At Mercado Livre, I own the service behind the full lifecycle of electronic freight invoices in Brazil, from generation and tax-authority authorization to cancellation and storage. It handles millions of documents per day, and I redesigned its contingency flow so documents keep being issued when the tax authority is unavailable.
I also built Mercado Livre’s Mexico e-invoicing integration, which issues around a million invoices per day, and created the public fiscal gateway used by carrier integrators and sellers. I take initiatives from discovery and cross-team alignment through architecture proposals and delivery.
I designed a multi-agent pipeline using Claude and MCP servers to take Jira tasks from analysis through implementation, validation, reviews and deployment; it roughly doubled my sprint throughput. Before Mercado Livre, I built Go backends for an Electronic Health Record and telemedicine platform, and built and led Megys B2C, an e-commerce platform serving around 15 online stores.
