I will develop a scalable java spring boot backend rest api and microservices
Maneesha G
About this gig
Your backend is the part that fails at 2am. I make sure it doesn't.
I'm a backend engineer specializing in Java and Spring Boot - the stack that runs banks, not weekend projects. I build secure, scalable REST APIs and microservices with clean architecture, tests, and proper deployment.
WHAT I BUILD
- REST APIs with Spring Boot and Spring Security (JWT/OAuth2)
- Microservices: API gateway, service discovery, event-driven design
- Database design and integration: PostgreSQL, Oracle, MySQL
- Message brokers: Kafka, RabbitMQ, Redis caching
- Dockerized deployment, Kubernetes, CI/CD pipelines
WHAT YOU GET EVERY TIME
- Clean, documented, tested code you fully own
- Swagger/OpenAPI docs and a Postman collection
- Deployed and running, not just handed over
- Daily updates and a walkthrough on delivery
I have built a multi-tenant fintech backend with 15 modules, audit logging and role-based access. Enterprise standard, freelance price.
MESSAGE ME BEFORE ORDERING with your requirements or existing codebase. I will reply with an honest scope, timeline and price - usually within the hour.
Let's build a backend that lasts.

FAQ
Do I own the code and documentation?
Yes, 100%. You get the full source code, repository, Swagger docs and a Postman collection. No lock-in and no dependency on me afterwards.
Can you work with my existing backend or codebase?
Yes. I audit your existing codebase first and tell you honestly whether to build on it or refactor - including when a rewrite is the wrong call.
Which package do I need?
Message me first and I will tell you straight. Basic is a single API, Standard is a full backend, Premium is microservices and infrastructure.
Do you write tests and documentation?
Yes. Every package above Basic includes unit and integration tests, plus Swagger/OpenAPI documentation and a ready-to-use Postman collection.
Can you deploy it with Docker and Kubernetes?
Absolutely. I set up Docker, Kubernetes and CI/CD, and deploy to AWS, GCP or your preferred host. Available as an extra or built into Premium.
What happens after delivery?
You get a walkthrough video and full documentation, and I stay available for questions. I also offer monthly maintenance for ongoing support.
