In March 2025, this developer created a Product Comparison Demo Page for the VisActor/VTable repository, focusing on data visualization and frontend development using JavaScript and Markdown. The demo page features a configurable row tree and conditional background coloring, allowing users to compare product specifications—such as robot vacuum models—while visually highlighting differences. By updating documentation and integrating these interactive elements, the developer enabled more effective sales demonstrations, onboarding, and feature validation for stakeholders. The work demonstrated a solid understanding of user-facing demo requirements and technical implementation, delivering a tangible tool that showcases VTable’s capabilities for both customers and internal teams.
