I’m Rafael del Nero, a Java Champion and creator of Java Challengers. With 15+ years of experience delivering senior‑level solutions in international teams across Europe, I understand what global companies expect from high‑level Java engineers.
Since 2020, I’ve mentored dozens of mid‑to‑senior developers to land international roles, both remote and abroad, many significantly increasing their compensation by aligning with global evaluation standards.
Today, I focus on helping experienced Java engineers compete beyond their local market and position themselves for high‑level international opportunities.
