Victor Rentea (2017)

Victor RenteaThe Clean Code Guy

Java Craftsman. Sr. Engineer & Technical Lead at IBM Romania. Independent Trainer & Coach. I worked hard on backend systems over the last 10 years, solving technical challenges of a broad range of enterprise Java applications as a developer, lead and consultant. 4 years ago, after I had devoured Uncle Bob’s Clean Code book, I joined the ‘coding craftsmanship’ move. Of course, soon after I started preaching about it as an independent trainer/coach. This Clean Code, TDD, Pair Programming stuff it’s just too fun too keep it for oneself. For hundreds of days I’ve spread the word to more than 1000 trainees in all kinds of settings (even faculty lectures), usually bundled together with other training modules that I’ve gradually developed, such as Spring, JavaEE, JPA, Design Patterns, and the like. You can find the entire curricula on my website. My extensive experience as a trainer allowed me to refine a very entertaining presentation style, spiced with jokes, non-IT-world analogies, and examples that is able to make any developer profile understand even the most advanced design discussions. Recently however, I realized how much I enjoy meeting smarter people, so I’ve started talking at international conferences such as Devoxx MA and VoxxedDays Bucharest and Belgrade, and I am so enthusiast about meeting you guys, too !

I am a professional Java Developer working in the software development industry, with more than 8 years of experience in business areas like Finance, Insurance and Government. I have finished my degree in Informatics Engineering (equivalent to the Bologna Master’s degree) from the Department of Informatics Engineering of the University of Coimbra in 2006, however I started to learn and enjoy Java in 1998. I work with many Java based technologies like JavaEE, Spring, Hibernate, GWT, JBoss AS and Maven just to name a few, always relying on my favorite IDE: IntelliJ IDEA. As a Freelancer / Independent Contractor I travelled around the world (an old dream) to customers, but also to attend Java conferences. The direct contact with the Java community made me want to become an active member in the community itself. For that reason, I have created the Coimbra Java User Group, started to contribute to Open Source on Github and launched this blog, so I can share some of the knowledge that I gained over the years. I hope you find it useful! Currently, I’m working with Tomitribe. After working for a few major corporations, I’m eager to help and grow something from the ground up. I’m very excited to work with all the amazing tribers working hard to make TomEE a compelling Java EE server.
