He was AMAZING. Actually taught the concepts rather than just doing it for me. Had me doing to logic, queries, and deep stuff while he helped me with the stuff I was absolutely lost on (such as Swing.....) Thank you so much!!

Provided excellent explanations of Java, JavaFX, and Database concepts, whilst being patient with someone just starting out learning programming. Would recommend to any prospective student looking at starting out on their learning journey learning java.
