I have experience with GraphQL APIs and Apollo Client, which offer significant advantages over REST APIs. With GraphQL, we can determine the response type on the client side, reducing response size and latency, thereby improving performance.

In my personal projects, I have implemented GraphQL. For instance, in a live sports score application, I used GraphQL for real-time updates, efficiently handling complex data queries.

I integrated Apollo Client to manage GraphQL queries and mutations, which simplified the process of fetching and updating data. With Apollo Client, I achieved real-time data synchronization.

Although I have not used these technologies in company projects, I have gained valuable experience with GraphQL and Apollo Client and am ready to apply this knowledge in professional settings.
