I will develop a product comparison widget

I take on product comparison widgets and conduct the project from idea to a finished module in your store. The buyer marks several cards in the catalog with checkboxes, and nearby opens a table where all parameters of the selected products stand line by line — weight, size, material, warranty, any attributes that really influence the choice in your niche. Before layout, I analyze the catalog structure and decide which fields to display in the comparison and which only clutter the table: the point of the tool is to show the difference, not dump the entire list of properties from the database.

I open the widget as a popup panel or a separate page — I look at the catalog structure and convenience for the visitor. Rows where values differ I highlight in color so the buyer can read the difference in a second rather than re-read the table twice. I do the whole cycle myself: layout for your current theme, comparison logic and a simple admin panel through which the team can enable and disable attributes without a programmer. On a phone the table doesn't break but transforms into cards for scrolling.

I've built such widgets for electronics, furniture and construction materials stores, each time adapting the presentation to the category. Along with the widget I provide:

— clean code with comments for further development
— color highlighting of differences with admin panel settings
— responsive layout for phones and tablets
— testing on real catalog categories before project delivery
