I'm not sure I'd quantify things with "Expert" or "Intermediate". "Working Knowledge" is OK to indicate exposure to something, I guess.
As with many of the other resumes here, you don't give any details. "Java code development" could mean that you wrote 10 lines of code or wrote ten systems at a million lines each. What did the systems do? What value did you add to the project? "Project estimation" doesn't make much sense.
