Who is Rafael del Nero?

I’m a Java Champion, senior software engineer, and the creator of the Java Challenger initiative.

Over the past 15+ years, I’ve worked as a Java developer in Europe while contributing to the global Java community as a speaker and author. I’ve written books such as Java Challengers, Java Algorithms Interview Challenger, Java System Design Challenger, and Golden Lessons.

Through mentoring intermediate and senior developers, I’ve helped engineers transition to international roles, increase their salaries, and compete at a higher technical level.

Today, my focus is simple: helping experienced Java developers understand where they stand and what they need to reach the next level in the global market.
