Mr. Warshawsky is a computer systems software expert with 20 years of experience
in systems programming and administration, and application software development.
While specializing in UNIX systems and networks, he also has a breadth
of experience with personal computers, IBM mainframes, and a variety of
other platforms. In his spare time, he sings with classical choral and
acapella doo-wop groups.
Mr. Warshawsky has spent much of his career in research and engineering
computation center environments, which exposed him to a wide variety of
technical challenges.
As a systems programming consultant, Mr. Warshawsky was assigned for
6 ½ years to AT&T Bell Laboratories. There he was involved in
one of the early efforts to port the UNIX system to mainframe computers,
and later supported a network of 5 Amdahl mainframe UNIX (UTS) systems.
He developed a high-speed network to communicate with an IBM mainframe,
created a subroutine library to control a StorageTek automated tape library,
and assisted with the design of a high-performance front-end processor.
He made system enhancements which averted the purchase of additional equipment.
During 7 years on the staff of a large university, he installed and
maintained the mainframe (MVS) operating system and made numerous enhancements
to its time sharing system (TSO). He supervised 2 programmers and was responsible
for acquiring software products.
RELEVANT EXPERIENCE
Computer Associates International – Senior Programmer; 1995 – present
Mr. Warshawsky added Unicenter message logging to the AutoSys job scheduling product and ported the product to Linux systems.
Mr. Warshawsky assisted early adopters of CA-Unicenter TNG with installation
and configuration. He developed HTML filters and CGI scripts to permit
creation of Unicenter event management reports via the World Wide Web.
He automated the customization of Netscape, Sun, and Apache HTTP servers
for Unicenter TNG WorldView. He boosted the performance of the WorldView
back-end on UNIX platforms. He prepared custom HP-UX and Linux packaging
of the Unicenter TNG Framework so the operating system vendors could include
the product in their distributions.
To support these projects, Mr. Warshawsky expanded his local network to
include Solaris, HP-UX, Linux, Windows NT, and Windows 95 machines.
Mr. Warshawsky added support for large StorageTek tape libraries to the
CA-Unicenter Open Storage Manager product. He assisted and advised customers
on using the product in high-performance and high capacity environments.
Legent Corp. – Development Advisor; 1994 – 1995
As a member of the Open Storage Manager product development team, Mr. Warshawsky
established a framework for automated product testing using ETET. He transformed
existing tests to fit the new framework. He then led other developers in
using and building on the new framework.
After Legent entered into an agreement to resell Spectra Logic's automated
backup software, Mr. Warshawsky acted as the technical liaison between
the two companies. He modified the product to meet Legent's requirements,
including private branding.
Mr. Warshawsky also established a connection to the corporate IP network
to support telecommuting, and administered small heterogeneous subnetwork.
Systemhouse Inc. – Technical Architect; 1993 – 1994
Mr. Warshawsky's last assignment at SHL was to re-engineer a heterogeneous
network of more than 50 computers to improve performance, reliability,
and ease of maintenance, and to align with corporate standards.
He wrote significant portions of a proposal to GFI Genfare to produce a
new data system for transit authorities. He then designed how the application
system operates on the host UNIX system, installed and maintained the development
environment, and implemented several of the system's components.
Mr. Warshawsky was a senior team member on two projects for IBM. One project
involved writing automated procedures to test system administration functions
of AIX. The other project was to port system administration functions used
by SMIT from AIX to SunOS and HP-UX environments.
INTERACTIVE Systems Corp. – Principal Member of Technical Staff, Project
Manager; 1989 – 1993
As a Principal Member of Technical Staff, Mr. Warshawsky participated in
the preparation of a Preliminary Architectural Design Specification for
the Image Archive Subsystem of a proposed document processing system for
the IRS. This project used CASE tools for Structured Analysis.
Mr. Warshawsky managed the relocation of a 40-person software development
office to a new facility. This involved specifying telephone, network,
and security system requirements, selecting vendors, supervising construction,
and planning the move.
As a Project Manager, Mr. Warshawsky managed all aspects of small consulting
projects. He participated in sales calls and in writing proposals, arranged
contracts, and assigned and supervised technical staff. He also managed
technical staff on long-term client-site assignments. This required interviewing
client supervisors to appraise employee performance.
Lachman Associates, Inc. – Member of Technical Staff; 1984 – 1989
As part of his responsibilities in UTS Systems Support for AT&T Bell
Laboratories, Mr. Warshawsky designed and implemented a high-performance
device driver for channel-to-channel adapters. He then modified the UNIX
operating system's Remote Job Entry subsystem to communicate via CTCAs
with IBM mainframes using Network Job Entry.
Mr. Warshawsky implemented a set of library functions to allow UNIX application
programs to gain access to a Storage Technology automated tape library.
This system used remote procedure calls to communicate with the Sun server
which controlled the tape library.
He was also involved in the following tasks: designing a high performance
from-end processor for UTS; developing device drivers and debugging tools;
diagnosing and repairing operating system faults; modifying operating system
memory management functions to reduce real memory consumption; instructing
client staff on the IBM 370 architecture; planning new equipment configurations
and supervising their installation; identifying and eliminating throughput
bottlenecks in NSC Hyperchannel and Ethernet networks.
He was a UTS systems consultant for Amdahl Corporation. He supported client
installations, bug fixes and general on-site support services.
Cademic, Inc. – Chief Software Engineer; 1983 – 1984
As one of the founders of the company (a start-up venture specializing
in computer assisted design of VLSI ICs), Mr. Warshawsky designed and supervised
the implementation of a portable Computer-Aided Design system for Very
Large Scale Integrated Circuits. This system consisted of a graphical editor,
logic and timing simulators, an optimizing silicon compiler and ancillary
software tools. All of the software was implemented in C on a UNIX time-sharing
system. The software for the design phase was transported to a microcomputer
running CP/M-68k. The silicon compiler produced both nMOS and CMOS logic
circuits. He managed a team of six Software Engineers and supervised the
operation of the Seventh Edition, System III and 4.2BSD UNIX operating
systems on Cadlinc, Plexus and DEC computers, respectively.
