I developed a severless web app for users to create a page to consolidate all of the links they want to share with other people (Facebook, Twitter, Instagram, GitHub, etc) in one place. I solely did all of the work on it including design, back-end work, front-end work, and development automation. It was primarily built with the Python Flask framework and runs on AWS Lambda with DynamoDB as a database. The vast majority of the codebase was covered by unit and integration tests which were automatically run on every pull request. Every component, including a duplicate development copy, was hosted within AWS. Billing was handled by Stripe.
The old website was https://lksg.me/.
