Leading a self-directed team in a growth oriented company in the technical/e-commerce/infrastructure computing area(s) located in the Dallas/Tulsa/Oklahoma City/Kansas City Metropolitan areas. I prefer a wide range of work that will utilize my existing skills and allow me to expand my knowledge and abilities

Bachelor of Science in Mathematics, University of Oklahoma, 1991

Amerada Hess, Houston, TX 1991-Present

I am currently the Unix Technical Lead for Amerada Hess U.S. Exploration and Production Technical Computing in Houston, Texas.

My current responsibilities include the design, installation, support, and cost effectiveness of a enterprise comprising 300 servers, 200 desktops, 100 Terabytes of storage, 40 tape drives, multiple 1 Gigabit and 100 Megabit networks and switches. I have day to day responsibility for a 248 node Linux cluster, 25 Linux servers, 2 Apache Servers, 15 Linux desktops, various applications, and several in-house written programs and scripts. Our Linux projects have resulted in savings of 3 million dollars. These systems require detailed knowledge of the kernel, RAID, networking, file services, file systems, DNS, NIS, Security, Hardware, scripting, c programming, web development, backups, programming, and tuning. In addition, I participate in the planning, implementation, and secondary support of 20 Solaris servers, 2 Auspex NAS servers, 2 Network Appliance NAS servers, and 130 Solaris desktops. The Sun systems have special requirements such as Oracle, Geoquest, Veritas, and fiber optic storage (T3 Arrays). Additionally, I also use various means including Samba, Unix printing, and Pam to integrate our Unix environment with our Windows/NT/2000 environment and provide consulting to our various offices around the world including work with SAP, Oracle, Networking, and R&D projects.

Over my 11 years at Hess, I have gained excellent experience in all areas of IT/IS. I have worked on various Unix hardware and software platforms including HP, Sun, SGI, and IBM. These systems scale from the lowest end Suns to large-scale Sun E4000s, Sun E450s, SGI Powerchallenge, and IBM RS6000 SPs. I have also worked on Dell and Compaq servers and desktops and various other clone platforms. I have installed and maintained Linux and various Windows versions. In most cases, I provided sole support for all aspects of the hardware and software on these platforms. I have also managed several million dollar projects from inception to final completion.

I have developed a detailed knowledge of the inner workings of most IT infrastructure areas but have spent a lot of time supporting business units from technical and business areas. In addition to my normal duties, I have written many programs, web applications, and scripts using C, TCL/TK, Perl, HTML, MySQL, and shell commands. I also participated in our company's projects involving the Intranet, firewall, wireless networking, PDAs, VPN products, multiple projects involving Business Process improvements.

My experiences also include extensive work with documentation, user training, image editing, management presentations, budgets, long term planning, project management, purchasing, vendor negotiation, resource allocation, remote office coordination, personnel evaluation, group leadership and employee guidance. Several of my projects have resulted in multi-million dollars savings for Hess.
