Rockstar🎓
Top SchoolMateus Félix is a frontend-focused software engineer with nine years of experience building polished, user-centered interfaces and testable code from São Paulo. Known as a "Professional Pixel Painter," he pairs a designer's attention to detail with deep curiosity about software architecture, Node.js, NestJS, TypeScript, Docker and MongoDB. He contributes to open-source tooling for robust front-end testing—improving the popular Testing Library ESLint plugin's no-container rule—to help teams catch anti-patterns earlier. Trained in full-stack web development at Ironhack, he brings practical end-to-end perspective and a habit of exploring atypical architectural patterns to make front-end systems more maintainable and testable.
