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.

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
