Paulo Medina

Geospatial Data Engineer

I am an experienced Geospatial Professional with vast experience processing geographic data, developing geospatial models, managing geospatial databases, and creating interactive maps and data visualizations to support global development, environmental initiatives, and business endeavors.

ABOUT ME

I'm a Forestry Engineer completing my M.S. in GIS at the University of Maryland this spring. My career has taken me from forest inventory work to modeling public health indicators across Sub-Saharan Africa—always with one constant: using spatial data to solve problems that matter.

I've worked with multidisciplinary teams across continents, turning messy GPS datasets and survey data into clear insights that inform real decisions. Whether it's mapping health outcomes for local governments or managing geospatial databases for development programs, I'm drawn to work where precision meets purpose.

Currently expanding into cloud infrastructure (training for AWS Solutions Architect certification) to build more scalable geospatial solutions. I'm looking for my next role with organizations that use data and technology to create measurable impact—where the mission is as important as the method.

North Carolina Infant Mortality: Autocorrelation Study

A rigorous statistical analysis of infant mortality patterns across North Carolina. This project moves beyond simple heatmaps to prove statistical significance using global and local spatial autocorrelation metrics.

  • Methodology: Comparative analysis using Global Moran’s I and Getis-Ord G* to identify validated high-rate clusters (Hotspots) in the NE and SE regions.
  • Spatial Insights: Differentiated between "count" vs. "rate" patterns to identify socioeconomic outliers and statistically significant "Low-High" coastal anomalies.
  • Validation: Rejecting null hypotheses via Z-scores and P-value assessment to ensure data-driven public health conclusions.

Lincoln City: Spatio-Temporal Crime Pattern Analysis

A multi-methodological study of auto-theft patterns in Lincoln City, Oregon. This project utilizes hierarchical clustering and moving averages to provide actionable intelligence for law enforcement resource allocation.

  • Clustering: Applied Nearest Neighbor Hierarchical (NNH) spatial clustering across multiple radii to identify 1st and 2nd order crime hotspots.
  • Temporal Modeling: Developed a Spatio-Temporal Moving Average (STMA) to track the geographic "drift" of incidents over time.
  • Comparison: Evaluated NNA vs. NNH to prove why hierarchical structures provide superior operational insights over simple distribution measures.

Web GIS / ArcGIS Experience Builder

A resident-facing web application designed for the City of College Park to promote outdoor engagement. This portal aggregates municipal spatial data into a user-friendly interface, allowing residents to discover parks, trails, and recreational facilities in real-time.

  • Key Features: Interactive filtering by activity type, mobile-responsive design, and integrated routing.
  • Platform: ArcGIS Experience Builder / ArcGIS Online. Impact: Streamlined public access to city amenities and improved digital engagement for the Parks & Recreation department.
