I will build kafka event driven microservices with java and spring boot


About this gig
I build complete web applications with a Java Spring Boot backend and a React frontend - from database design to a working, deployed product.
What you get:
- REST API built with Java 17 and Spring Boot 3
- Clean, responsive UI that works on mobile and desktop
- Database design and integration (PostgreSQL, MySQL, MariaDB or MongoDB)
- User authentication and role-based access control
- Unit tests and OpenAPI documentation
- Docker setup so the app runs the same on every machine
- Full source code, yours to keep
My background: I work as a backend engineer on a production microservice platform built on Apache Kafka, Redis and multiple databases. Your app gets built the way real production systems are built - proper error handling, retries and tests - not a demo that falls over on the first real user.
Message me before you order and tell me what you want to build. I will tell you which package actually fits, or tell you straight if I am not the right person for the job.

FAQ
What do you need from me to get started?
A short description of what the app should do, any design or screenshots you already have, and which database you prefer. If you are unsure about the database, I will pick one and explain why.
Do I own the source code?
Yes. You get the full source code with every package, and it is yours. I keep no rights over it.
Can you work with my existing project instead of starting from scratch?
Often yes, but message me with a look at the codebase first. I will only take it on if I am confident I can work in it cleanly.
What happens if I need changes after delivery?
Each package includes revisions. Beyond those, you can add an extra revision, or message me and we agree on a custom offer for larger changes.
