I will build a spring boot rest api with validation swagger docs and docker
Mosfik
Over deze dienst
A Spring Boot API delivered to professional standards, not tutorial standards.
I have a public example of exactly this an insurance policy service with request validation, centralised @ControllerAdvice exception handling, OpenAPI 3.0 via Springdoc, JPA persistence, a consistent response wrapper, integration tests and a Dockerised environment. Ask and I will send it.
Java is where most of my work has been: Bangladesh's national Customs Bond Management System for the National Board of Revenue, and a GraphQL Backend-for-Frontend for Rakuten's e-commerce platform in Japan. 24 of my public repositories are Java.
WHAT YOU GET
Layered Spring Boot service, JPA/Hibernate with sane entity mapping, request validation with clear error messages, centralised exception handling, a uniform response shape, OpenAPI documentation your frontend team can actually use, and tests that prove it works.
Spring Security with JWT or OAuth2 if you need auth I hardened exactly that on a national compliance platform.
WORKS WITH
PostgreSQL, MySQL, Oracle, H2, MongoDB.

I build backend systems in .NET and Java. Eight .NET 9 microservices in production, 24 public Java repositories, and an open-source clean-architecture foundation for .NET 9 you can read before you order.
I also work in travel tech: a flight search fanning out to eleven GDS and supplier connectors, streaming 1,000+ live fares in under ten seconds.
Ten peer-reviewed publications, an IEEE Best Paper Award, and 78 manuscripts reviewed for international journals. I review work critically as well as writing it.
GMT+6. I reply within the hour. If I cannot do your job well, I will say so.

Veelgestelde vragen
Which Spring Boot and Java versions?
Java 17 or 21 with Spring Boot 3.x by default. Tell me if you are pinned to something older and I will confirm before you order.
Can you work with my existing Spring project?
Yes. Send the repository first and I will tell you whether it fits this gig or needs a custom quote.
Do you include authentication?
Spring Security with JWT or OAuth2 is included in Premium and available as an extra on the other tiers. I hardened exactly this on a national compliance platform.
Which databases do you support?
PostgreSQL, MySQL, Oracle, H2 and MongoDB. Others are usually fine, just ask.
Is the API documented?
Yes, OpenAPI 3.0 via Springdoc on every tier, so your frontend team can work from the spec instead of from messages to me.
Do you write tests?
Integration tests are included from Standard upward, and available as an extra on Basic.
Do I own the code? Can I use it commercially?
Yes, fully, on delivery. No licence, no attribution, no strings.
How do we communicate, and how often?
Through Fiverr, with an update every two days minimum. I work GMT+6, which is a full afternoon of overlap with Europe and most of the working day with the Gulf.
