About

Six years in growth and performance marketing: paid media at scale, acquisition funnels, product launches across India and Bermuda. Somewhere in that work, I kept hitting the same wall: platform data couldn't be trusted. Every channel claimed credit. ROAS looked great on the dashboard and flat in reality. That question, how do you actually measure what works, is what pulled me toward analytics.

I'm also a builder. Started Caroma Fragrance from scratch in India, currently building an AI journaling product for mental health at UMD's Xfoundry accelerator. The 0-to-1 problem is the one I find most energising.

Now completing an M.S. in Marketing Analytics at UMD Smith, doing HMM retention research and building Bayesian MMM in Google Meridian. Trying to combine six years of campaign intuition with the statistical rigour to actually prove what moved the needle.
