At Mercado Livre, I build Go services for a business-critical visual workflow platform that powers customer-service resolution flows. I consolidated two contact-matching applications into one backward-compatible service, enabling the retirement of a backend application and related data resources.
I've also reduced a high-latency update flow through bulk processing, designed an MCP integration that reduced tool surface by 44%, and built event-driven integrations, asynchronous processing, and scheduled jobs. Previously, I delivered payment processing at Indutiva Tecnologia and high-traffic dock scheduling, freight tracking, and real-time monitoring systems at GMD Logística using .NET, Node.js, TypeScript, and Angular.
