Project details

I build production-grade REST APIs in Java and Spring Boot for startups and enterprises - the same stack I use daily on banking and fintech platforms.

What you get:
 • Clean, well-structured REST endpoints following best practices
 • Database design and integration (PostgreSQL, MySQL, MongoDB)
 • Authentication and security (JWT / Keycloak), input validation, error handling
 • OpenAPI/Swagger documentation and unit tests
 • Optional Docker packaging and AWS deployment (Advanced tier)

I'm an AWS Certified Solutions Architect (Professional) and Oracle Certified Java SE 11 Developer with 6+ years shipping resilient, event-driven microservices. You'll get readable code, clear communication, and reliable delivery. Please message me with your requirements before ordering so I can confirm scope and timeline.
