Summimarket

Buying and selling collectible cameras lacks a trusted middle layer. Summimarket is a curated auction platform that partners directly with sellers, reviews every piece, writes descriptions, and starts bidding at $1 so the market sets the price.

Designed the auction UX from first principles. Real-time bidding flows, lot detail pages, seller onboarding, and trust signals for high-value transactions. Every interaction reduces friction in a niche market where trust is paramount.

Rebuilt the bidding experience for mobile. 85% of bidders are on mobile, many joining for a single auction. Redesigned the end-to-end flow using progressive disclosure and modal patterns tuned for web constraints. Result: 60% faster completion for first-time bidders with measurably lower abandonment.

Full-stack ownership, design through deployment. React front-end, server infrastructure, payment processing, and auction timing logic. Responsible for brand, visual design, content strategy, and GTM positioning.
