. I am smiling in the picture below, because when it was taken, Lisa and I had just hauled our bodies up to the Harding icefield near Seward, Alaska, after I retired from doing the stuff listed below, in 1999.
 

EXPERIENCE:

1995-May 28, 1999: Senior Network Specialist, Technical Support Group, Telecommunications, Global Information Systems Department, Texaco Inc.

Note: I am now retired from Texaco Inc. I spend my time playing. My motto is, "Capital should work. People should play."

Lead engineer in a group supporting a corporate Wide-Area Network composed of 350+ routers connected by ATM switches, frame-relay switches, and conventional digital circuits, as well as LANs based on both shared and switched infrastructures.  Extranet connections to 45+ other companies.  Configuration of firewall routers on inter-company networks as well as the dual-homed company Internet connection.

Network-specific training courses, all from American Research Group: Introduction to Cisco Router Configuration, Advanced Cisco Router Configuration, Introduction to SNMP, Internetwork Design, Cisco Router Security and Performance Tuning, Advanced Border Gateway Protocol, LAN Switching (Cisco 5500, 5000), ATM.

Relevant buzzwords: Cisco routers, ATM, frame-relay, Cisco LAN switches, Catalyst 5500, VLANs, EIGRP, IGRP, OSPF, BGP, RIP, Novell IPX, TCP/IP.
 

1993 - 1995: Consulting Systems Engineer, Information Technology Department, Texaco Inc.

Application of computer technology to real-time instrumentation systems, including the following:

A graphics display package for a custom NEC Class-I display terminal used on Texaco production platforms, written in 80X86 assembler.

A DDE-server to acquire data from Elliott Gas Flow Computers and make it available to network clients, written in Microsoft Visual Basic.

1977 - 1993: Senior Research Electrical Engineer, Bellaire Research Laboratory, Texaco Inc.

Development of microprocessor-based instrumentation and control systems, including the design of interface hardware as well as software development using structured analysis and design techniques and CASE technology, including the following:

An X.25 packet-radio-based data acquisition and control system for remote natural gas pipeline compressor stations, including programming of an RTU-board to act as a router/controller for the packet radios, and development of Modbus protocol software for the RTU.

Real-time process control and data acquisition systems utilizing PLCs interfaced to PCs using Windows DDE drivers, with display and control applications written using the Intouch Man-Machine Interface and Excel spreadsheets.

A marine geophysical data acquisition system utilizing a multiport time-division multiplexor and custom TTL-I/O to acquire, store, reformat, process, and output data to other onboard computer systems. Software written in Pascal, with interrupt and console drivers written in assembler.

A laboratory data acquisition system to acquire analog and digital data from instruments, perform calculations and store the results for in-system processing and remote transmission.

A HASP-synchronous/asynchronous protocol translator to allow a graphics terminal to be connected to a CDC mainframe as a high-speed batch terminal device.

Hardware Design Experience:

80X86, 6800, 8085, VAX, TTL, Multibus, PC-ISA, Intel & Tektronix development systems with In-Circuit Emulators, modems, packet radio data systems.

Software Experience:

Most recently: HTML Web page construction, Visio, Microsoft Project, Microsoft Office. Less recently: Pascal, C, C++, FORTH, PL/M, Fortran, Assembler, Basic, Unix, MSDOS, Visual Basic, Lotus 1-2-3, Excel, RBase 5000, Focus, Oracle, Accelerator CASE, EasyCASE, synchronous and asynchronous communication protocols (including asynchronous file-transfer protocols), Pagemaker, AutoCAD, TurboCAD, Windows, Word-for-Windows, Lotus Notes, Wonderware Intouch MMI. Unix, including not-recent experience as a Unix sysadmin.

Education: University of Texas, B.S.E.E. 1977. If you want to know why I list my degree as E.E. despite having taken a lot of courses in the C.S. department and having spent much of my subsequent working career writing software, see The Difference.

Professional Associations: Member, Institute of Electrical and Electronic Engineers. Member, International Hoplology Society. Member, Space Access Society. Member, International Defensive Pistol Association. Member, Appalachian Trail Association. OK, some of those aren't really professional associations, in the sense that I'm not interested in those activities with respect to a profession - but I am more interested in them than I am in working for money.

Personal:

Radio Amateur, Extra Class Station License AK5N. Interests: antenna design, packet radio. Sea-kayaking, backpacking, scuba diving, sailing. Also iaido, aikido, long-distance rifle and pistol shooting. We live in an RV parked somewhere in the western hemisphere.
