* Developed a system for analyzing the techno-economic indicators of a thermal power plant, and I created a fuel consumption optimization system for the thermal power plant. This system has shown proven economic benefits and is operational in 25% of power generation companies in Russia (C# + MS SQL Server/Oracle).* Additionally, I introduced and managed Agile methodologies within the company, facilitating regular releases and the rapid distribution of the product (Scrum, Kanban, MS TFS).

* Development of algorithms for clustering and indexing of complex graphical information. * Development of algorithms for segmentation of human faces and human skin in images. * Data analysis, preparation of visualizations and scientific reports (MATLAB, Oracle, C++).* Defended thesis for the degree of PhD in Technical Sciences

* Enterprise development of multidimensional data processing software for automatic generation of complex reports for the energy industry (custom in-house developed OLAP based on Oracle Database).* Development of Web application for reports generation. C# (ASP.Net) + Oracle.
