FAQ
Can you modernize a large legacy Java application?
Yes. I can assess the existing system and create a practical incremental modernization strategy without requiring a complete rewrite.
Do you recommend rewriting the entire application?
Usually not. I prefer incremental modernization based on business priorities, technical risk, and the actual architecture.
Can you migrate from older Java/Spring versions?
Yes. I can help plan and implement migrations to modern Java and Spring Boot versions.
Can you migrate a monolith to microservices?
Yes, when microservices are actually justified. I can identify suitable boundaries and define an incremental migration approach.
Do you also implement the modernization?
Yes. Premium packages can include implementation of a selected component, while larger migrations can be handled through a custom offer.
