Shell International Exploration and Production [Bluware, Inc.], September 2004 - Present
Designed, built, and utilized the tools and processes integral to the consolidation, merging, and updating of approximately 30 terabytes of distributed seismic data from various applications into a centralized global file structure hosted on net appliances.
Shell Information Technology [Bluware, Inc.], June 2003 - September 2004
Worked with a security team to construct an IDS and network monitoring suite built around such tools as tcpdump, snort, and argus. Linux-based processing stacks were installed in three global data centers along with approximately 300 autonomous remote sensors at smaller installations. Analysis and reports were based on approximately 3 terabytes of full packet capture data per day. Built tools for: session correlation between RADIUS, citrix, GRE, and internal network activity; flow analysis and virus detection and propagation tracking; and full session reconstruction up to and including the application layer in some cases.
Network Security Solutions, January 2003 - June 2003
Developed the back-end scheduler, processor, and data store for a nessus remote integration tool for black-box remote sensors deployed amongst SMB's.
February 2001 - January 2003
Explored 18 countries between New Zealand and Ireland.
Shell Services International [Bluware, Inc.], November 1998 - January 2001
Deployed and supported utilities such as Perl and Netscape across a large
heterogeneous Unix network. Created a package management environment for generically
providing architecture, version, and depot maintenance across all Unix environments.
Implemented scanning tools for security baseline audits across Unix platforms.
Created framework for active system queries and analysis of approximately
1500 Unix hosts. Implemented employee-lookup bridge from LDAP repository
to legacy Unix CLI tool via a query spider.
Shell Exploration & Production [Bluware, Inc.], September 1997 - November 1998
Supported and enhanced Trap Analysis, a C++ 2D graphics program used
to determine the likelihood of hydrocarbon traps across fault faces. Supported
and enhanced CurveSpace, a C++ program used to visually compare and
process oil traces.
Shell Oil Company, Shell Services, April 1996 - September 1997
Supported, maintained, and monitored the Shell internet firewall, consisting
of parallel TIS Gauntlet proxy machines. Served as technical consultant on
numerous web and internet related projects and policies. Developed CGI/automation
solutions for web projects mainly in Perl and JavaScript, including an automatically
updated Shell service station location/map database, and a historical Shell
stock price interface based on Royal Dutch stock prices automatically retrieved
daily from the web. Deployed web applications such as Mosaic, Netscape, and
associated helper applications across heterogeneous unix network.
Shell Oil Company, Bellaire Technology Center, May 1994 - April 1996
Data Security Representative: responsible for ensuring machines were secure
from data loss due to malice (viruses, worms, hacks, etc.) or neglect (procedures,
carelessness). A variety of tools were employed at the time, including Tripwire,
Tiger, Satan, and Crack. Site webmaster: First introduced the Apache web server,
developed and maintained many automated and CGI tasks using Perl. Created
and maintained site specific web documentation. Along with other site representatives,
instrumental in introducing web technology to the Shell intranet. Introduced
SGI IRIX machines to the Shell environment, building all support infrastructure
and handling all system administration. Second level Unix support (provided
support for site system administrators) for SunOS, Solaris, AIX, and HP-UX.
Shell Exploration & Production, February 1992 - May 1994
System administrator on a variety of Unix flavors: SunOS, AIX, HP-UX. Assisted
in the design and installation of quality control network on board the Shell
America, a seismic surveying ship. The network consisted of Sun Sparc
II and IBM RS6000/480 workstations integrated with the existing Unisys data
acquisition mainframe, along with a wireless TCP/IP network connection to
workstations on a sister survey ship, the Betty Chouest. The entire
network was designed with full redundancy and hot disk replacements for minimal
downtime during surveys. Coordinated and implemented site migration of PC's
from DOS to Windows 3.1 and token ring network. Updated legacy FORTRAN programs.
Science Applications International, Inc., June 1991 - September 1991
Worked on data acquisition systems for nuclear power plants. Systems were
composed of VAX mainframes and data acquisition arrays networked with DECNET.
Designed and implemented a Novell networked CAD depot for the drafting employees.
