, and makefiles for repeatable runs.
