Marina Brown's Resume

Career Summary:

OBJECTIVE:

ACCOMPLISHMENTS:

• I created the Unix and Linux Infrastructure of Surferz.net, a local ISP covering the New York Mid Hudson region. I implemented security policies for Surferz and another area ISP to prevent unauthorized accesses and to stop repeated computer break-ins on co-located servers. My security audits focus on timely patches, logfile analysis, network traffic analysis , traffic filtering and identifying habitual security violators. As a system administrator I over-saw and supervised forensic analysis of compromised hosts, and tracked security violations locally and internationally using all available means including computer and phone switch logfiles. I wrote scripts to allow tech support to do much of the everyday system administration.
  
  
• At Princeton Telecom , I maintained and administered the Unix telephone answering systems in an electronic banking and telecommunications business that transfered 3-10 Million Dollars daily. The Voice Response units were handled by Apex software and Dialogic T1 phone cards. The data from phone transactions was stored in Oracle and Informix and was processed and transmitted using heterogenous network running NOVELL, Windows NT , Windows 3.11 and UNIX. PTC's clients used a wide variety of formats ranging from Mainframe Reel to Reel tape to email or serial data connection varying from rz/sz to T1 data and serial connections. In addition I administered a DEFINITY PBX in all aspects from adding new cards to recording announcements and administering features. I was responsible for network and telephone wiring. I wrote a custom pager script that insured around-the-clock service from 4 UNIX servers and notified the appropriate system administrator of what problem had arisen. I created and administered a Tape library to insure data security in a mid-size electronic banking and telecommunications company. I was responsible for Oracle installation on an HP server and was key in the transition from a legacy Horizon PBX to a modern Lucent DEFINITY (system 75) PBX. I designed a shared NOVELL/NFS system to allow users to transmit files through a Unix dial-up server to a NOVELL environment. I wrote multiple load balancing shell scripts on SCO UNIX servers. I have managed the creation of multiple web sites and the administration of Apache, Netscape and thttpd webservers.
  
  
• I reverse engineered a custom VRU (Voice Response Units) written in Informix-C and ported it to Oracle. This project made use of extensive automation with Perl to insert comments to numbered voice prompts and required close cooperation with systems to ensure compatibility with the Definity PBX. In a related project I implemented a large part of the back-end CGI and forms for a pay-by-Internet program that used a Sun-Solaris machine to post and retrieve data from Informix servers also used for VRU payments.
