Learning budget

I'm a full-stack web dev with 3 YOE trying to migrate into devops. So, I'm collaborating with a friend who is building a mobile app with node server, SQL db and I'm responsible for the infrastructure. I'd like to try stuff like github actions, docker, managed db service, storage, load balancer, testing environment and so on. My first instinct was to pick AWS as our cloud service because it's the most popular and probably looks best on resume
