I am specialized in four key domains: 1) Cartography: Transforming data into visually compelling maps that tell powerful stories. 2) GIS/Spatial Analyses: Harnessing the power of geographic information systems for insightful spatial analysis. 3) Remote Sensing Analyses & Photogrammetry: Utilizing advanced techniques to extract meaningful information from remote sensing data. 4) GIS Trainings & Consultation: Empowering individuals and organizations with the knowledge to leverage GIS effectively. I am eager to bring my skills and the collective expertise of my team to contribute to the success of your projects. I look forward to engage in a detailed discussion with you about your project to achieve the best end-results.

I build production-grade GIS, mapping, routing, geocoding, and location-based systems using PostGIS, Django, GeoServer, QGIS, OSRM, Flutter, and modern cloud infrastructure. My strongest area is solving geospatial problems that need more than a basic map dashboard: route engines, reverse geocoding, distance matrices, GPS/location tracking, self-hosted map servers, spatial databases, mobile map apps, and remote-sensing workflows. As Head of GIS at PickMe, Sri Lanka’s leading real-time ride-hailing platform, I designed and delivered core geospatial systems including geocoder, reverse geocoder, POI search, road-network distance matrix, driver-passenger matching, fare modelling, and location-based dispatch support. These systems were built for real production usage with technologies such as PostGIS, OSRM, Tile38, Kafka, Redis, Python, Node.js, and Google Cloud Platform. Over 20+ years, I have delivered software for clients and companies in Sri Lanka, Japan, the USA, and the UAE. My work includes location-based navigation apps, municipal GIS asset-management systems, mapping platforms, AI-assisted SaaS applications, enterprise software, and mobile applications published on iOS and Android. I also run maplk, a self-hosted Sri Lanka vector tile, basemap, and routing server, and I have built real-time SaaS platforms with custom high-performance backend systems. I can help you with: * GIS web applications and dashboards * PostGIS database design, optimisation, and spatial queries * Routing, distance matrix, geocoding, and reverse geocoding * GeoDjango, Django REST APIs, and full-stack GIS platforms * GeoServer, WMS/WFS, QGIS, and ArcGIS-based solutions * GPS tracking, fleet/location systems, and real-time map apps * Flutter mobile mapping applications * Satellite/remote-sensing workflows using Sentinel data and Google Earth Engine * AWS/GCP deployment, Docker, and production handover I hold an M.Sc. in GIS & Remote Sensing and have published research on flood mapping and mitigation.
