About this gig

Hi, I'm Janeck, a dual-study computer science student in Hamburg and an apprentice software developer at Star Finanz, a fintech company that builds banking software for Germany's Sparkassen (savings banks) network. On a daily basis I work with Java, Spring Boot, and MySQL in a production environment with high standards for code quality and security.

I can help you with:

  • Building REST APIs and microservices from scratch
  • Extending or fixing bugs in an existing Spring Boot backend
  • Designing and connecting MySQL databases
  • Code reviews and refactoring

I write clean, well-documented, and tested code, following the same quality standards used in professional CI/CD pipelines (GitLab CI, SonarQube). Communication is important to me I'll keep you updated throughout the project and ask questions upfront to avoid misunderstandings later.

Send me a message with your requirements before ordering, so I can make sure your project fits the selected package. Looking forward to working with you!
