About the creator

Benoit Boure

With several years of experience building GraphQL APIs using AWS AppSync, I have consistently faced challenges when it comes to testing and debugging. To address this pain point, I developed GraphBolt, an all-in-one solution that streamlines the process of working with AWS AppSync, making it easier to understand what is happening inside resolvers and how they interact with the data sources.
