I developed RESTful APIs to seamlessly connect the web application with backend services, significantly enhancing the user experience. I also took on DevOps responsibilities, ensuring smooth deployment and scalability of our applications. Using backend technologies like Django and Node.js, I built robust and scalable web applications, optimizing performance and maintaining high code quality. I implemented and maintained continuous integration and deployment processes to ensure efficient software delivery. Additionally, I conducted thorough testing and debugging to identify and resolve issues or bottlenecks in the backend system.
