Hello, I can help you fix and extend your Java REST backend. I am comfortable with Java 17, Maven, and Spring Boot or JAX-RS style REST architectures. I can diagnose and fix the existing GET and POST issues in your current service layer and model structure. I will also add new clean, well-documented endpoints that follow your existing JSON schema and HTTP standards. Each fix will include proper status codes, error handling, and stability improvements. I can also add unit or integration tests to confirm every fix works end-to-end before merging. I prefer task-based tracking so each issue is clearly resolved and verifiable for payment. For the first set of bugs, I can start immediately and typically deliver initial fixes within 24 to 48 hours depending on complexity. Ready to review your repository and begin right away.

I understand your Java REST API has breaking issues in existing endpoints and needs reliable fixes along with new GET and POST endpoints. I will first analyse the current REST layer, services, and models to identify root causes, then resolve bugs ensuring correct JSON responses and HTTP status handling. I will add clean, well structured endpoints following Spring Boot or JAX RS standards. Each fix will include unit or integration tests to validate end to end functionality. I prefer task based work for clear tracking per fix. I can start immediately and deliver quick, stable resolutions with properly tested and merge ready code.

@gloifytech

Hi, The requirement is clear and well defined. Fixing REST issues while keeping responses consistent and reliable is something I work on regularly. I can start by tracing the root cause across the REST layer, services, and model classes to resolve the current GET and POST failures. Along with fixes, I will add new endpoints that strictly follow your existing JSON schema and return correct HTTP status codes. The code will remain clean, structured, and aligned with Java 17 and Maven practices. I will also include focused unit or integration tests to validate each fix and endpoint end to end, ensuring smooth verification and no regression. Comfortable working with Spring Boot and JAX RS patterns, so adapting to your setup will be quick. Each update will be delivered via clear pull requests that build without warnings and pass all tests. Task based tracking works well for this model. I can begin immediately and deliver the first set of fixes with a fast turnaround. Looking forward to collaborating.

Legacy issues causing failures in your current GET and POST calls demand immediate attention, especially within the Java REST API framework you’re using. As part of my approach, I’ll thoroughly diagnose the REST layer, ensuring existing bugs are swiftly resolved while adhering to your current JSON schema and HTTP status code requirements. I’ll also develop clean and well-documented endpoints, complemented by concise unit tests, all within 5 days for the initial deliverables. Do you have a specific timeline for the first milestone?

@Taha2423

I focus on delivering clean, reliable, and practical solutions that solve the real problem, not just writing code. I have experience working across different technologies and adapting quickly to project requirements. My priority is to build something that is efficient, maintainable, and easy for you to use later. I communicate clearly, give regular updates, and make sure the work stays aligned with your goals. I also care about quality, deadlines, and long-term value, so you get more than just a quick fix. I would be happy to discuss your project in detail and suggest the best approach before starting. Looking forward to the opportunity to help you complete this successfully.

Hi, Yes, I can work on this. I’m comfortable with Java 17, REST APIs, and debugging Spring Boot/JAX-RS based systems. I can help: * Diagnose and fix existing REST API issues (GET/POST) * Add new endpoints with proper JSON responses and status codes * Ensure clean, maintainable code with tests for each fix I’m fine with **task-based payment (₹1,200 per issue)** — that works well for quick delivery. For the first set of bugs, I can start immediately and provide fixes within **1–2 days**, depending on complexity. Please share the repository access and the list of current issues so I can begin. Thanks.

Hello, I’d be happy to help with your Java backend REST fixes and endpoint additions. I have experience with **Java 17**, **Spring Boot/JAX-RS**, **Maven**, REST API debugging, and building reliable, test-covered backend services. I can diagnose legacy issues across controllers, services, and model layers, fix broken GET/POST flows, add new endpoints aligned with your JSON schema and correct HTTP status handling, and provide concise unit/integration tests for each change. I prefer **task-based billing** at your per-bug structure (₹1,200 per confirmed fix), as it aligns well with clearly scoped issues, though I’m also open to hourly if ongoing investigation is needed. For the **first set of bugs**, I can begin immediately and expect an initial turnaround of **1–2 days**, depending on issue complexity. My deliverables will include: * Clean, maintainable fixes with PR-ready code * Well-documented endpoints * Green automated tests and manual verification support * Build passing without warnings * Clear communication on root cause and resolution for each issue I’m ready to start quickly and can review the first bug list as soon as you share access/details.
