I am your go-to Java virtuoso freelancing my way through the tech world. I whip up microservices with Spring Boot faster than you can say “Docker container,” and keep things smooth with Gradle and Jenkins. My version control is top-notch with Git, and I debug like a pro with Mockito and JUnit. For logging, I’m all about SLF4J and the ELK Stack. Agile practices? Absolutely, thanks to Jira. Let’s connect if you need code that’s as polished as my coffee machine!
