EXPERIENCE -

Senior Software Engineer, Oracle Corporation (formerly Sun Microsystems), February 1999 - present (2011)

• Improved performance of Solaris crypto algorithms by tuning C source and replacing with 64-bit assembly language (AES, RSA, RC4, MD5, SHA1, SHA2)
• Secured Sun's ILOM service processor software (Linux-based) by auditing code and running system. Closed network ports, adjusted configuration, and tightened file permission.
• Secured Sun's Logical Domains software by providing user-based authentication, audit trail logging, and auditing of the Solaris-based control domain.
• Designed and develop enhancements to Solaris Security Toolkit (SST), which "tightens up" and verifies network, filesystem, and Solaris operating system security. Modified SST to compily with Center for Internet Security (CIS) standards.
• Worked on fault management software to record and recover from hardware errors (mostly memory and CPU).
• Programming at Sun Microsystems on their large-scale systems, Sun Fire 15K and Sun Enterprise 10000. Develop software which handles booting, hardware control, and diagnostics for a multi-domain Solaris platform running 1-18 copies of Solaris. Used Solaris, Linux, C/C++, Java, Korn shell/Tcl/Perl script, WBEM, SNMP, and NTP protocols.

Consultant, Stellcom Technologies, July 1998 - January 1999

• Worked on a project at SAIC to set up a packet-based TCP/IP phone network for Level 3 Communications. Used NetExpert to manage and monitor the routers, switches, DACS, and other telephone and data communication hardware. Wrote perl scripts that modified NetExpert Oracle databases using a CGI front-end generating HTML which may be displayed with a web browser. These scripts made NetExpert rule writing easier by searching for and removing unused variable and class names. Wrote a C program to redirect TCP/IP port I/O, for NetExpert debugging and testing.

Consultant, Tek Systems, Dec. 1997 - July 1998

• Programming at Sun Microsystems on their mainframe-class Enterprise 10000 systems. I fixed bugs and added features to the SSP (System Service Processor).

Senior Programmer/Analyst, Blue Bird Computer Systems, Jan. 1988 - July 1997

• Developed server software for document imaging client/server software, ImageAble. Focused on TCP/IP communications, porting to IBM's UNIX, AIX, and optical jukebox server. ImageAble is based on a product purchased from SAIC, Mosaic, that was originally hosted on an IBM VM mainframe. To help understand the product (and to help others), I wrote the ImageAble Technical Reference. I ported the part of the server dealing with communications. I striped out the IBM PWSCS communications code and replaced it with industry-standard TCP/IP sockets. I also added error handling, better messaging, installation scripts, and interrupt handlers to make it more robust, serviceable and UNIX-oriented. I wrote optical jukebox software that communicated with third-party SCSI drivers and with the ImageAble server. Ported ImageAble to SCO UNIX, HP-UX, Siemens Pyramid OSx. After release, I maintained the entire server product, including the embedded SQL code. I helped system engineers configure and setup the system. ImageAble is written in C, SQL, and shell scripts.
• Built Intranet with TCP/IP network servers (web, ftp, DNS, e-mail, time etc.), and routers. Created web server with HTML, perl, Java, and shell scripts, CGI, and HTML.
• Developed Business BASIC compiler/runtime, BASIX, to run on multiple platforms (Unix, DOS). Bluebird purchased a company in Nashville that developed a Business-BASIC compiler running on DOS. My assignment was to port the compiler to run on IBM's AIX and SCO UNIX and to enhance it to be compatible with Bluebird's Business BASIC running on it's proprietary O.S., SuperDOS. I moved project to Carlsbad, phasing in a new team of people I lead in Carlsbad.
• Enhanced Bluebird's SuperDOS file I/O performance with a disk cache. SuperDOS is a multi-user PC-hardware-based proprietary O.S. (that predates MS-DOS). The enhancement originated from a customer complaint about poor application performance. I investigated and isolated the problem to a bottleneck in disk I/O waits by SuperDOS. I proposed and implemented a solution that cached disk sectors in memory. The caching was transparent to application programs. Received "Analyst of the Year" award from Bluebird for this work.
• Ported C and Pascal compilers to SuperDOS. Wrote C library to simulate POSIX interface. Modified SuperDOS to support C and Pascal. I was hired and given a year to do it. I investigated and decided the fastest way was to license a DOS-based C compiler from MetaWare and port the runtime libraries and compiler to SuperDOS. The runtime libraries handled disk, console, and terminal I/O, the filesystem, clock, date/time, and heap and stack management. I greatly enhanced the previously out-of-date SuperDOS Technical Reference to help understand the SuperDOS. I replaced the DOS-based runtime libraries with SuperDOS calls. I modified SuperDOS to handle missing functionality, such as lower case filenames, loading 386 LDT segment descriptor tables, and C signals. Ported both C and Pascal compilers to run on both DOS and SuperDOS, and ported an Intel linker to SuperDOS. Traveled to several customer sites to help port C applications to SuperDOS. Received "Rookie of the Year" award from Bluebird for this effort. Compiler and runtime are written in Pascal, C, and x86 assembly. SuperDOS is written in x86 assembly.

University of California, San Diego Extension, Jan. 1987 - Dec. 1987

• Taught classes in C programming.

Senior Principal Programmer Analyst, NCR, Sept. 1978 - July 1982, Aug. 1984 - Jan. 1988

• Worked in Advanced Dev. simulating an instruction set for performance improvement. This was for their new 64-bit microprocessor. I took an out-of-date and hard-to-maintain simulator used for their 32-bit microprocessor and made the code more robust and maintainable and added the new instructions and word-lengths required by the new instruction set. I wrote probe-code for the new instruction set and suggested changes to enable compilers to generate more-efficient code. Simulator is written in NCRL, NCR's enhanced system programming language based on Pascal.
• Worked in O.S. file management on NCR's mainframe O.S., VRX. Fixed bugs in file management and optimized tree-structured filesystem with caching. Coded in assembly and Pascal (NCRL).
• Wrote setup/monitor software for a LAN network gateway on NCR's Tower UNIX. This was a special 1-year project in South Carolina. Software greatly eased configuration of the network gateway.
• Ported UNIX libraries/commands to NCR's 32-bit RISC hardware, MIPS. Stabilized and configured prototype system software. Coded frequently-used runtime libraries in microcode. Modified various commands to run on MIPS UNIX. This was part of a team of 10 people.
• Designed, implemented, and documented the runtime library for NCRL on NCR's VRX mainframe operating system. The library handled file and terminal I/O, clock, semaphores, and interrupts and exceptions. Wrote interfaces to O.S. and runtime support (file and memory management, messages, and object format). Wrote code generators for pointers to functions and I/O statements. This was part of a team of 5 people.
• Wrote a symbolic interactive high-level source debugger. Designed, implemented, and documented the debugger, written in NCRL. Interfaced with a virtual machine running on VRX using special object
