Summary
Jesus Herencia is a pragmatic Java developer with 11 years of hands-on experience modernizing enterprise systems across biotech, insurance, payments and automotive assistance. He specializes in backend architectures (Spring Boot, Java 17), API development, data migrations and test automation, and has led incremental migrations from Hibernate to MyBatis and Spring Boot v2→v3 upgrades in production-grade middleware. Comfortable with frontend components (Angular) and ETL tooling, he blends strong operational practice—CI/CD with GitLab/Jenkins, Sonar analysis and Flyway schema management—with agile delivery in cross-functional teams. Based in Villeurbanne, France, he pairs technical curiosity (recent data science bootcamp) with a practical focus on improving processes and observability for complex, message-driven systems. Unexpectedly, his background spans both PHP/Symfony and Pentaho ETL work, giving him breadth across web, data and integration layers.
