🗺️ Web GIS Portal

📆 Period: 2024 (approx. 6 months)
🎯 Goal: Create a web platform to display, manage and query geospatial data related to infrastructure and environmental layers, providing user authentication with role-based access and high-performance interactive maps.

🧱 Architecture

Frontend: Angular with interactive maps powered by OpenLayers
Backend: Java (Spring Boot) exposing REST APIs and integrating with a spatial database
GIS Infrastructure: GeoServer configured for WMS/WFS services
Database: PostgreSQL + PostGIS
Authentication: Keycloak for user, role and permission management
Deployment: Kubernetes with custom Helm charts, ingress management and shared namespaces

🚀 My Role

Designed and developed the Angular frontend, including WMS/WFS layer integration
Deployed and fine-tuned GeoServer with advanced styling and filtering
Implemented REST APIs and PostGIS queries for spatial operations (bounding box, thematic layers, etc.)
Integrated Keycloak for federated authentication and role-based access control
Optimised system performance through caching strategies and spatial indexing

💡 Key Challenges Solved

Coordinated dynamic layer rendering with complex spatial queries
Managed user-specific views and access restrictions per dataset
Reduced spatial-query response times using materialised views
