Built the full data-driven front-end layer for a crypto ETF (GSR Crypto Core3) marketing website in Webflow, integrating custom JavaScript with a live financial data API. The solution features dynamic performance charts (Chart.js), a holdings table, and quarterly premium/discount statistics pulled from real-time data, complete with CSV export functionality. The project involved close collaboration with the backend developer and compliance team, from troubleshooting API integration issues to meeting regulatory display requirements (SEC-compliant formatting).
