I will build a secure spring boot rest API with jwt authentication
Ezzat Mohamed
About this gig
I'll build you a Spring Boot REST API that's ready for real use, not a tutorial project.
WHAT YOU GET
- Clean REST endpoints with correct HTTP status codes
- Database layer with Spring Data JPA: PostgreSQL, MySQL or Oracle
- Request validation with clear per-field error messages
- One consistent JSON error format across the whole API
- Interactive Swagger docs your frontend team can actually use
- Database migrations, so your schema is reproducible
- Automated tests
- Docker Compose, so it runs on your machine in one command
Standard and Premium add JWT authentication with roles and permissions.
I START FROM A TEMPLATE I ALREADY BUILT
github.com/ezat141/spring-boot-api-starter - auth, validation, error handling, migrations, docs, tests and Docker are already solved and tested. Your money goes to your features instead of plumbing.
Clone it and run docker compose up to judge the quality before you order.
For businesses and startups. I don't take academic assignments.
Message me what you're building and I'll tell you which package fits.

I'm a Java backend developer. I build Spring Boot REST APIs and fix broken ones, and my specialty is API security: JWT, OAuth2, roles and permissions, multi-tenant systems.
Most of my work is on banking and payment systems, where a bug is a financial event rather than a ticket. So I reproduce a problem before I touch it, and I write a test that proves it is fixed.
You don't have to take my word for it. My code is public: github.com/ezat141/authcore is a full OAuth2 server with 65 tests that you can clone and run in two minutes.

FAQ
Will I own the code?
Yes. You get the full source in your own repository, with no dependency on me. I'll also include a short README explaining how to run it and where things live, so another developer can pick it up.
Can you add to my existing project instead of starting fresh?
Usually yes — send me the repo and I'll tell you honestly whether it's cleaner to extend it or start from the template. If your project is on an older Spring Boot version, say so up front, as that affects the estimate.
Which database do you use?
PostgreSQL by default, but MySQL and Oracle are equally fine — I work with all three. If you already have a database, I'll map to your existing schema rather than replacing it.
What if I need more endpoints than the package covers?
There's an extra for an additional 5 endpoints, or message me first and I'll send a custom offer sized to what you actually need. I'd rather quote accurately than have you buy the wrong package.
