Skill	Experience	Level	Last Used	Description
Access	3 yrs	1.0	2006
Application Design	5 yrs	5.0	2005	Development a tool for commercial Geo Informational System Scale. Customer: Institute of Geo Informational System Problem: Creating system for finding the optimal structure for pipe nets, road nets and shortest paths on a real map. Language: C++. CASE: Rational Rose, ERWin Other: FireBird, MFC, STL, MS Project 2003. Role: Project Manager. Developer. Duration: 1 year. Abstract: The problem was actually from the following items: Research. Develop appropriate algorithm for the problem. Existing methods are not suitable for this task, because the size of the real maps. I introduced an original algorithm for solving this problem which combines advantages of the existing methods with the restrictions which poses the problem itself. Implementation. I used effective data structures for accessing the data such as binary heaps, quadra trees, RB trees. Optimization. I used Intel VTune profiler to find out bottlenecks of the program created. And I wrote some parts of the problem in assembly using MMX, SSE, SSE2 technologies. Integration into the global project. Testing During working on this project I wrote some articles about results achieved which were published in some scientific magazines. And others
Assembler	5 yrs	5.0	2005	Development of Audio codec for the security system. Problem: Introduce audio codec compressing audio stream(20-22000Hz) online with only ~0.25 msec computational time on average computer, supporting all possible formats, merging into the global project (interaction with the other developers). Language: C++, Assembler. Other: SSE, SSE2, MMX, 3D-Now, MS Project 2003. Role: Developer. Duration: 6 months(including research time and integration): Abstract: The codec created was based on MPEG-1 audio codec. Codec was completely written in Assembly to achieve required speed and have an appropriate quality
