Oracle 11.2 SQL Certified Expert
Oracle 11.2 PL/SQL Certified Professional
fan of SQL tuning, PL/SQL tuning
some bits of experience with SQL-Plus, SQL-Loader, ...
some bits of experience with C#, Oracle Data Provider for .NET, PHP
some bits of experience with BASH, GREP, GAWK, SED
other than that, just an ordinary Oracle DB dev with too little time nowadays
mainly answering interesting and mind-exercising questions, since there are just too many Lalit Kumar B's these days striving so much for answering the beginners' stuff, climbing to the tops of the answer stacks, stealing others' reputation for themselves :-) ... and I simply have too little time to mindlessly compete with these modern sharks
