I will build scalable java spring boot backend microservices


About this gig
I'm a backend engineer who builds production-grade Java Spring Boot microservices for real businesses, not tutorials or toy projects. I currently work as a Backend Software Engineer at a global card-issuing and payments processor, where I design and ship microservices that handle real-time transaction processing, fee collection, and billing at scale.
What I can build for you: REST APIs and microservices with Spring Boot (secured with OAuth2/JWT), database design and integration (PostgreSQL, MySQL, MongoDB), payment and fintech-style backend systems, Dockerized services ready for AWS deployment, and performance tuning for high-volume workloads.
I write clean, tested, documented code and communicate clearly throughout the project. Whether you need a single microservice or a complete backend architecture, I deliver systems built to scale, not just to demo.
Let's talk about your backend requirements.Skills:
Java, Spring Boot, Hibernate/JPA, REST APIs, PostgreSQL, MySQL, MongoDB, Docker, AWS, Microservices
Why Me:
- Reasonable Price
- Reusable Scalable CLEAN Code
- Customer Satisfaction
