Snapp! Express

I led the transition from a restrictive vendor-first model to a unified "Product-Based" experience by analyzing quantitative funnels (Metabase) and qualitative behaviors (Hotjar session recordings and usability tests).

To reduce interaction cost, I completely redesigned the core purchase flow. This iterative, data-driven strategy drastically shortened the user journey and decision time.

  • Successfully shifted user behavior by prioritizing product discovery over store selection;

  • Scaled the feature from an experimental MVP to a core flow, increasing search-to-cart conversion;

  • Established a robust foundation for a vendor-less shopping architecture across the platform.

Hamrahtel

I led as Product Design Lead with a dual mandate: build the team and modernize the product without disrupting a live operation. I assembled the product design team end-to-end defining roles, hiring and onboarding, and setting rituals (crits, design reviews, async specs) that tightened our collaboration with Product & Engineering.

In parallel, I architected a new design system (tokens, components, accessibility, content guidelines) with clear governance and versioning, enabling consistent, scalable UI across surfaces.

To de-risk change, I audited and documented every current-state flow, clarified ownership, and established canonical user journeys. I then planned and managed a phased migration to the new system rollouts, compatibility tracking, and team training so we could evolve the experience step by step while maintaining service continuity.
