Over deze dienst

Need a reliable Java backend for your app or platform?

I'll build or fix a secure, production-grade Spring Boot REST API clean, tested, and ready to scale.

I'm a Senior Java Developer with 12 years of backend engineering experience at Facebook, Amazon, and J.P. Morgan.

I focus on writing maintainable, high-performance APIs that follow best practices in security, logging, and error handling.


What I can do for you:

  • Build new REST endpoints (Spring Boot, JPA, Lombok, Swagger)
  • Add or fix JWT / OAuth2 authentication
  • Troubleshoot backend issues and exceptions
  • Optimize performance and database queries
  • Review and refactor existing Spring Boot projects


Tech stack expertise:


  • Spring Boot / Java 17+
  • JWT / OAuth2 Security
  • REST / GraphQL APIs
  • SQL / JPA / Hibernate
  • AWS Deployment & CI/CD


Why clients choose me:


  • Enterprise-level experience, startup-friendly delivery
  • Clean, well-documented code
  • Fast, clear communication
