  Allocated to Luizalabs , the technology sector of MagazineLuiza marketplace, by PISOMTECH (indirect contract). As a holding retail company, Magazine Luiza has acquired a large set of e-commerces and marketplaces.

Developed a payment split API to replace an existing, and expensive, 3rd party paid software. Trained other developers helping them to grow both technically and personally. Currently working on an internal API collection migration from a legacy APIs product to another new ones. This migration involves multiple stacks using Java, Node, Python and React.
