I’m rolling out a new feature that touches both ends of our stack. On the backend we run Java 21 with Spring Boot micro-services, alongside a small Node.js/Python layer that exchanges events through Kafka. The frontend is split between an older Angular module and a newer React interface. The job is to design and code the complete feature, wiring it cleanly into every affected service and UI surface. You will: • Extend (or create) the relevant Spring Boot endpoints, making sure they publish and consume the right Kafka topics. • Update the Angular dashboard and the React SPA so the user experience is seamless across both frameworks. • Keep code idiomatic, unit-tested, and pushed to our Git repo via pull requests. Acceptance criteria • All API tests pass in CI and new tests cover at least the happy path plus one failure mode. • Kafka messages appear in the correct topic with the defined schema. • Angular and React components render the new data without console errors and match the provided Figma spec. • A short README explains setup and any new environment variables. I’m available on Slack for quick clarifications and can review progress daily. If you’ve shipped similar cross-stack features before—especially where Spring Boot, Angular, React and Kafka meet—let’s get started.
