At Jumbo, I built EV-based casino games from 0 to 1, including a 25-tile Mines title with 3/5/7-mine modes. I owned payout tables, house-edge parameters, volatility curves, and post-launch tuning; the game reached $19M in annualised wagered volume at a 2% realised house edge.

I also built the operator back office, covering payment-gateway traffic control, market and contest lifecycles, risk checks, and support tooling. I designed a payment orchestration layer processing $313K per day and an idempotent ledger with automated reconciliation that prevented $73K in losses.

At Jumbo, I scaled an opinion-trading product from 0 to $105K per day in GMV, with peaks of $420K per day on IPL matchdays. I owned its monetisation model, which delivered a 5% blended take rate and a 45% revenue uplift, and led a 17-person cross-functional pod reporting to the CTO and co-founders.

Before Jumbo, I was a Strategy Associate at Probo. I designed hyperlocal sports tournaments that generated ₹10 Cr in annual revenue from markets built on their fixtures, converted 1,600+ leads into 130+ corporate partnerships, and scaled live-streamed sports events to 800,000+ organic views and 15,000+ subscribers. I'm now moving to the supply side of iGaming.
