Search & Discovery

Built ESPN BET's search experience from zero — cutting zero-result queries by 35%, nearly doubling search's share of total handle, and growing bet conversion through two years of iteration and a ground-up redesign.

Parlay Lounge - a Pre-built Parlay Experience

Identified a competitive gap, pitched the concept internally, and built Parlay Lounge from scratch — a curated pre-built parlay experience that became one of the most-used features on ESPN BET and theScore BET, driving meaningful parlay handle and an extraordinary add-to-bet conversion rate.

Spotlight Carousel

Conceived and built Spotlight Carousel from scratch — a CMS-driven, full-width homepage feature that surfaces curated betting events with a direct bet-to-betslip flow. During March Madness 2026, Spotlight was the origin point for 50%+ of all bets placed on featured games. Now live across eight sports.
