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.

✋ Hello! We are dZENcode, a software development company.
We can build this cross-stack feature for you and wire it cleanly into the existing services and UI.
1. Do you already have the Figma spec and expected Kafka topic schema?
2. Should we start from the existing Angular module, React SPA, or both at once?
For reference (company overview ):

207 1 day100 USDHi John! This is exactly the kind of cross-stack work I’ve been doing recently.
I’m a Java backend developer with solid experience in Java 21 + Spring Boot, building APIs, handling async flows, and integrating external services. In my recent project, I worked with real-time communication (WebSockets, event-driven flows), AWS services, and designed backend logic that coordinates multiple components—similar to your Kafka-based interaction model.
On the frontend side, I’ve worked with Angular and have a good understanding of integrating backend APIs into UI flows. While React isn’t my primary framework, I’m comfortable navigating and extending existing codebases to deliver consistent features across both UIs.
I focus on clean, maintainable code, proper error handling, and making sure everything is testable and production-ready. I’m also used to CI/CD workflows, Docker, and collaborative development via PRs.
Happy to jump in, clarify requirements quickly, and deliver this feature end-to-end.

My name is Jeo Vincent Carretas, and I am interested in your project. I have experience working with full-stack systems, including Spring Boot, APIs, and modern frontend frameworks like React and Angular. I can implement the feature across backend and frontend, ensure clean Kafka integration, and deliver well-tested, stable code.
I am ready to start and collaborate closely with your team.
Thank you for your time.
Best regards,
… Jeo Vincent Carretas

I’ve worked on cross-stack features involving Java (Spring Boot), Kafka, and mixed frontends (Angular + React), so this setup is familiar.
I can handle the full cycle:
— extend/create Spring Boot endpoints with proper Kafka integration
— connect Node/Python event layer if needed
— update both Angular and React UI for a consistent UX
— write clean, tested code and deliver via PRs
… I focus on stability, clear architecture, and meeting CI/testing requirements (API tests, Kafka schema, UI without errors).
Can start immediately. Happy to review Figma and align on details.

240 5 days250 USDI have experience working with similar architecture: Spring Boot (microservices), integration through Kafka, as well as supporting a hybrid frontend (Angular + React). I understand the importance of consistency between services, correct event handling, and clean integration at the UI level.
From my side, I can:
• Design and implement endpoints in Spring Boot with proper publishing/consuming of Kafka topics
• Ensure stable interaction between services (including Node.js/Python layer if needed)
• Carefully integrate changes in Angular and React to maintain consistent UX
• Cover functionality with tests (happy path + edge cases) and prepare everything for CI
• Create a README with explanations for setup and environment variables
… I work through Git with pull requests, adhering to clean and maintainable code.
