Summary of Recent Skills and Experience

Through Icon Professional I worked for NetlogicMicro providing Linux System Administration support for approximately 40 Linux servers in an environment containing Oracle E-Business Suite, Oracle Database and Various other Oracle Applications. Designed and implemented a High Availability Cluster using the Oracle Grid Infrastructure Conducted a Vulnerability Assessment using such tools as Metasploit, nmap and Openvas to determine and remediate vulnerabilities on open Internet facing ports. Provided SAN storage administration for Del/EMC Clarion Arrays.

Arcsight is a rapid growth company and a market leader in Security Incident and Event Management (SIEM). At Arcsight I was responsible for a number of areas which drew on prior experience and required learning new technologies. Linux System Administration (RedHat, CentOS, Oracle Enterprise Linux); Unix System Administration (Solaris, AIX). Storage Administration for the corporate SAN, (DELL/EMC CX3-20C) and NAS, (NetApp 270). Architect and senior support person for the backup system (EMC Networker). Virtualization (VMware vCenter ESX cluster, ESXi, StageManager/Lab Manger) Sun Microsystems (Solaris Containers).Project Management (Perforce Virtual Cluster, Corporate SAN, Stage Manager Test Infrastructure, Sun Virtualization, Oracle Enterprise Linux yum/update server. As project manager I followed corporate project management procedures and used project planning tools to successfully complete projects on time and on budget. In addition to managing the project I was also the architect, designer, builder, tester implementer and primary technical support person . I have excellent verbal and written communication skills and have developed clear thorough Documentation including design specifications, how to articles and standard operating procedures. SOX, participated in the process to become SOX compliant by creating, documenting and managing various SOX controls. Wearing multiple hats I provided IT support to Engineering, Professional Services, Customer Support, Marketing, Sales and to the IT Applications group. That support included Linux/UNIX system administration, SAN/NAS storage administration and project management/implementation.

At Blue Lane Technologies as Senior IT Engineer I met the challenge of learning new and complex technologies while facing the pressure of aggressive deadlines. As the first IT employee I became a one person IT department, providing support for a fast paced Engineering department developing a state of the art network security appliance. To support the Engineering effort I quickly learned how to build complex combinations of VMware or standalone servers and clients running Microsoft, IIS, MSSQL, Exchange; Oracle, databases, Application servers and the Ebusiness Suite; UNIX/Linux, AIX, Solaris, RedHat, OpenBSD. During Microsoft patch Tuesdays and Oracle CPU patch release cycles I installed security patches and built customized VMware hosts within the required short turn around times to support Engineering development and testing. The Engineers relied on me to provide them with all levels of support. I solved problems daily, which, if not resolved promptly, would have had adverse affects on product development schedules. I developed an automated installation process using Kickstart to build a complete product for the alpha release.

Additionally I supported Corporate IT. I Developed and implemented a data backup and recovery system. Implemented a networked UPS and power distribution system that provided battery backup, automatic system shutdown and remote power control of servers in the IT room. Provided Linux technical knowledge to the Windows corporate IT support personnel.

As an independent contractor, working through Park Computer Systems at Rambus, I used Kickstart to create an automated installation process for RedHat Linux on Dell Servers to support the migration from Solaris to Linux.

Prior to the above engagement I spent a year of intense training acquiring a number of professionally recognized IT certifications. That quest culminated in the completion of a project titled, Architecting, Designing and Building a Secure Information Technology Infrastructure, A Case Study. To fulfill the practical requirement for the GIAC Security Essentials Certification (GSEC) I built an Information Technology Infrastructure with an integrated Security Architecture.
