PROFILE
Sean Ruffatti
Sean Ruffatti contributed to the openrewrite/rewrite-spring repository by delivering a series of migration and compatibility features focused on Spring Boot and Spring Cloud upgrades. Over four months, he developed automated migration recipes and updated dependency management to support transitions from Spring Boot 3.4 through 4.0 and Spring Framework 7. His work included refactoring build configurations, generating migration properties, and ensuring observability by updating Prometheus metrics integration. Using Java, Groovy, and YAML, Sean emphasized test-driven validation and code migration strategies, resulting in a stable upgrade path for downstream users and reducing risk and effort for teams adopting new Spring platform versions.

Oct 1, 20252025-10 monthly summary for openrewrite/rewrite-spring: Key delivery focused on migration support for Spring Boot 4 and Spring Framework 7. No major bugs reported this period. Core accomplishments include delivering boot4 migration recipes and properties, updating dependencies (Jackson v3 and JUnit 6) within the migration path, generating migration properties for release candidates, and preparing a Spring Framework 7 recipe outline. Added automated tests to verify boot4 recipe configuration. This work reduces upgrade risk and time for customers upgrading to Spring Boot 4 and Spring Framework 7, and strengthens OpenRewrite's position for Spring migrations. Demonstrated skills include recipe-based migration tooling, code generation, packaging changes, test automation, and cross-team collaboration (Co-authored by Sean Ruffatti and Tim te Beek).
