You will get Secure & Scalable Spring Boot REST API with Authentication + Health Checks


Project details
You will get a secure, production-ready Spring Boot REST API built with clean architecture, versioned endpoints, OAuth2 / JWT authentication, and health checks — the exact foundation modern applications need to scale confidently.
With years of hands-on experience in building robust microservices, API gateways, and authentication systems using Spring Boot, Docker, and cloud deployments, I ensure the APIs I deliver are secure, maintainable, and integration-friendly.
Whether you're a startup, enterprise, or solo developer, this project provides:
🔐 Strong security with proper authentication & authorization
🧱 Clean, well-structured codebase for easy extension
🌐 Seamless integration with any frontend or 3rd party services
🚀 Deployment-ready package (Docker / Kubernetes optional)
I don’t just deliver code — I deliver a reliable backend foundation that accelerates your product’s growth.

About Sachintha
Java Backend Developer | Spring Boot, Docker, Kubernetes, AWS & APIs
Galle, Sri Lanka - 4:32 am local time
I'm a Backend Developer who builds reliable APIs in Java/Spring Boot and Python/FastAPI, and rescues the ones that are quietly falling apart. If your backend is slow, buggy, or scary to deploy, I can help.
What I build for clients:
REST APIs that handle real traffic (Spring Boot, FastAPI)
Database layers that don't choke under load (PostgreSQL, MySQL, SQL tuning, indexing)
Clean Docker + Docker Compose setups your team can actually maintain
Kubernetes deployments and troubleshooting
AWS deployments with NGINX, Redis, and proper reverse proxy configs
Third-party API integrations that don't silently fail
Backend automation scripts that save your team real hours
Where I tend to add the most value — real-world debugging:
Session handling and autosave issues, token expiry bugs, Tomcat misconfigurations, Gradle build problems, slow queries in production, containers that work locally but break in K8s, reverse proxy headaches. The kind of issues that aren't on Stack Overflow.
How I work:
Clear, frequent communication — you'll always know where things stand
Clean, maintainable code — no shortcuts that haunt you in 6 months
Honest timelines — I tell you what's realistic, not what sounds good
I finish what I start
Tech I work with daily:
Java, Spring Boot, Python, FastAPI, PostgreSQL, MySQL, Redis, Docker, Kubernetes, AWS, Linux, NGINX, REST APIs, SQL.
Whether you need a new API built from scratch, a production bug fixed before it bites you again, or someone to clean up a messy deployment — send me a message describing what you're working on. I'll reply with honest thoughts on whether I'm the right fit and how I'd approach it.
