I will build a secure java spring boot rest API with jwt authentication


About this gig
I build secure, production-quality backend systems using Java and Spring Boot the same architecture powering real SaaS platforms.
Whether you need a REST API from scratch, JWT-based authentication, or a backend that's secure and scalable, I can help.
What I offer:
- REST API development with Spring Boot
- JWT/OAuth2 authentication and role-based access control
- Database integration (MySQL, PostgreSQL, MongoDB)
- Redis caching for faster response times
- Clean, well-documented, testable code
Recent work:
I built a multi-service fitness tracking platform with Eureka service discovery, an API Gateway, Keycloak-secured authentication, and an event-driven RabbitMQ pipeline feeding an AI recommendation engine. I also built a full-stack task manager with JWT auth, BCrypt password hashing, and Redis-cached queries that noticeably reduced repeated database load.
I care about clear communication you'll know exactly where your project stands at every step, not just at delivery. Message me before ordering if you'd like to discuss your specific requirements, and I'll make sure the right package fits what you actually need.

FAQ
What information do you need from me to get started?
Your API's purpose, the data model/entities involved, and any specific authentication requirements. A rough sketch or existing codebase (if you have one) helps too.
Can you work with my existing codebase instead of building from scratch?
Yes — send me your repo or files and I'll assess scope before we start.
Do you provide support after delivery?
Minor bug fixes related to the delivered work are included during the revision period. Ongoing maintenance can be arranged separately.
