Designing Fintastic required a dual focus: crafting complex system-wide pages and refining countless microinteractions. While the core functionality relied on handling large datasets and financial models, I had to ensure that even the smallest details—like transitions, hover states, and input feedback—were intuitive and responsive. Each interaction had to be seamless, enhancing user experience without adding friction. The challenge was balancing the large-scale structural design with the intricate, detailed behaviors users would encounter daily, ensuring that both worked together harmoniously.
