At Luizalabs (Magalu), I help keep the App and Web platform resilient during high-traffic events like Black Friday. I also led the end-to-end redesign of product search across App, Desktop, and Mobile Web, optimizing query performance and product discovery.
Across TOTVS, Serasa, and Senior Sistemas, I worked on mobile architecture migration, real-time payment validators, low-latency authentication, and Go microservices. At Serasa, I developed batch jobs that synchronized more than 2 million user records.
