Hi, I'm Denis Duran i Báñez, a Barcelona-based Full Stack Developer with a passion for building robust, scalable web applications and SaaS platforms. I specialize in modern front-end and back-end stacks, including Next.js, React, FastAPI, and SQL-based persistence, and I enjoy creating secure, multi-tenant solutions that scale across clients. I value code quality, continuous learning, and delivering real value to teams and products. I have contributed to multi-tenant architectures, authentication integrations with Keycloak, and REST API development, always focusing on a great user experience and robust software design.…Hi, I'm Denis Duran i Báñez, a Barcelona-based Full Stack Developer with a passion for building robust, scalable web applications and SaaS platforms.
