About Me
Hi, my name is Wim Deblauwe, a software developer specialized in Java, Spring, and JVM related tooling.
I wrote Taming Thymeleaf, a book to learn more about using Thymeleaf with Spring Boot. I also have a few open-source projects: one that makes it easy to do Spring Boot error handling, another for integration of Cypress with Testcontainers and a few others.
I blog regularly here about Spring Boot, Thymeleaf,Asciidoctor and other programming related subjects.
