I will build a secure rest API backend with java spring boot
Younes B
About this gig
Your backend is the part your users never see and never forgive. I build it properly.
WHAT YOU GET
A Spring Boot REST API written in Java 17/21, structured the way production code should be: controller / service / repository layers, DTOs instead of leaked entities, Bean Validation on every input, and real error handling that returns useful messages instead of a 500 stack trace.
Every delivery includes a Postman collection so you can test it immediately, and a README that tells your team how to run it.
STACK
Java 17/21 - Spring Boot 3 - Spring Data JPA / Hibernate - Spring Security + JWT - PostgreSQL or MySQL - Swagger/OpenAPI - JUnit 5 + Mockito - Docker
WORK I HAVE SHIPPED
A microservices video-streaming backend and a LeetCode-style platform with sandboxed code execution - both public on my GitHub, both built on this exact stack. Ask and I will send links.
HOW I WORK
I ask questions before I write code. If your requirements are half-formed, that is normal - send what you have and I will tell you what is missing. You get progress updates, not silence.
Message me with what you are building and I will tell you honestly whether I am the right fit.

I build backend systems that hold up in production - not demos.
My core stack is Java 17/21 with Spring Boot and Spring Cloud: REST APIs, JWT security, microservices with Eureka, API Gateway, RabbitMQ and Redis, all containerised with Docker. I've built a video-streaming platform and a full LeetCode-style judge system on that stack, both on GitHub.
I also work in Laravel, MERN and Django when a project calls for it, and in Angular or React on the front end.
You get clean, documented, tested code, a Postman or Swagger collection, and clear communication in English, French or Arabic.

FAQ
Do I get the source code?
Yes. Full source code, yours to own, delivered as a Git repository or a zip archive. No hidden dependencies on me.
Can you work with my existing database?
Yes. Send me the schema or a dump and I will map the JPA entities to it rather than forcing a rewrite of your data.
Will you connect the API to my frontend?
API work is this gig. Wiring up a full frontend is my full-stack gig, but if it is a small integration I will usually just do it. Ask me first.
Do you write tests?
Unit tests with JUnit 5 and Mockito from the Standard package up. Integration tests are included in Premium.
What if I need changes after delivery?
Revisions are included with every package. Beyond that, message me - I fix genuine bugs in code I delivered without charging you for it.
