Cover image for User journey for the FGV
User journey for the FGV Undergraduate website I led user journey mapping for the FGV Undergraduate website to improve conversion, engagement and clarity across the candidate experience. Analyzing the journey from awareness to post-registration, I identified friction points such as fragmented information and mobile usability issues. This informed UX and content hypotheses focused on centralizing admission details, standardizing course pages, highlighting key data like enrollment methods and deadlines, and strengthening storytelling through course differentiators and student experiences. These improvements reduced cognitive load, increased confidence, and guided candidates toward enrollment, contributing to higher engagement, smoother decisions, and a more conversion-driven experience aligned with FGV’s strategic goals.

Cover image for New FGV Undergraduate Website As Product Designer
New FGV Undergraduate Website As Product Designer on the FGV Undergraduate Website project, I led the end-to-end design process to unify a fragmented digital ecosystem into a cohesive, user-centered platform. I mapped the full candidate journey, defined information architecture and structured the site based on real user needs and decision stages, from discovery to delivery, ensuring that key content and actions were easy to find. I translated research into navigable wireframes, conducted usability tests to validate assumptions and incorporated insights into the final UI, all while aligning the visual design with FGV’s design system to create a more intuitive, engaging and high-conversion experience.

Organic Performance Report I led the conception and execution of the organic performance report for the FGV Undergraduate website to understand how SEO, user behavior and conversion impacted overall results. I integrated data from Google Analytics and Google Search Console to analyze traffic, sessions, clicks, impressions and rankings. I also used ChatGPT to support competitive SERP analysis and track sessions originating from ChatGPT, expanding insights into emerging discovery channels. To deepen user experience analysis, I reviewed behavioral data and satisfaction surveys through Hotjar. The synthesis of these sources generated actionable insights that fed a continuous UX / CRO optimization backlog, guiding testing initiatives, content improvements and conversion flows within an ongoing monitoring framework focused on growth.
