Mechanical ESOIs Distributing system (MEDS). MEDS application front end was implemented on Tomcat web server with

Struts framework. Back end was based on Oracle Data Base. Business logic was implemented in JAVA and it ran on a UNIX

server. I participate in all stages of this project. Full development cycle started from business requirements and completed by

production support.

• I have succeeded as an application architect in combining 7 different applications into a single one. I was able to encapsulate

differences in existing applications and fit multiple conflicting requirements in a single web application. This unified

application was rolled out for use in all regions and markets. This resulted in an increase in user productivity because the

unified application showed information from different regions in one window. Reduction in number of applications reduced

the total system support cost.

about one thousand lines of Perl to the FIRST system. LNP Development was done in Solaris OS with Sun

development environment. I wrote several resolvers as well.

Programmer Consultant, Rockwell International, Elk Grove Village, IL 04/1997-06/1999

• C, Perl, UNIX, Solaris, OS9, Embedded, Real time and Redundant systems.

• I worked to provide Automatic Call Distribution center feature enhancement and support. I analyzed current code, which

included several million lines of C code, and I provided required code improvements. The Spectrum integrated Call Center

System was built upon a distributed processing architecture designed to integrate with an enterprise computing environment

and increase the efficiency of the service representative operations. The Spectrum system can cost-effectively meet the needs

of virtually any size call center, up to 2, 400 agent positions. Spectrum is a non- blocking system that can handle call

volumes up to 25 calls per seconds (90, 000 calls per hour). These calls can involve Voice Response Units (VRUs), host

database interrogation and call transfers. Multiple units can be networked to provide automatic backup and load balancing.

The Spectrum Integrated Call Center System is a comprehensive solution for the challenges of call center management.

System functions span automated call distributions, automated voice response, data integration, and voice messaging and

automated outbound call management. Spectrum uses standard Ethernet and TCP/IP data links to permit users to implement

3rd party, best- in- class applications for CTI, data- directed inbound call routing, and automated customer contact systems

for outbound calling. Involved in the dynamic memory management, data base table expansion, and call processing.

C Senior Programmer, University of Chicago, Hyde Park, IL 03/1996-03/1997

• DEC UNIX, Linux, software development and system support. C/C++, Tcl/Tk, real time programming, device drivers.

I was responsible for general software support of the Organismal Biology and Anatomy lab in the University of Chicago. Lab

uses Alpha station with DEC UNIX, several Pentium computers running Linux Red Hat, and VAX/VMS cluster.

SYBASE project: Responsible for software and administrative support of SYBASE database holding experimental data (~ 600

M byte).

Bird song recording project, Saber: One of the OBA Lab research directions is the bird song study. Birds are kept in the sound

isolated boxes with microphones. Each microphone is connected with ADC controls via the computer. The Recording system is

based on the Pentium Pro computer with Linux OS. A maximum number of 16 channels might be connected to the ADC plug in

board, manufactured by National Instruments Inc. (at MIO 16x). To control this board we wrote a Linux driver and distributed the

on-line software system with GUI. This driver works with interrupts and used DMA channels to read from the device buffer.

Software was implemented as a client-server model. Server process ran several threads. The device thread ran code to de-

multiplex input data, put every channel in the individual circular buffer, make analysis to estimate value of every set of data, and

to record useful sound fragment on the disk. Command thread got user commands through TCP/IP sockets from the user on any

computer. GUI can reside on any computer and provided a fancy front end to Command Line Interface and also provided a

graphical data representation, which included the signal oscillograms, graph of power, and a Fourier image of the signal. GUI

was written using C, X windows / Motif, and Tcl/Tk. This project size was about 10k lines of code.

C Software Engineer, Motorola/Unisoft Consulting Co., Arlington Heights, IL 10/1994–03/1997

• C, Perl, Shell scripts, UNIX, X-windows/Motif, X- Designer, LabView.

• I designed and developed Advance Test Tools for Motorola Corporation Cell phone environment. Tools included GUI

client/server, and real-time applications. C, Perl, UNIX, X- Designer, LabView. Designed and participated in the

development of the Command Line Interface (CLI) handler to SIFT. SIFT is a proprietary Motorola system created to

simulate the traffic of the entire cellular phone networks. Originally SIFT was controlled by GUI. CLI handlers performed

commands from different software systems received through networks, and also automated SIFT control with the script. I

worked with a team of SIFT developers (five people) during four months. My next project was for integrated scripting

environment (SETT) to write a library that allowed to start SIFT and perform executing all existing SIFT command from

SETT. I wrote all necessary scripts to do basic tests. The SIFT library for SETT was written with Perl except a few C

routines which provided a socket communication. SIFT and SETT runs on Spark station with Sun OS. I worked with this

project about six months and I wrote about 6k lines of Perl code.
