I led the UX/UI redesign of 1000Bulbs.com to improve usability, conversion, and mobile performance. Through user testing, stakeholder interviews, and analytics review, we identified key friction points and rebuilt navigation, product pages, and templates from the ground up. I directed the design system, collaborated cross-functionally with dev and marketing teams, and optimized layouts to align with brand identity and business goals. Early rollouts showed a 4.5% conversion rate and faster page load times (2.35s avg).
