I designed and developed the HERMES GUILD web app using Base44, building a community focused platform for readers to discover books and engage with curated literary content. I handled the full app structure including authentication flows, responsive UI, navigation architecture, and onboarding experience. My work focused on transforming the concept into a production ready MVP with stable user flows, scalable layout, and clean component structure. The platform demonstrates my expertise in Base44 app development, AI app migration readiness, and SaaS style user experience design.
