As a full-stack developer, I extended a multi-tenant consultant portal SPA and assisted in the creation of a new B2C digital process portal. I implemented various GraphQL endpoints in a Java-based frontend aggregation layer, which I then consumed in the project's React and NextJS frontends. A significant part of my contributions was the creation of a GraphQL proxy service capable of analyzing, modifying, and forwarding GraphQL queries to another service. In addition, I provided guidance on front-end and back-end development best practices and assisted in the setup of new services.
