I basically don't manage any servers. Everything runs on AWS Lambda & co (DynamoDB, S3,...) It doesn't prevent an app-level outage (corrupted data in the database, bad architecture,...) but at least I don't have to worry about servers going down anymore. As for the rest, unit & extensive integration tests along with continuous integration and linting. Oh, and a typed language. Moving from Javascript to Typescript was a blessing. But I still miss Swift.
