I have been a senior software administrator in New York University's Information Technology Services since March of 1997. My responsibilities include:

• Project Lead, High Performance Computational Cluster, a top500 installation at NYU. My work entails being the technical lead for installation and system administration of this 512 processor cluster as well as for several other smaller clusters.
• Lead Developer of NYUSMS - a high speed session management system for web systems with a multithreaded SSL based server written C, Apache client module, perl client module, dynamic link library, NS Messenger server client, XML configuration system and test scaffolding.
• Development Team Member of NYU's next generation Campus Portal, a web based supercomputer application.
• Perl and SQL programming for NYU's campus wide portal systems.
• Stress and Reliability Testing Network and Web Applications.
• Lead Developer of Curly tester using techniques borrowed from high performance scientific computing on large Linux clusters.
• Compiling, Maintaining and writing web server modules for a number of Apache and Stronghold web servers running on High Speed Alpha and Sun computers. This includes security programming with Kerberos.
• Working with mainframe programmers to maintain an integration of mainframe applications and a secure web gateway running on a Unix machine.
• Writing custom programs to provide web access to MySQL and Oracle databases using Perl's DBI architecture.
• Participating in NYU's emerging technology reviews. I have been evaluating Internet audio and video technologies as well as IP telephony.

• NYU High Performance Computing Cluster: I lead NYU's installation efforts to partner with IBM to install a 512 processor scientific computing cluster using xcat, compiling C and Fortran programs using xlf and xlc as well as gcc. I also implemented job management using Maui and torque.
• Benchmarking and porting cluster: In partnership with IBM, I am the NYU lead for a project to port open source software to run on the Power PC architecture.
• Another recent research project I led at NYU involved creating an open source web application tester by using high performance parallel computing techniques using MPI and collaborating via extreme programming methods. We also evaluated remote real time collaboration techniques.
• My Open Source project, Streams On Line provides a literacy learning environment. Funded by the Waterways Project, Streams On Line is a database driven collaborative writing environment that allow different schools to do literacy collaboration over the Internet.
• The Hemispheric Institute operates a virtual classroom project for which I am the technology architect. Servers installed at several different Universities throughout the Americas are joined into a network which overcomes the obstacles of international connectivity allowing web services, chat, audio and video to be used from a fast local resource.
• I worked though non-profit organizations as a consultant in New York City's Schools installing up Linux servers, setting up Internet connectivity using Network Address Translation techniques, setting up Samba services, Apache web servers and Squid proxy services. I also coach teachers on how to administer their Linux sites. Along with my wife, I started a project called LXK12.org which brought volunteers into New York City High schools to provide technical support.
• I taught a course called WWW server administration. This 24 x 4hr session course taught people how to set up and operate a web site as well as how to produce web content and how to do simple perl programming for the web.
• We installed LRW.NET's site nine years ago as well, offering web authoring as well as special Internet services, programming and workshops.
• Another research project I led was in a special area of Internet Search Engines. I wrote a new spider which uses text analysis techniques borrowed from the humanities to establish the topic of documents with mathematico-linguistic computation.

I administered the Ramat-Negev FreeNet which is based on a Sun Ultra 1 running Solaris 2.5 and Linux 1.2 server machines. I was also responsible for several Cisco 2500 routers with a number of frame-relay connections and a bank of Modems as well as Linux servers operating in local schools. I wrote cgi-bin programs and inspected any executables for use on the FreeNet's Unix machines. I programmed management tools using SNMP and TACACS.

The mandate of the Ramat-Negev FreeNet is to operate a model community network in order to establish community networking in Israel and introduce Internet to the desert area population. I succeeded in these mandates. Other community networks are beginning to appear in Israel.

There were also Linux machines in local schools for which I provided technical support and programming services. As an extension of this work, I built a collaborative system for the High School for Environmental Studies at Sede Boker. This system is designed to facilitate collaboration among students at 6 different high schools on 6 different continents. I created a WWW interface into a database system that uses SQL and full text search engines to allow each student to locate other students according to common interests and concerns. The searching student could click on the other student's URL or "mailto" and immediately establish communication. These tools were used in conjunction with IRC (typewritten chat) and CuSeeMe (videoconferencing) to allow the students to work together. I produced these systems through a collaborative relationship with the instructors who use them. I learned to value that particular process.

In addition to educational and community settings, I also built a firewall for Atid Melig Company of Tel Aviv. This experimental Linux based facility is a packet-filter firewall that provided an inexpensive effective way for a corporate intranet to connect to the Internet. A "One Time Pad" facility I put in allows a virtual private network to branch offices.

I have BSD experience from the year that I operated a site for the West Coast Internet Cooperative in Vancouver, BC. This site was an experiment by a group of 40 or so small businesses and individuals who banded together and acquired dial-up and co-location Internet services at a time when these services were very difficult to obtain locally. I wrote HTML and cgi-bin materials as well as administered the BSD system.

I did operating systems programming on Mark Williams Company's COHERENT product in 1992 - 1993. COHERENT is a Unix clone operating system. I created a TCP/IP networking system for Coherent. I learned the TCP/IP protocols in great detail.

From 1987 until 1995, I worked at Kekuli AV Society, an Instructional Media production house. I started as a photographer and moved into video production and multimedia. I produced some 30 instructional videos aimed at Health Care professionals in Canada. I was the coordinator of the Society for a year, which placed me in charge of financial management, marketing and fund raising. This organization has since changed its name to Community Care Education Society. Their web site is http://www.portal.ca/~cces/
