What I'm looking for

I’m looking to design end-to-end customer journeys and dashboards, collaborating with engineering to deliver complex UX logic, using prototyping, usability testing, A/B testing, and scalable design systems to drive product results.

I’m a senior UX/UI and product designer focused on improving customer journeys end-to-end—onboarding, progress tracking, training program planning, and exercise tracking for mobile products.

Across my roles, I generate hypotheses, prototype, run usability testing, conduct A/B testing and surveys, and turn results into measurable UX changes (e.g., simplifying dashboards to increase conversion by 5%).

I also build scalable UX patterns, maintain design systems, create branding guidelines and promotional materials, and work closely with engineering leads to ensure smooth delivery of complex UX logic across multiple product teams.
