Developed principal functionality for a password management application using MS Visual C++. Implemented Internet Explorer/Firefox extensions and windows hooks to conveniently fill web forms and application prompts. Implemented interprocess communication between password detection modules and the main program.Extended a personal data encryption application. Introduced additional authentication methods using MS CryptoAPI. Added secure remote administration interfaces suitable for corporate deployment. Automated daily build smoke tests using VMware VIX API, TestComplete, and Ranorex.Supported an enterprise mail management system that prevents unauthorized mail access.Supported an enterprise business intelligence product.

Protected user workstations - about 2000 Windows computers, mostly connected to the local network. Developed a general security policy to streamline security efforts. Cleaned different computers (that were unprotected) from viruses and other malware, configured software to prevent future infections and returned computers to operation. Provided security information, recommendations and news for users and local administrators. Organized relevant security updates for OS, applications and protection software to ensure automatic updates and to simplify manual patching. Monitored network for dangerous activity and investigated suspicious machines.

Refactored core of a fixed assets accounting program (five years in production and maintenance) written in Clipper using an object oriented extension library o:Clip. Wrote large amount of test code that prevented new bugs. Developed and implemented data integrity and forms access framework using organization preferred FoxPro. Brought to the development team a coding standard, pair programming, collective code ownership and object oriented responsibility distribution to increase software quality and project robustness.

Coded automation programs for an accounting department using FoxPro with MS SQL, Clipper and DBF database files. Solved problems inherent to development in network/multi-user environment.

Lead developer on a team of two conducting Windows application development.Radiokarta is a radio system for GSM network analysis and radio coverage prediction for the local GSM service provider Utel.Researched and developed a radio wave propagation model using information from a digital map.Developed and implemented using MS Visual C++: a module that reads data from GPS and GSM hardware receivers, a persistence subsystem to store program information in XML and binary files, a module for measured data analysis using Matlab graphics and statistics toolbox capabilities using Matlab C API.Applied unit testing and dramatically reduced programming errors and debug time, which was extremely important for release builds. Upon completion and implementation of basic requirements, an operational application was delivered to the client. Continued work with the client adding functionality based on the initial specification and emergent requests.Radiotochka is a real-time radio system designed to track movement of fire fighters during training.Adapted and implemented a position location algorithm using distance measurements from ultrasound sensors.Developed and implemented using MS Visual C++: display of calculated personnel positions and a building map on screen, concurrent data acquisition from hardware, position calculations and user interface operations using several threads with Win32 API.
