I will build a scalable backend api with java spring boot and kafka
Piyush D
About this gig
Looking for a reliable backend developer who actually understands how systems work under load not just how to make an endpoint return 200 OK?
I'm a backend engineer specializing in Java and Spring Boot, with hands-on experience in Kafka, Redis, PostgreSQL, and MongoDB. I build REST APIs and backend systems that are structured properly from day one: clean architecture, sensible database design, and code that's easy to hand off or scale later.
What I bring to your project:
- Clean, well-documented REST APIs built with Java & Spring Boot
- Proper database design (PostgreSQL / MongoDB)
- Authentication & authorization done correctly
- Real-time features using Kafka where they're actually needed
- Redis caching for performance-sensitive endpoints
- Postman collections / API docs so your frontend team isn't guessing
I've built and shipped a real-time payment fraud detection platform end-to-end (Spring Boot, Kafka, Redis, PostgreSQL) and have merged open-source contributions to the Bisq project so this isn't theoretical backend knowledge.
I communicate clearly, deliver on time, and won't disappear mid-project. Message me before ordering if your requirements go beyond what's listed

I am a Computer Science student with backend engineering experience in Java, Spring Boot, and distributed systems like Kafka and Redis.

I am comfortable building scalable, multi-tiered backend systems and working through ambiguous technical problems.
FAQ
Do you write frontend code too?
My core focus is backend — Java, Spring Boot, APIs, databases. I have working knowledge of React and can integrate with a frontend, but for dedicated frontend/UI work I'd recommend pairing me with a frontend specialist.
Can you work with my existing codebase?
Yes — send me access or a repo link before ordering and I'll confirm scope and timeline based on what's already there.
What do I need to provide to get started?
A clear description of what the API/backend needs to do, any existing database schema or requirements, and access to relevant accounts (database, hosting) if applicable. If you're not sure what you need, message me first and I'll help scope it.
Do you provide the source code and documentation?
Yes — full source code and a Postman collection or API documentation are included with every package.
