The star rating is calculated by averaging the reviews provided by all clients the talent has worked with for a significant amount of time.

If such data is not available, the star rating is calculated from the fraction of work sessions approved by their past clients versus the total tracked by the talent.

If such data is not available, the star rating defaults to the interview rating of the talent at the time of the vetting process.

Other data including reviews from interviews are available on the talents’ profiles but do not influence their star rating, though they do influence their position in the search results.

Bootstrap
CSS
React

I created a frontend facing React Single Page App for an existing RickandMorty API. I created reusable cards in React to display the content fetched from the API.
I used Bootstrap which minimised the amount of CSS I had to write by providing helper classes for styling the rendered cards.
I also used the CSS grid feature to ensure that the displayed cards were mobile responsive without the need of adding media tags.

I used CSS to style the threaded comment section of an article to visually indicate the history of the comment.
I used Postman to test out the functionality of the API, testing HTTP success and error responses as well as testing for edge and corner cases expected from the frontend integration.
