Backend for a user to manage settings

I need a user settings page for my project to manage settings in DynamoDB. The whole project should be deployed on AWS. Layout can be used from this project https://github.com/altence/lightence-ant-design-react-template .
One page should display list of repositories and their parameters. Every item on the list can be edited by user (when 'Edit' button is clicked)
Data model is simple :
- Repository
-- name
-- url
-- branch
-- public key
Second page 'Settings' should contain simple user settings :
- name
- avatar
- password
