I build Python backend systems for geospatial data, climate risk analytics, distributed processing, and high-performance APIs.

From March 2021 to May 2026, I worked at Intensel Ltd as a Software Engineer focused on backend and data infrastructure. I owned architecture, delivery, distributed processing, and production support for a climate risk platform used by enterprise customers across 10+ countries.

Feel free to reach out and say hi on X or LinkedIn . I'm always happy to connect, collaborate, and share knowledge.

Projects

Climate Risk Platform
Owned backend architecture and delivery for an enterprise climate risk platform serving customers across 10+ countries, from requirements and technical design through rollout and production support.
Natural-Language Geospatial Analytics
Built an LLM-powered agent that converted natural-language requests into structured geospatial and analytics queries, using DuckDB for vector-data analysis and integrating with backend APIs and PostgreSQL/PostGIS.
Global Building Footprints
Built ingestion, validation, indexing, and query workflows for 2.3B+ building records across 1.8 TB of PostGIS data, balancing batch throughput with low-latency access.
Map Tile Service
Designed authenticated backend delivery for 5.3 TB of geospatial raster data, with tuned storage access, caching, logging, and monitoring for reliable production delivery.
RediServe
Built an asynchronous HTTP API for Redis in Rust with Axum and Tokio, using connection pooling and explicit backend resource management.
