Full-Stack Geospatial Web Architecture
Web GIS transforms standalone spatial analyses into interactive, multi-user web applications accessible directly in modern web browsers. My approach focuses on creating modular three-tier architectures consisting of a robust spatial database, a standards-compliant map server, and a lightweight client interface connecting with GIS spatial data engineering.
By implementing Open Geospatial Consortium (OGC) specifications (WMS, WFS, WCS) and modern Vector Tile (MVT) protocols alongside Python geospatial data processing, I build spatial platforms capable of streaming thousands of features with minimal latency.
Web GIS Core Pillars & Competencies
Spatial Database & PostGIS
Storing geometric geometries in PostgreSQL with GiST indexes. Executing high-speed bounding-box queries, spatial intersections (ST_Intersects), and generating dynamic Mapbox Vector Tiles (ST_AsMVT).
GeoServer & OGC Web Services
Managing workspaces, data stores, and layer publishing. Authoring Styled Layer Descriptors (SLD) for rule-based thematic symbology and configuring GeoWebCache for rapid raster tile caching.
Interactive Frontend Clients
Developing dynamic web maps using Leaflet.js, Mapbox GL JS, and React-Leaflet. Features include dynamic layer toggling, choropleth rendering, popup telemetry summaries, and custom coordinate measurement tools.
Spatial REST APIs & Docker
Building Node.js / Express and Python / FastAPI microservices to serve GeoJSON payloads. Containerizing GIS stacks with Docker Compose for consistent, scalable cloud deployment.
LocalIt: Hyperlocal Delivery & Spatial Routing Platform
Implemented location-based services integrating Google Maps API, real-time Socket.IO socket connections, and spatial boundary checking for a 3-sided mobile delivery application.
