This case study shows how I designed a landing page for a complex HealthTech weight loss program with almost no initial materials. I approached it as a full UX and product challenge: researching, defining structure, drafting content, and designing all user flows and interactions. The goal was to turn a complicated medical process into a clear, trustworthy, and conversion-focused experience. AI tools were used for both research and generating custom visual assets, saving significant time and budget. This project demonstrates a proactive, product-oriented approach to design, focused on real user and business outcomes.
