Senior🎓
Top SchoolJoão Guilherme is a software engineer with 11 years of experience focused on frontend systems, analytics-driven product improvements, and delivering complex in-browser data experiences. He has led front-end architecture and built high-performance browser-side platforms—authoring a visual orchestration flow editor and an AI-powered code editor—while maintaining cohesive design systems and sub-second performance under heavy data loads. Skilled in React, Vue, TypeScript and analytics tooling (Mixpanel, PostHog), he pairs hands-on implementation with data-informed decision making. His background spans startups and public-sector projects, from building Android apps and dashboards to improving open-source government systems with Docker and CI practices. Now at Nubank’s Data Business Unit, he continues to blend user-focused engineering with measurable outcomes, and he’s an avid hiker who treats developer ergonomics like trail planning: anticipate, simplify, iterate.
