About this gig

Stuck on a bug in your Spring Boot API or React app? I'll reproduce it, fix it with a minimal, clean change, and add a test that proves it works.


What I work with every day:

  • Java 21, Spring Boot, Spring Security, JPA/Hibernate, Flyway
  • React (Vite), Node.js/Express
  • PostgreSQL, MySQL, Docker, GitHub Actions


You'll also get a short explanation of what caused the problem, so it doesn't come back.


Please message me before ordering with a short description and access to the repository, and I'll confirm the right package.
