Software engineer at Dream11.

I've spent 2.5+ years at Dream11 and Headout, working on experimentation platforms, design systems, and checkout flows. Most of my work is on the frontend, with some backend work too.

I'm interested in runtime internals and developer tools. I often build small projects to understand how things work.

D11 Platform

Oct 2025 - Present
  • Built the D11 experimentation platform: audience targeting, feature flags, and phased rollouts on React Web and React Native for 100M+ users.
  • Wrote an SDK that queues events in memory, batches uploads, retries with exponential backoff, and saves offline events in IndexedDB. Gzip through CompressionStream reduced payload sizes by 60–80%.
  • Standardized the frontend design system and wired up Figma-to-code workflows; cut CSS work by 30–40% across several squads.
