Back to original languageAbout Nicolas
Software development engineer with solid expertise in React, Node.js, and React Native, I design robust, high-performance, and user-friendly web and mobile applications. Thanks to my freelance experiences in various environments (health, cloud, insurance, logistics), I master the entire agile project lifecycle, from functional scoping to continuous deployment. My full-stack skills also extend to cloud technologies (AWS, Azure, GCP), CI/CD integration, and UI/UX optimization. Curious, rigorous, and adaptable, I am always motivated by innovative projects with high added value.
