I have experience in working with libraries: Devart, DeveloperExpress, Telerik, Infragistics, Aspose and create own libraries and elements.

I have practical experience of creating complete cycles  of commercial products:
  - The creation and coordination architecture
  - Functional and technical specifications
  - Development in groups and individual
  - Automated and manual testing

    Server 2003-2012R2)  and various versions of desktop Windows       
    (Windows95-Windows 8.1)
   -  automatic updates systems creation

    WPF / Silverlight
Experience  of about 6 years. I have worked with versions 3.0 - 4.5
I know the patterns of MVVM, PRISM. In recent years, WPF has been my main technology for creating user interfaces.

    VB 6 / VB.NET
Experience  of about 7 years. I have worked with versions  VB 6.5 - VB.NET 4.0
I have experience of conversion and adaptation of old applications written in VB 6 application to VB.NET-C # VB.NET-C#

    ASP.MVC / HTML / CSS / Java Script / Jquery / Bootstrap
Experience  of about 6 years. I have diverse experience creating websites for selling and supporting products  as well as the development of sites of medium complexity for small firms. Have sufficient experience in the use of development tools for graphic design.

    SQL / LINQ / Entity
I have experience with different drivers, interfaces and protocols to work with various types of databases and data sources of different formats. In recent years, I mostly use Entity framework versions 4.0 - 6.1 

The most significant projects:

      During 2014-2015 years in Progressive Solutions Europe Ltd, London  I participated in the development:

     Sequoia EPR  - corporate information system for centralise procurement department and control the entire life cycle of a transaction from purchase order to payment of the invoice and synchronise with accounting software (http://www.pseurope.com).

In this project I was responsible for the following tasks:

Responsive web-design for mobile and tablet devices 
To solve this task, I used the technology: Bootstrap v3.1, Jquery v2.1, Ace v1.3, CSS3 

Refactoring and code optimization to improve performance 
   The project applied the technology AJAX to real-time activity reports, tracking and tracing statuses and location of orders, vehicles and people. 

       During 2012-2014 years in Nebula Data Exchange Ltd, London  I developed:
 
The Program for financial analysis and evaluation of the effectiveness of economic policies.
 
In this project I was responsible for the following tasks:

Working with Data Sources
  The data that the program analyses is coming from different sources and in different formats. If you analyse the data over the decades, we have to bring together the data and formats stored on ancient mainframes with magnetic tapes and data from modern cloud storage. To solve this problem we had to develop and apply a variety of drivers to connect to different database types, converters formats and algorithms to convert data to a common format. 

Optimisation calculations
  Working with large data heavily overloads computers functionality. To speed up the computation the program uses multithreaded computation for the effective use of multicore processors. Also there is a mechanism for the fragmentation of tasks for the organization of cluster computing.
Billions of records exceed the capacity of the computer's memory and the permitted dimensions of arrays. To overcome these limitations, a special algorithm was created to do the cyclical refinement calculations. First, the program would perform a quick approximate calculations. Those fragments and analysis strategies that allow the most profitable results are calculated with higher accuracy. This method accelerates the results within a hundred times. The analyst can quickly assess whether the strategy gives a positive result, then the successive corrections to create a variant with maximum profit.

Presentation of results
  For clear and easy visualization of results of calculations program contains automated systems for constructing tables, charts, graphs with comments. Output and storage of analysis results is made in a universal format that can be used on different hardware platforms and operating systems. The program used a modular architecture that allows developers to quickly and flexibly add and combine different analysis options.
  The program is written in C#, has more than 50 000  lines of the original code. 

During 2010-2012 years, in National Academy of Management, Kiev, Ukraine, 
 I was the lead developer of the  
Foreign Languages Teaching and Learning Programme (http://wordplay.bestvariant.com)

   The Programme is based on fundamentally new methods of learning, built on current scientific research in the psychology of perception and memory. The programme uses the most advanced system computer analysis of the speech and pronunciation.

In this project I was responsible for the following tasks:

- Development and coordination of architecture and technical specifications
- Development of the entire code, user interface elements and design
- Testing of automated and manual
- Technical support, automated upgrade and release new versions.

Programme Technical Features:
   The programme uses a full multi-language interface by utilising of linguistic resource libraries and vocabularies. This allows the flexibility to switch between interface languages and provide translation from/to any language.  Asynchronous and multi-threaded parallel calculations are used in critical and heavily loaded programme modules to accelerate functionality and effective use of computer power.
   The programme utilises the most up to date libraries for synthesis and speech recognition. The programme features include an adjustable threshold for quality pronunciation, graphical display of pronunciation spectrum, multiple plays of freely selected audio records. 
   The WPF technology is used for the programme design. The technology allows functionality for comprehensive graphic data output and display as well as developing a multi layered information interface. 
    The programme contains 22 126 original code lines.

During 2005-2008 years, in Ministry of Internal Affairs, Kiev, Ukraine
I was the leader of a group of developers to create specialized programs against crime:

- Program analysis of conflicts of interest and to avoid corruption.

 The program analyzed police officers social and family contacts.  If the program detects a conflict of interest were appointed depth investigation.
It was revealed several hundred cases when officers investigate crimes of relatives or friends. This led to the concealing of evidence or illegal termination of the investigation.
  Also there were identified several high-ranking officials who commit dishonest procurement of equipment and materials for the police.
Tender procedure were violated in favor of the companies of close friends or relatives.

- The program for tracking organized criminal groups

   The program analyzed the cases of repeated or similar crimes committed by criminal groups. Perform statistical analysis of the use of mobile phones in the area of ​​crime. When match of phone numbers was found programme started the analysis of all contacts and locations. In this way, was able to arrest several criminal groups of kidnappers and groups of attackers on cash collectors.
    The main technical problem in the development of these programs has been collecting data from heterogeneous databases and API. Police database developed long ago and used the old versions of computer languages ​​C, Pascal, SQL and old versions of data communications protocols. Because of the different data rates from remote and heterogeneous sources program to use asynchronous multithreaded architecture.
   Group software developers has been awarded police medals for the development and high efficiency of the proposed new technologies for investigations.  I was awarded the highest medals of police - "Cross of Glory", "Knight of the law" and "Badge of Honor Organized Crime Department".
