Lesy — A Full-Scale E-Commerce Marketplace | The Atom Studio

Lesy is the largest catalogue in this list by far — a genuine multi-category marketplace, not a single-brand storefront.

The Brief

Thousands of products across wildly different categories need a structure that doesn't collapse into a confusing mega-menu, and an order system that can handle the volume.

What We Built

• A product catalogue architecture built to scale across electronics, home, fashion, beauty, and groceries without losing coherence.
• An order system built for automated packing and fast delivery, not a manual, spreadsheet-driven process.
• Search and navigation designed for a catalogue this size, where a small site's category structure would fall apart.

Under the Hood

A Next.js THE ONE tier build — this is exactly the category of project that tier exists for: real infrastructure underneath, not a theme with more products loaded into it.

Lesy is live, a full-scale marketplace built the way marketplaces need to be built.
