For ChartUp, a crypto startup, I designed and developed a custom calculator that seamlessly integrates live price data with interactive user inputs. The calculator pulls real-time cryptocurrency prices via an API and allows users to adjust four sliders to explore various scenarios and calculate dynamic totals. This project showcases my ability to create engaging, data-driven user experiences entirely within Framer, enhanced by custom coding for advanced functionality.
The most challenging aspect of this project was ensuring the calculator handled live data efficiently while maintaining smooth user interactions. The sliders required bespoke coding to allow precise adjustments and a fluid, responsive interface, all while synchronising with API updates in real time. From managing asynchronous data flows to optimising the visual design for clarity and ease of use, I focused on crafting a tool that feels intuitive while delivering highly accurate calculations.
This project reflects my expertise in combining Framer’s native capabilities with custom code to deliver powerful, interactive features. Whether it's pulling live data, integrating bespoke UI elements, or ensuring cross-platform responsiveness, the ChartUp calculator is a testament to my ability to turn complex technical challenges into sleek, user-friendly solutions.
