Worked on the usebruno/bruno repository to deliver a robust GraphQL introspection workflow, focusing on schema reliability and maintainability. Enhanced variable resolution by introducing folder-level support and improving header interpolation, while refactoring the GraphQL schema fetcher for clearer logic and expanded test coverage. Addressed utility function management by consolidating environment variable merging with lodash-based utilities and cleaning up legacy artifacts. Fixed several bugs, including issues with SVG render panels and duplicate variables, ensuring smoother front end and backend integration. Leveraged JavaScript, Node.js, and Jest throughout, emphasizing full stack development, code refactoring, and comprehensive software testing for business value.
