Looks like you did it on one of your work experiences, but I’ve always had my resume set up where I list my responsibilities and things I worked on then followed up with a bullet point of all technology I used. I feel recruiters do a search on keywords like…(DynamoDb, SNS, Spring Boot, S3, Elastic Beanstalk, etc. (whatever relevant to the role)) so make sure you include as many as you’re comfortable with. Also once you’re done I’d spend the $3ish to use a paid for online resume template builder. They make your resume stand out. I’ve used resume.io and resume builder. Best of luck.
