Rovshan Musayev presented on building a serverless self-service framework using AWS Lambda. He discussed how the need for automation led to creating a self-service model where teams can provision resources without asking. The framework uses AWS services like API Gateway, Lambda, SQS, and DynamoDB along with CI/CD tools. Testing is done through mocking and unit testing. Lessons learned include the importance of testing from the start and avoiding long living branches in source control.
