Completed a Docker course on LinkedIn Learning focused on containerization and modern application deployment.
The course covered core Docker concepts including containers, images, Dockerfiles, volumes, and networking. I also learned how to containerize applications, manage environments efficiently, and deploy scalable applications using Docker.
This certification strengthened my understanding of DevOps practices and improved my ability to build and deploy backend and full-stack applications in consistent and portable environments.
