Work Experience

Software Engineer

Infinite Analytics

Jun 2024 - Present Mumbai, India
  • Reduced geospatial load time from 15 minutes to <1s for multi-million point datasets by architecting a streaming pipeline using PMTiles, Apache Arrow, and Deck.gl.
  • Developed a real-time LLM chat interface with streaming responses and persistent threads using LangGraph, enabling human-in-the-loop workflows for internal tools.
  • Reduced route bundle size by 88% (2.5MB -> 300KB) by eliminating transitive dependency bloat from barrel imports and deferring non-critical components via next/dynamic, improving initial load time.
  • Maintained a React based media analytics platform with ad effectiveness scoring, campaign performance insights and audience segmentation, supporting 2000+ active enterprise users in production.
  • Owned CRA -> Next.js migration, redesigning application state architecture, backend service integration, and AI workflow infrastructure from scratch to support a more scalable product foundation.
  • Offloaded Arrow data processing to Web Workers, eliminating main-thread blocking, streamed viewport-batched geospatial chunks incrementally over WebSockets and integrated Datadog for monitoring.

Full Stack Developer Intern

VC Bay

Apr 2023 - Oct 2023 Remote
  • Built today.green, a carbon management and ESG compliance SaaS platform, from the ground up using React.js and Express.js— shipping interactive emissions dashboards, a supplier data collection system, and a visual supply chain mapping tool built on custom graph rendering logic; improved accessibility by 40%.

Software Developer Intern
