About Me

Open-Source Business Applications · Geospatial Systems Specialist with a passion for building scalable solutions that bridge spatial data and real-world applications.

Professional Journey

I've spent over four decades working with data and technology, and it's been quite a journey. I started back in 1982 as a computer programmer, building business applications with Cobol, CICS, SQL, IMS, and DB2 databases. Those early years taught me the fundamentals of problem-solving through code—lessons that have stayed with me throughout my career.

Over the past eight years, I've focused on geospatial technology and data engineering, working to solve complex spatial data challenges. What began as traditional GIS analysis has grown into something much broader: designing full-stack geospatial systems, building cloud architectures, and creating scalable data pipelines that can handle the demands of modern applications.

What keeps me engaged is the intersection of spatial intelligence and real-world impact. I love taking raw geographic data and transforming it into actionable insights—the kind that help people make better decisions in urban planning, environmental monitoring, and business intelligence. There's something satisfying about seeing data come to life on a map and knowing it's helping someone understand their world a little better.

Professional Focus Areas

Spatial Data Infrastructure

Designing and implementing robust spatial data systems that ensure data integrity, accessibility, and scalability across organizations.

Geospatial Automation

Developing automated workflows and tools that streamline spatial analysis, reduce manual processing, and increase operational efficiency.

Cloud-Native GIS

Architecting cloud-based geospatial solutions that leverage modern cloud services for storage, processing, and visualization at scale.

Data-Driven Insights

Transforming complex spatial data into clear, actionable insights through advanced analytics and interactive visualization.

Technical Approach

My methodology combines systematic problem-solving with pragmatic technology selection:

  • Requirements-Driven Architecture
    Every solution begins with a deep understanding of user needs, data characteristics, and business objectives before any technical design.
  • Iterative Development
    Building in cycles with continuous feedback ensures solutions evolve to meet real-world needs while maintaining technical excellence.
  • Technology Agnosticism
    Selecting tools based on problem requirements rather than personal preference, whether open-source or proprietary solutions.
  • Sustainability & Maintainability
    Designing systems with long-term maintainability, clear documentation, and knowledge transfer in mind.

Current Focus

Django + GeoDjango
Building business applications with a territorial component — workflow management, georeferenced asset inventories, and field data collection tools for public administration.

Ecoturismo Portugal Portal
Developing a curated web mapping portal for hiking and ecotourism routes, with PostGIS backend and Leaflet front-end. Currently in geolocation validation phase.

Statistical Anomaly Detection
Applying expected-value models and Z-score bias engines to detect systematic deviations in human decision-making from historical event data.

Currently Exploring

  • Django REST Framework + HTMX for lean full-stack development
  • GeoDjango spatial queries and geometry serialisation
  • Leaflet.js integration patterns with server-side rendering
  • Streamlit for rapid analytical dashboards
  • Benjamini-Hochberg FDR correction in applied statistical models

Professional Philosophy

"The most elegant technical solutions are those that remain invisible to the end user—seamlessly integrating complex spatial intelligence into intuitive, decision-support tools."
