About Javier
I’m an Oracle DBA, a proud husband, and father of three amazing boys who constantly challenge me and keep me learning every day. I am an Oracle Database Administrator with over 25 years of professional experience exclusively dedicated to Oracle technologies. My journey began with Oracle Education Spain as an instructor, and since 2002 I have been working as a freelance consultant and trainer. I hold OCP certifications across Oracle Database versions from 8i through 23ai, and I have delivered training and consulting services for both the public sector—such as the National Police, Ministry of Presidency, Tax Office, and Justice Department in Spain, as well as the Health Department in Norway—and for private corporations in industries including pharmaceuticals, telecommunications, finance, and insurance. I’m also the author of “Optimización SQL en Oracle” (in Spanish), a book dedicated to SQL tuning in Oracle. Today, I lead the Café Database initiative—a community “lounge” for DBAs and developers. Café Database includes a free Discord server, live events, podcast café-talks with Oracle (and non-Oracle) experts, a YouTube channel, a GitHub repository, and an Online Academy designed to mentor Oracle professionals and help them take their skills to the next level.
