In one sentence

An offline profit calculator for Mercado Libre sellers.

The problem

Mercado Libre's fee structure — commission tier, shipping subsidy, tax withholding — makes real margin hard to see. Sellers price by feel and find out later.

Why I built it

Mexican marketplace sellers are underserved by tooling built for US platforms, and the calculation is local knowledge.

Who it is for

Mercado Libre sellers in Mexico pricing inventory.

Role

What I learned

Offline-first is the right default for a tool used standing in a warehouse. No network means no loading state, and no loading state means people actually use it.
