- Software Engineer,
worked on the Platform Team for the Juniper EX Switch Platform series
- Created 32-bit and
64-bit x86-based bootable disk images of the EX software that ran in
Virtual Machines. Tested
with QEMU, VirtualBox, and VMWare.
Images had the full JUNOS Command Line Interface (CLI) and were
used for testing, and for CLI training.

NAND Flash File System for FreeBSD developed by Semihalf
( http://semihalf.com ) into JUNOS
- Work spanned:
kernel, userland, startup scripts, and file
system unit tests
- Build engineer on for
the JUNOS network operating system, derived from FreeBSD.

a modified FreeBSD make utility with hooks into the FreeBSD kernel to
optimize the the software build of JUNOS.
- Presented work at BSDCan conference, Ottawa, Canda,

Principal Software Engineer
March 2004 to
- Obtained MPEG-2 video
data from the IPV SpectreView
video server, and wrote C++ code using the AAF Toolkit in Linux to
encapsulate the video data inside MXF metadata files. The MXF files
could then be imported into the Avid MediaComposer
- Performed sustaining
engineering on the Avid Mediacomposer video
editor product in Windows using Visual C++. Focus areas were in
import/export of video data using the MXF metadata format and the AAF
- Worked on the Avid AirSpeed video server product.
- Developed an
On-Screen Display for AirSpeed in FreeBSD and
C++. Based on user input from a front-panel with play/stop/record
buttons, the program would pop up an On-Screen Display on the AirSpeed LCD. Menu selections such as Brightness/Contrast, were processed using the
"Command" Design Pattern in C++.
Input commands from the front-panel were read in user-space from an
input serial port, and commands to display the OSD were sent via an
output serial port to a Techwell 8800 OSD.
- Rewrote the installation
process for AirSpeed. Converted installer from extracting a
simple tar, to a scripted installer which installed system components
which were FreeBSD packages created with pkg_create.
University Extension School

Systems Programming course.
- Answered technical
questions via e-mail and in-person.
- Corrected assignments
written in C under Digital Unix and Linux. Marked code based on style
issues and correctness, but also looked at robustness, resilience to
errors and failures, and memory management.

Audio/Video Streaming Service
- Performed low-level
protocol analysis and system troubleshooting of RSVP and Diffserv QoS network
protocols in the ACE and TAO libraries using the Ethereal protocol analyzer.

capability to decode Real-time CORBA priorities values in GIOP headers.
- Performed C++
TAO/CORBA development for the Joint Tactical Radio System (JTRS)
project. Performed team mentoring for development team

Infrastructure (GNI) telecommunications network at Verizon's Verizon
- Performed AIX Unix
administration to ensure correct levels of compilers and system
libraries were installed
- Wrote an Inprise Visibroker CORBA
process in C++ and Java to interface with legacy telecommunications
systems and deliver real-time network alarms to system. Real-time alarms
were obtained from legacy system over Unix
named pipes and sockets. Historical alarms were obtained from Informix
- Wrote a C++ program
using RogueWave libraries to interface with a
trouble ticketing system
- Fixed a freeware C++
program Ethereal (a network
protocol analyzer) so that it would compile and run under AIX. Needed to

BIG DATA INTERESTS
am currently interested in research and learning about Big Data, and pursuing
any opportunities in this space. I
strongly believe that Big Data combines technology such as storage, networking,
distributed systems, and algorithms in a unique way which can make businesses
more competitive and increase business efficiencies.
research into Big Data has so far involved the following, primarily on the DevOps and administration side of Hadoop:
