System Optimization

I am a Senior Research Developer with over 5 years of experience building scalable GIS platforms, 3D geospatial visualization systems, and enterprise-grade applications.

Currently at Heliware, I lead the development of Bhumi — a production-grade 3D GIS platform designed for real-time terrain analysis, spatial intelligence, and defence operations.

My work focuses on performance engineering, where I have delivered significant improvements including 3× rendering optimization, 10× mobile performance gains, and large-scale data processing enhancements using async pipelines and WebSockets.

I have collaborated with organizations like DRDO and enterprise clients to build high-impact geospatial intelligence tools under strict performance and reliability constraints.

Beyond development, I actively contribute to innovation through research-driven engineering, including creating reusable tools like bhumi-sdk for web-based 3D GIS operations.

I am passionate about solving complex spatial problems and building systems that push the boundaries of web-based 3D and geospatial technology.
