Open Code LLC, Samara, Russia – Specialist of Software Dev. Department Dec 2009 – Jul 2010
The company develops reliable IT solutions for government and public administrations, medical institutions, cultural organizations, electronic libraries, logistics and manufacturing. In fact, the previous company was divided and I was moved to this company with my project. So, the main project and responsibilities are the same in general, but I worked on my own project mainly. Main responsibilities:
• Develop code with algorithms and design patterns to meet required requirements and performance.
• Refactoring and supporting of legacy code.
Key Contributions:
• Designed and developed a software on Delphi for "Internet Kiosk". It is a software-hardware complex based on PC and WinXp with touch screen. It was made as stand-alone terminal for public places and was managed by special environment "Site Kiosk". So, end-up user could use a browser only and certain web application. I designed and developed a multithreaded application which allowed the browser to work with peripheral devices via ActiveX objects and JavaScript. The app had separate module for every device and used RS232 interface to communicate with devices. So, web application was able to manage contactless card-reader (NFC), magnetic card-reader
(ICT3K5-3R6240), money receiver (CCNET protocol), receipt printer and security device SFOUR "Sphere" to control physical integrity of the terminal with different sensors (Humidity, Temperature, Doors state, Watchdog timer etc.). Also, it included web-server (Indy components) for remote monitoring physical conditions and management.
• Implemented a migration from Turbo Delphi to Delphi 2010 which is based on Unicode strings. Tools, Software & Technologies: Delphi, Multithreading, Indy, RS232, COM, ActiveX, Java Script, SVN, C# SEC “Knowledge Genesis”, Samara, Russia – Specialist of Software Dev. Department Jan 2007 – Dec 2009

• Develop code with algorithms and design patterns to meet required requirements and performance.
• Refactoring and supporting of legacy code.
Key Contributions:
• Designed and developed a Java library based on POI 3.0 to generate Excel report files from Java code at server side based on SQL request. It used an excel file with keywords, formatting and styles as a template to fill out the report tables. Also, the template can contain formulas which are transformed accordingly to the data tables growing. The main advantage of the library was the ability for data tables to grow in both directions, by rows and by columns at the same time with using custom format and style for each cell.

The company develops technical and software tools for automated control and measurement systems, as well as electronic components of experimental systems.
Main responsibilities:
• Design and development of software components of various software-hardware systems.
• Develop code with algorithms and design patterns to meet required requirements and performance. Key Contributions:
• Designed and developed a software for PC for experimental system to detecting cables which was buried under water. The application was connecting to an antenna via RS485 interface by Modbus protocol. The antenna had a micro-controller which read data from 10 electromagnetic sensors and convert them to our format. The software was reading the data and drawing graphs for every sensor in real time. The shape of graphs and values were supposed to calculations determinate the distance from the antenna to the cable.
• Designed and developed a software to control the process of gathering mail from physical mailboxes. I had designed and developed a DB and architecture of application. The system was consisting of application for PC which collects data from mobile devices called "frames". Every such "frame" contained micro-controller and was used for extracting the mail from mail box and used RS232 to connect to PC. Every mailbox had an RFID tag, and every time the "frame" was used to extract mail it remembers the RFID of mailbox and current date time. I designed the exchange protocol between PC and "frame" with cooperation to micro-controller team. The software was able to build and print different reports
• Designed and developed special protection which allows to control the installation of the software by keys. It was based on encrypting some procedures in application binary file by information from linking stage. So, installed app has limited functionality, and it generates the ID number which depends on version of application and HDD serial number. This ID is used to generate a key to unlock the full functionality.

Samara State Technical University, Samara, Russia – Master of Science in Engineering Sep 1998 – June 2003
GPA: 3.7
As a qualification work, an algorithm of adaptive discretization of a deterministic signal in real time has been developed. The algorithm takes in account the relative error of the ADC and allows effective filtering of the signal. As a part of this algorithm, a technique for calculating the discretization steps by Nyquist-Shannon sampling theorem into a variable step size for restoring the original signal by Lagrange’s polynomials with a given relative error in real time has been developed.
Also, I designed and developed a software package to visualize the process of calculating the step of sampling and reconstructing the signal. The program complex allows to vary and test different combinations of parameters and could be used as laboratory work for students.
