This repository serves as an entry point to my work around geospatial systems, focused on interoperability, open standards, and scalable architectures.

I work primarily on building and integrating geospatial systems using open source technologies, with an emphasis on:

• OGC standards (WMS, WFS, WFS-T, OGC API)
• Spatial data pipelines and transformation
• Web-based geospatial applications
• Interoperability between services and platforms

• Backend: Python, Django, PostGIS
• Geospatial servers: GeoServer, GeoNode
• Data processing: GDAL/OGR
• Frontend: OpenLayers (with Vue / Quasar)
• APIs: REST + OGC services

Exploration of flexible API patterns as alternatives or complements to traditional WFS services, including:

• Advanced querying (filters, grouping, aggregation)
• Direct GeoJSON delivery from PostGIS
• Controlled exposure of spatial data via API layers

Practical implementation and extension of:

• WMS for visualization
• WFS / WFS-T for data access and editing
• Early adoption of OGC API (Features / Processes)

Including real-world challenges such as:

• Authentication (OAuth2 / OIDC)
• Permissions and access control
• Interoperability between clients and servers

Work around geospatial processing pipelines, including:

• Integration with WPS engines like ZOO-Project
• Automation of spatial workflows
• Data transformation using GDAL

Development of interactive geospatial applications using:

• OpenLayers for map rendering
• Vue / Quasar for UI
• Integration with backend geospatial services

Including:

• Field data capture interfaces
• Visualization of spatial datasets
• Vector tiles (MVT) and performance optimization

Design of modular and decoupled geospatial systems:

• Separation of concerns between API, data, and rendering layers
• Hybrid architectures (server + client-heavy)
• Exploration of lightweight alternatives to monolithic stacks

I have contributed to the geospatial open source ecosystem through:

• Issue reporting and validation
• Technical discussions and support
• Pull requests and small improvements

Including contributions to projects such as:

• ZOO-Project (WPS implementation)
• Other GIS-related repositories

• OGC API adoption and implementation
• Flexible geospatial APIs beyond traditional standards
• Processing services exposure (OGC API - Processes)
• Optimization of geospatial data delivery (MVT, APIs, pipelines)

This is an evolving set of projects and experiments around real-world geospatial problems, particularly focused on practical implementation rather than theoretical approaches.
