About this gig

Still running Spring Boot 2.x? It's end-of-life, and upgrading can feel overwhelming but it doesn't have to be.

I've performed a full Spring Boot 2.x to 3.x migration in a production fintech environment, handling everything from namespace changes to AWS SDK upgrades. I know exactly where the pain points are and how to resolve them efficiently.

What I cover:

  • javax jakarta namespace migration
  • Spring Security 5.x 6.x configuration updates
  • AWS SDK v1 v2 migration (including DynamoDB Enhanced Client)
  • Spring Cloud compatibility upgrades
  • Redis Jedis Lettuce migration
  • JAXB and XML binding plugin updates
  • Dependency conflict resolution
  • Full regression testing & validation

I don't just do a mechanical upgrade; I review your codebase, flag deprecated patterns, and suggest improvements along the way. You'll end up with a cleaner, more modern codebase that's ready for Java 21 and beyond.

Whether your app is small or enterprise-scale, I'll handle the migration carefully and thoroughly, with clear communication throughout.

Send me your project details, and I'll give you an honest assessment of the effort involved before you commit to anything.
