You will get Spring Boot REST API Development — Secure, Documented, Production-Ready
Project details
I'm a Java backend developer with 3+ years of hands-on experience in fintech — building APIs, card management systems, and authentication flows that handle real financial transactions.
What I work with:
• Spring Boot, Spring MVC, Spring Security
• JWT, OTP, role-based access control
• JPA / Hibernate, MySQL, PostgreSQL
• RESTful API design + Swagger/OpenAPI
• Microservices architecture
• Git, Maven, basic CI/CD
I take on freelance projects that align with my core expertise — backend APIs, authentication systems, and database-driven applications. I'm not a jack-of-all-trades; I focus on what I do well.
If you have a Java backend project — new or existing — let's talk. I'll give you an honest assessment before we start.
Response time: within 1-2 hours (Pakistan Standard Time, GMT+5).

Steps for completing your project
After purchasing the project, send requirements so Ahmad can start the project.
Delivery time starts when Ahmad receives requirements from you.
Ahmad works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements & scope review
I'll start with a short call or chat to understand your project what endpoints you need, your database setup, authentication requirements, and any third-party integrations. I'll confirm scope before, so there are no surprises later.
Architecture & API design
I'll share a simple outline of the API structure — controllers, services, entities, and database schema — before building. This gives you a chance to review and request changes early, before the work is done.
