I will develop java spring boot rest apis and backend modules
Zhe X
About this gig
Need a Java backend feature with a clear handover? I have 10 years of Java development experience, including e-commerce backends and legacy-service migration.
I will build a focused Spring Boot REST API or backend module for your application. We agree the endpoints, data model and acceptance criteria before work starts.
Your delivery includes:
- Java source code for the agreed scope
- One database integration within the stated entity limit
- Request validation and consistent error responses
- API documentation or a Postman collection
- Local run instructions and verification notes
Packages cover a small, agreed feature, not a complete website. One endpoint means one HTTP method and route. Authentication, payment flows, complex business rules and deployment need separate scoping. Frontend design and hosting fees are not included.
Please message me with your requirements and existing code, if any, before ordering so I can confirm the right package. Revisions cover the agreed scope, not additional features.

I am a Senior Java Backend Developer with extensive experience in delivering e-commerce systems, migrating legacy services, and building reusable backend components. I have a proven track record of coordinating cross-functional teams and integrating AI applications into multimodal workflows. I am comfortable owning backend delivery and working across the full development lifecycle. Personal AI-assisted projects include English-learning apps, comic/short-drama workflows and an open-source LLM course platform. These are prototypes or personal-use projects, not client deployments.

FAQ
What should I send before ordering?
Send your requirements, expected behavior, technology versions and relevant code or API docs. Remove passwords, tokens and customer data. I will confirm the scope and suitable package before you order.
What does a revision include?
A revision is an adjustment needed to meet the original agreed requirements. New endpoints, integrations, changed business rules or unrelated issues need a separate scope.
Can you work on an existing Java project?
Yes. Please provide relevant code, build and run instructions, dependency versions and a clear description of the change. We need a reproducible development or test setup.
Are frontend work, hosting and production deployment included?
No. Packages focus on Java backend development. Frontend work, hosting and third-party fees, infrastructure setup and production deployment are excluded unless explicitly agreed in a custom offer.
