I will build rest apis and kafka microservices


About this gig
Got a backend service to build? I'll get it done.
I build production-grade Java microservices using Spring Boot and Apache Kafka. Whether you need a REST API, an async event-driven pipeline, or a full service with persistence and messaging - I'll design it properly and deliver working, tested code.
What I can build for you:
- REST and SOAP APIs with Spring Boot
- Kafka producers, consumers, and stream processors
- IBM MQ and RabbitMQ integrations
- Persistence layers with PostgreSQL, MongoDB, or MySQL
- Payment and banking service integrations (XML/XSD)
- Unit and integration tests with full coverage
I've built payment microservices for a major US bank and high-throughput signalling services handling 100k+ TPS. You get the same standard of work regardless of project size.
Message me before ordering so we can scope it right.

FAQ
What information do you need to get started?
A brief description of what the service needs to do, your preferred Java version, database, and any messaging system involved (Kafka, IBM MQ, etc.). If you have existing code or an architecture doc, share that too.
Do you write tests?
Yes. All packages include a working test suite. The Premium package includes full unit and integration test coverage.
Can you work with an existing codebase?
Yes. Share the repo and I'll review it before we agree on scope.
What Java versions do you support?
Java 8, 11, 17, and 21. I'll recommend the right version based on your stack.
Do I get the source code?
Yes, full source code is delivered for all packages.
Can you integrate with third-party APIs or payment systems?
Yes. I have hands-on experience with payment integrations including REST, SOAP, and XML/XSD-based systems.
What if the scope is larger than your Premium package?
Message me before ordering. I handle larger projects through custom offers.
