  G5

  (Information Technology and Services industry)

  June 2007 — December 2007 (7 months)

  Creation of a system for reducing a message size and mobile traffic between server and mobile phones.
  
  Developed architecture of mail system for mobile devices. Ruby on Rails was used as a Web framework, MySQL - as a data storage, and BRDB with OCFS were used as scalable network file systems. I used SMPPLIB library (that implemented protocol SMPP 3.4) to send SMS. Changed a pop3 proxy server (3proxy.ru) to provide a possibility of adapting the emails (as well as connections with POP3S servers) and transfer reduced emails to a mobile client using protocol POP3.
  
  Environment: Linux, Python, C/C++, Ruby on Rails, MySQL, Nginx, smpplib, 3proxy, pythonxml2

  Premium Games

  (Information Technology and Services industry)

  May 2006 — June 2007 (1 year 2 months)

  Development of a cross platform graphics engine based on OGRE (open graphic rendering engine) to provide visualization of a slot machine game process.
  
  Increased functionality of a Maya exporter to meet customer requirements. The exporter made transformations from the main Maya scene graph to the OGRE binary format. It also exported graphic objects into XML "dotscene" file format that kept the position of objects in the scene, including information about physical properties of the object.
  
  Patch for OGRE in Raycasting function with changing algorithm:

  KSI

  (Information Technology and Services industry)

  July 2004 — May 2006 (1 year 11 months)

  Development of a cross platform OpenGL graphics engine for slot machines.
  
  Created an exporter of geometry and animation based on Maya three-dimensional modeling package. Several internal Maya nodes were developed to display text and font in real time. Also I created a cross platform library to work with exported binary data. The OpenGL graphics engine was used in more than ten games. It also was used to support CgFX and physical technology based on Newton library. Corrected a few bugs in the DevIL graphics library (see http://openil.cvs.sourceforge.net/openil/DevIL/src-IL/src/il_dds-save.c?r1=1.38.2.1&r2=1.38.2.2). An algorithm of motion blur using 3D texture, with CG realization on GPU has been created too.
