Experience

Remote

• Architected a multi-tenant geospatial Java backend with JWT-based workspace isolation, PostGIS metadata storage, automated GeoServer REST publishing, and Cesium-ready search APIs supporting keyword, bbox and proximity queries.
• Built the GeoTwin Ecosensor Plugin: a digital-twin backend integrating 12 external data sources, ingesting hourly air quality data for around 600 CAAQMS stations and streaming physics-based sensor simulations to a live browser dashboard over WebSocket.
• Engineered a geospatial InSAR pipeline (Sentinel-1 GeoTIFF → PostGIS point cloud → FastAPI MVT tile server) serving real-time ground deformation data across multiple Indian regions via a MapLibre GL JS frontend.

Remote

• Blockchain security and fraud detection research under the Ethereum Protocol.
• Dataset curation, fund-flow analysis and real-time malicious activity prediction.
• Applied machine learning and graph neural networks (GNNs) to fraud detection challenges.

Remote

• Developed the backend for NFT-based services with 100s of concurrent users.
• Led multiple client projects with a team of 5 and retained clients for the company.
• Implemented security features for safe Testnet transactions for early Idriss users.
