Official Maintainer of PL/Java

I have been programming in C since the mid-90s.  I've done programs, extensions, and shared libraries for DOS, FreeBSD, Illumos, Linux, and Windows.  I've used almost all C compilers and debuggers that are still relevant today, including Borland (now Embarcadero), clang, GCC, Intel, Visual Studio, and Watcom.

Database administration, including backups and recovery, point-in-time-recovery, and first time installations; database tuning.  

Client development in C, C++, Java, and Python; to name a few.
