Education
Full Stack Open is a free university-level course from the University of Helsinki that teaches modern full-stack development. It covers React, Redux, Node.js, Express, MongoDB, GraphQL, TypeScript, React Native, CI/CD, and containers. The course is entirely project-based with no hand-holding — you build real apps from scratch. It is widely regarded as one of the best free resources for developers who already know the basics and want to level up to production-quality full-stack skills.
