Java REST API Bug Fixes

@OutsourceMan

As a seasoned professional with more than 18 years of experience under my belt, I bring a wealth of knowledge and expertise to the world of API Development. I am comfortable working with a wide array of technologies, including Java, Git, Maven, and REST frameworks, which makes me an excellent fit for this project. I have spent considerable time specializing in MySQL, which will be invaluable when it comes to diagnosing and resolving any issues you may be experiencing. One factor that sets me apart from my counterparts is my commitment to quality. I seek not just to resolve the current issues at hand but also to enhance and fortify your existing codebase in order to minimize any potential risks. Rest assured, your REST layer and related model classes will receive the care they deserve. Another aspect worth mentioning is our attention to detail when it comes to documentation and testing. Each fix or new endpoint added will come with concise unit or integration tests that demonstrate their functionality end-to-end. This meticulous approach guarantees high-quality deliverables that align perfectly with your specified acceptance criteria.

As an experienced software developer, I assert that I can provide the vital support your project requires. Throughout my nine years in the field, I have both independently and collaboratively handled challenges similar to the ones you've outlined for this Java REST API project. To begin with, my Java skills have consistently proven to be reliable as demonstrated by my ability to fix legacy issues and add new endpoints while ensuring clean, well-documented GET and POST operations. A critical aspect of my work is a long-term concern for architecting scalable and maintainable systems. This approach enhances project reliability by minimizing potential bugs upfront rather than fixing them when their impact has magnified. My proficiency in Hibernate/JPA, Spring Boot, and AWS-based deployments will be particularly useful in ensuring that your system remains well-designed, high-performing, and easily maintainable even after the delivery stages. To add icing to the cake, I am also highly competent at incorporating artificial intelligence into backend processes as well as using AI tools for code quality improvement. By leveraging REST-based AI/LLM APIs such as GPT and Codex in previous projects, I assure you of a pragmatic yet intelligent approach to achieving prompt and efficient results that adhere to the stipulated JSON schema standards. Hiring me ensures your project is handled with professional finesse while delivering on time at competitive rates.

I'm so glad to come across your project! My name is Nitin and I represent SoftwareLinkers, a team trusted by numerous industries including education, finance, startup, and more for delivering top-notch software development solutions for over years. API Development has been one of our fortes for a long time and we're quite adept at handling Java RESTful APIs as you've described in the job. Working with Java 17, Git, Maven is something we're familiar with and comfortable using on a regular basis. Since the use of typical Spring Boot and JAX-RS patterns are right up our alley, we could seamlessly blend in with your development setup and contribute effectively from the get-go. The fact that we not only listen but also understand our clients' needs puts me in a great position to assure you that we would prioritize flawless REST layer functioning alongside crafting clean GET and POST endpoints. Importantly, given our proficiency at documenting the process meticulously – including API responses based on your JSON schema – your integration process with our deliverables will be hiccup-free.

@SmartCodeDev

Hello, I can quickly diagnose and fix your REST API issues and add clean, reliable endpoints in your Java backend. I’m comfortable with Java 17, Maven, and REST frameworks like Spring Boot and JAX RS. I will resolve GET and POST errors, ensure correct JSON responses, and proper HTTP status handling. New endpoints will be clean, well structured, and fully documented. I will include unit or integration tests to validate each fix end to end. Code will be clean, build without warnings, and ready for smooth PR review. I prefer task based billing per fix for clarity and faster delivery. First set of bugs can be resolved within 1 to 2 days depending on complexity. Ready to start immediately.

Hi With 8+ years of experience in java spring boot and microservices, I am very exited to work on this project. It would be good if we can discuss further about it. I will charge per bug fix. Best

@ThinhSenDev

Hi, I can help you quickly stabilize and extend your Java REST backend. I have 8+ years working with Java (Spring Boot, REST APIs, Maven) and have handled similar cases involving legacy bugs and endpoint inconsistencies. What I’ll deliver: Fix existing GET/POST issues at root cause (REST layer, service, or model) Add clean, well-structured endpoints following your current JSON schema Ensure correct HTTP status handling and consistent responses Provide concise unit/integration tests to validate each fix end-to-end Clean, readable code aligned with standard patterns (Spring/JAX-RS) How I work: Fast debugging with clear issue isolation Incremental PRs for each confirmed fix (easy review & tracking) Focus on stability + maintainability (not just quick patches) Estimate: First batch turnaround: 1–2 days depending on bug complexity Comfortable with ₹1,200 per fix or hourly—whichever you prefer I can start immediately and deliver the first fixes quickly so you can verify impact early. Let me know how many issues you’d like me to take in the first batch.

Spring Boot's layered architecture makes per-bug pricing clean: each defect lives in a distinct layer, so you can verify a fix in isolation before touching anything adjacent. Approach: clone the repo, reproduce each issue against the live JSON contract, then resolve in three passes. First is controller validation (binding errors, missing @Valid, wrong status codes). Second is service logic (bad business rules, incorrect transformations). Third is model and persistence (entity mapping, constraint violations). Each fix gets a pinned MockMvc test so the suite confirms nothing regressed before the PR opens. New endpoints follow the same pattern: @RestController + request/response DTOs + service method + test, batched into the same PRs so you can review piecewise. Did similar work on a Spring Boot 3 IoT API, around 18 endpoints rehabilitated over 3 weeks. Fixing one layer completely before moving to the next kept the test suite stable throughout. M1: First 5 bugs + tests, INR 7500, 4d. M2: Next 5 bugs + new GET endpoints, INR 7500, 4d. M3: Next 5 bugs + new POST endpoints, INR 7500, 3d. M4: Final pass + API contract readme, INR 7500, 3d. What's the current test coverage like, and is there a Postman collection or OpenAPI spec I can use to map expected vs actual responses before writing anything?

Your best chance of winning this project is writing a great bid proposal here! I am an experienced Java developer specializing in Spring Boot and RESTful architectures. I will quickly diagnose your legacy issues and expand your backend with clean, high-performance endpoints for your sensor data. **My Plan:** * **Debugging:** Deep audit of model classes and services to fix broken GET/POST calls and ensure schema compliance. * **Development:** Adding modular, well-documented endpoints using Java 17 and Maven. * **Testing:** Delivering robust JUnit/Integration tests for every fix to ensure 100% reliability. * **Tracking:** I am comfortable with your task-based payment structure (₹1,200 per fix/feature) to keep momentum high. **Questions:** * Are the sensor devices using a specific authentication method (like Bearer tokens or API keys)? * Do you have a preferred library for the unit tests, such as Mockito or AssertJ? Ready to stabilize and scale your API!
