Carlos Sierra has written many other great scripts and utilities. You can easily verify that by giving the keyword csierra in metalink and see the results. You'll find a lot of scripts starting with prefix bde_. I wonder what that stands for. The coe in the scripts stands for Center of Expertise as mentioned in Metalink Note:190124.1 which is a white paper on performance. One more metalink note 169935.1 is on Troubleshooting Oracle Apps performance issues which says:

Carlos Sierra

Apps Engineering CoE

Oracle Support

I think Carlos has written very good scripts and anyone interested in performance tuning and tracing should always keep a lookout on Trace Analyzer and all the other great scripts and utilities written and continuously enhanced by him.
