December 2011

o Designed and implemented in C++ and Matlab a medical algorithm for human

heart rate measurement using a conventional web camera to capture and

analyze series of human face images.

o Developed in C++ a psycho-physiological algorithm for classifying a

disabled human's emotions and response ( via an arousal and a valence )

by means of FLIR thermovision ( IR ) images.

Advanced Micro Controls AD SW contractor May 2011

- August 2011

o Developing GUI interfaces for IP compatible devices.

Experimental work

Juanuary 2011 - April 2011

Implementing ASP 3.5 modules in C# VS.net 2008 environment.

New Horizons Training Center January 2010 -

December 2010

o CCNA, MCSA, MCTS, MCP training

certificates earned

Freelance Custom Projects January 2009 -

December 2009

o Designed graphical display drivers and APIs for Microchip PIC

controllers.

o Designed linearizing utilities for thermocouple type temperature sensors

for PIC controllers.

o Created status symbols set for 2 line graphics displays.

Integra5 Communications Senior SW Engineer Oct. 2006

- Nov.2008

o Designed an embedded Caller ID client for Motorola Family set-top boxes

utilizing

multi-threaded and asynchronous data processing.

o Developed a Color Compression Suite allowing for 24-bit RGB to 4-bit CLUT

index data conversion( BMP-to-GIF).

o Developed a Carousel File System ( both server and client side ) aimed at

data delivery for embedded terminals with no hard disks.

o Developed a powerful TV Chat Service where multiple embedded thin clients

were communicating with one another by referencing a head-end server.

For that purpose, I designed a special communication protocol, a very

innovative

on-screen keyboard, as well as an associative server data base.

o Designed The TV Embedded Proxy bridge - a powerful service that

allowed for

remote home control using the IR blaster circuitry built in the set-

top boxes.

o Created a unique Color Symbolic TV Chat language for faster and

Native Language Independent communication ( submitted for publication ).

Smith & Nephew Endoscopy SW Contractor May 2006 -

September 2006

Designed an Embedded Terminal Image Processing GUI studio aimed at color

endoscopy

o Added Image Processing functionality to the Smith & Nephew SNE660 Medical

Imaging System using DLL technology and COM interfacing.

o Updated the DICOM images libraries.

o Improved the serial communications protocol between the CONDOR server and

the client embedded stations.

L3 Communications Ltd. SW Contractor

nanokernel. As a development system was used Linux Enterprise 4 OS.

A series of parallel port tests were performed in order to confirm

the stability of the new OS.

o A GUI-based antenna control interface implemented in Qt Designer 3.3.

Completed the basic set of control/feedback widgets, as well as the

primary signal/slot object intercommunications interface.

July 2005

My major responsibilities here covered porting MPEG-4 modules for ARM

Linux

environments.

Motorola Inc. SR Software Engineer

July 1999 - January 2005

I implemented the following major projects related to the digital network

services

and TV set-top boxes:

o A powerful client/server system interface ( in C & C++/MFC ) that

implements display memory dumps for an embedded system:

extracts ( from an embedded terminal) and sends out via RS-232 the

YCrCb data,

resolves the color transform equations YCrCb to RGB, and stores

the produced

.bmp files onto the PC HDD.

o A C++ MFC-based applications that control 32-port Rocket port board in

the

Embedded terminals reset logs collection. Wide knowledge on Windows non-

overlapped

and overlapped (asynchronous) modes, communication and worker threads

design.

o Injection and processing of MPEG-2 still pictures into Video FIFO buffers

of an embedded set-top box.

o MPEG-2 transport streams analyses: tracking Virtual Channel Map

messages/maps,

Configurations, Entitlement messages etc.

o SDK library support - IR-blasters control, and multi-point serial

interface streams control applications.

o Numerous Test Quest Pro based projects. This system sends IR signals to

the population of embedded set-tops, and then recognizes the output

pictures/text

generated by the graphics processors.

Test Quest Pro system utilizes a C-scripting language and allows for

automated

testing in weeks-long cycles of multiple ( 16, 32 etc. ) set-top

boxes.

o Designed RS232 drivers for video multiplexors Alpha 161 & Betha 161.

o Designed a powerful Pipelined Test Script Architecture that utilized test

verbs

and data base oriented control flow.

o Embedded boxes Firmware investigations and fix-ups: API servers fix-ups,

trap interface

improvements, drivers adjustment.

o Reset log analysis: I spent couple of years as an error log analyst

working for embedded boxes on per-task stack dumps and NVRAM records.

Systems covered: 32-bit Motorola

68xxx, and 64-bit MIPS 4000 ( VR5432, VR5500).

o Performed numerous RTOS analyses: memory allocators, queues and stacks

implementation.
