I have several mini projects in motion and a growing to-do list across a Spring Boot back-end and Angular / React front-ends. The most urgent item is fleshing out clean, well-documented REST APIs in Spring Boot that feed the existing UI layers. Typical tasks include defining entities, repositories and service classes, wiring controllers, mapping DTOs, validating input, and writing unit tests. As soon as an endpoint is stable, it needs to be consumed by either the Angular or React interface with a responsive, polished user experience. The codebase lives in Git; each feature is tracked in small Jira tickets so the scope stays tight. After completing a ticket, simply open a pull request, add Swagger or Postman collections for quick testing, and walk me through the changes on a short call. GraphQL, Kafka, and AWS sit on the roadmap for later phases, so prior exposure to those tools will definitely help when we begin integrating messaging and cloud deployment. Deliverables per ticket • Spring Boot REST endpoint(s) fully functional and tested • Updated Angular or React components hooked to those endpoints • Swagger / Postman documentation for the new API surface • JUnit / Mockito back-end tests and front-end test coverage where applicable • Brief hand-off notes explaining design decisions Acceptance criteria: Maven build passes, all tests are green, the UI compiles without warnings, and each endpoint returns the expected payload as specified in the ticket. Work kicks off immediately, with milestones scoped small so progress is visible and feedback is fast.

Hi there, I can work ticket-by-ticket within your existing Git/Jira workflow, building clean Spring Boot APIs and connecting them properly with your Angular/React interfaces. I’m comfortable working with small, well-defined tickets and keeping each change tested, documented and production-ready before moving to the next one. I also have experience with PostgreSQL/MySQL, Docker and cloud environments, with exposure to GraphQL, Kafka and AWS for future phases. ❓Can you share the existing Git/Jira setup and the first ticket you’d like me to start with? ❓Is the current Angular/React UI already structured around reusable components/services? ♾️ That's all for now. I can commence immediately. I am open to a chat to proceed forward with the next step. Thank You.

You need Spring Boot REST APIs built out, and the Angular and React screens wired to them. I have 8+ years of experience in web development and have delivered hundreds of projects using Spring Boot, Angular and React. I take one ticket at a time: entity, repository, service, controller, DTO mapping, validation, then JUnit and Mockito tests. When the endpoint passes I hook it into the Angular or React component and check the payload. I am fully confident I can deliver this for you, and I will give my 100% until it works exactly the way you want. Unlimited revisions until you are satisfied. I can start right away.

Hi Shahid, Thank you for posting this good task! I like the ticket by ticket structure with Jira, PRs and a quick call per feature, that keeps scope tight and reviewable, which is exactly how I prefer to work on an ongoing codebase rather than getting handed a vague backlog. I have solid hands on experience with Java and Spring Boot, building entities, repositories, service layers and controllers with proper DTO mapping and input validation, along with JUnit and Mockito for backend tests. On the frontend side I work comfortably in both Angular and React, and on a project called Annexa I designed and shipped over fifty REST style backend endpoints consumed by a Vue frontend with role based access, so the pattern of stabilizing an endpoint then wiring it cleanly into a responsive UI is very familiar. I've also used NestJS with GraphQL and Prisma on other work, so the roadmap items you mentioned for later phases won't be new territory when you get there. For each ticket I'd deliver the Spring Boot endpoint with tests green, the matching Angular or React component wired in and responsive, Swagger or Postman docs, and a short note on the design decisions before we hop on a call. Happy to start immediately at my hourly rate of 25 USD. Best regards, Diah

Hi there, I see you're looking to flesh out REST APIs in Spring Boot for existing Angular and React interfaces. I can ensure the endpoints are well-documented and stable by utilizing JUnit for thorough testing alongside Swagger or Postman for easy interface validation. In addition, I'll make sure to keep the front-end components responsive and polished while connecting them to the back-end services. It's great that you're utilizing Git and Jira for task tracking as it allows for streamlined pull requests. I'll compile hand-off notes after completing each task to clarify design decisions and ensure smooth progress. If you're open to it, I would like to confirm whether you have any preferred methods for unit testing and documentation that you currently use. Happy to discuss the details to suggest the best technical approach. Regards, Ali

Hi. I can work through your Spring Boot + Angular/React tickets one by one and keep each change small, tested, and easy to review. I am very familiar with Java, Spring Boot, REST APIs, JPA/Hibernate, DTO mapping, validation, Angular, React, PostgreSQL/MySQL, Git, Jira, Swagger/OpenAPI, Postman, JUnit, and Mockito. For each ticket, I would first understand the expected request/response contract, then implement the entity/repository/service/controller layers, add validation and tests, connect the endpoint to the existing UI, and open a clean PR with documentation. I focus on avoiding unnecessary refactoring and keeping existing projects stable while adding new functionality. I am also comfortable with GraphQL, Kafka, AWS, CI/CD, and can support those later as the project expands. I can start immediately and work directly through your Git/Jira workflow. Thanks for your attention.

Hello, I’d like to suggest starting by standardizing the Spring Boot API layer, DTO contracts, validation, centralized exception handling, consistent responses, and Swagger/OpenAPI. This will make Angular/React integration smoother now and help avoid rework when GraphQL, Kafka, and AWS come into the roadmap. I can handle each Jira ticket end-to-end, from entities, repositories, services, and controllers to JUnit/Mockito tests and front-end integration. I’ll keep PRs small and reviewable, provide clear hand-off notes, and ensure Maven builds, tests, UI compilation, and API payloads meet your acceptance criteria. Ready to jump in immediately and deliver feature-by-feature with fast feedback. Best, Niral

Hi, I’m very interested in this project because the small-ticket, test-driven workflow allows each feature to move cleanly from API design through UI integration and review. For each Jira ticket, I can handle the complete implementation: - Spring Boot entities, repositories, services, and controllers - DTO mapping that keeps persistence models out of API contracts - Bean Validation, consistent errors, and exception handling - Transaction boundaries, pagination, filtering, and authorization - Angular or React integration with responsive loading, empty, success, and error states - OpenAPI/Swagger updates and importable Postman collections - JUnit and Mockito tests, plus relevant frontend coverage Before coding, I’ll confirm the payload contract, status codes, validation rules, permissions, and edge cases. I’ll keep PRs focused, use clear commits, and include setup notes, migration details, test evidence, and the reasoning behind important design decisions. My completion gate will match yours: successful Maven build, green automated tests, clean frontend compilation, verified API responses, and an end-to-end check through the UI. I’m also comfortable working within Git/Jira workflows and can contribute when the roadmap expands into GraphQL, Kafka, and AWS. I’m available to start immediately. Please share the first ticket, repository setup, and current Spring Boot/Java versions. Best

Hi there, Building robust Spring Boot REST APIs and seamlessly connecting them to React or Angular UIs requires tight synchronization to keep your Jira backlog moving without bottlenecks. A common pitfall in multi-stack mini-projects is inconsistent DTO mapping and lagging test coverage that breaks the Maven build upon integration. My solution is to deliver fully tested endpoints with clean architecture, complete Swagger documentation, and responsive UI components per ticket, ensuring every pull request is green from day one. To help me tailor the initial setup, here are my questions: 1. Are you currently using a specific database like MongoDB for these initial Spring Boot entities, or is it relational? 2. Do you prefer the first few tickets to focus primarily on Angular or React front-ends? Drop me a message so we can get started right away.
