Top SchoolGuilherme Vieira is a Principal Software Engineer with over two decades of software experience and more than a decade in senior engineering roles, currently building scalable, secure multi-tenant infrastructure for AI agent platforms at CrewAI.

Previously a founder whose sales-rep operations company was acquired, he has driven platform and performance improvements at Toptal and Clearbit, often turning ambiguous problems into production systems that scale. Based in Rio Grande do Sul, Brazil, he pairs a Computer Science background and an MBA with a practical obsession for developer experience and operational patterns that make AI agents useful in real businesses. An unusual strength is his end-to-end fluency from code to executive partnerships, enabling him to reduce costs dramatically (up to 90% compute reductions) while accelerating secure, observable deployments.
