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 showcased a product comparison table for robot vacuum models, featuring configurable row trees and conditional background coloring to highlight differences between products. This user-facing demo was designed to support sales presentations, onboarding, and feature validation by making VTable’s capabilities tangible for stakeholders. The developer also updated documentation to guide users in leveraging the new demo. The work demonstrated depth in frontend engineering and thoughtful integration of interactive visualization techniques.
