Core Competencies

Professional Experience

LEXIS NEXIS – Bellevue, Washington January 2011–Present

Senior Development Lead

Architected and lead design and implementation for the new highly scalable data processing framework codename Overdrive. New framework allowed to achieve very high throughput processing legal documents and at the same time provided reliability and fault tolerance required. Overdrive was successfully retrofitted into existing ASP.NET based application and improved its backend performance by several orders of magnitude. Framework features replaceable message delivery engine, which can be MSMQ, SQL Server Service Broker or something else.

Lead design and implementation of data interoperability layer between classic Concordance e-discovery management software (C/C++, MFC, Windows API, proprietary database format) and soon-to-be-released Concordance Evolution product, based on ASP.NET, WCF, SQL Server. Wrapped very large portions of old unmanaged code with simple and consistent data translating facades easily usable by pure .NET developers on the team. Wrappers provide data access security, thread safety, 64-bit compatibility and other benefits missing in the original code.

INTELLIGENT EFFECTS – Bellevue, Washington September 2010–December 2010

Senior Software Development Engineer

Was invited to Microsoft internal software piracy tracking project as an external expert in .NET Entity Framework. Within a few weeks was able to debug, profile, refactor and optimize the client (Silverlight) and server (Entity Framework) code to speed up query execution roughly 100 times and reduce the system response time in field tests from minutes to a fraction of a second.

Designed and implemented custom WCF web service hosted in Sharepoint 2010 used to generate Microsoft Office documents (Word and PowerPoint) from provided document template and data coming from front end WPF application. Document generation engine employs OpenXML and is capable of producing documents containing rich text, pictures, dynamically formatted tables, different types of charts and videos (in PowerPoint).

ADVAIYA INC. – Kirkland, Washington August 2009–September 2010

Senior Software Development Engineer

Designed the architecture and lead implementation of several highly visible independent desktop and Internet projects leveraging Silverlight, WPF and WCF technologies. The projects required a high level of technical expertise, solid decision making and the ability to find creative solutions for the problems faced by the development team at the junction of different technologies.Designed and implemented custom Project Template for Visual Studio 2010 enabling developers to deploy their VSTO (Visual Studio Tools for Office) solutions to Sharepoint servers. Out-of-the-box VSTO supports only ClickOnce deployment; deep knowledge of VSTO and Visual Studio internals allowed Sharepoint servers to be enabled as the distribution point.Led design and implementation of a custom media player for Microsoft TechNet content. Player was implemented in both Internet (Silverlight) and desktop (WPF) flavors and is available for download from Microsoft.com.Produced several Silverlight controls for Sharepoint 2010 pages on Microsoft.com (http://sharepoint.microsoft.com) Those controls were designed to fetch all the content and configuration from the server using Web Services and can be dynamically updated without recompilation or redeployment.Designed and implemented Sales Playbook distributed application to help Microsoft sales team better explain connections between different Microsoft products and create bundle offers optimal for each client. Application uses Silverlight for UI, SQL Server as a backend and Microsoft Entity Framework and Sync Framework as a middle tier allowing online and offline work.

Software Development Engineer in Test (1999–2005)

Championed architecture, design, and development of test frameworks, testing tools, and test cases to maximize product quality for all assigned areas of the .NET Framework, including interoperability with unmanaged code and COM and hosting Common Language Runtime (CLR) inside other software applications with 64-bit portability. Coded and debugged more than 50K lines of C#, C++ and managed C++ code in tests and testing infrastructure. Composed a universal testing host with multiple plug-ins to control several parts of hosting API; tested all combinations and conducted fault injections to maximize accuracy and efficiency.Conceptualized the Bug Patrol data mining application to speed up analysis of build verification test passes from a week to less than 1 day; enabled test to run more often and issue resolution to occur much faster.Pioneered excellent quality assurance for .NET Framework integration with SQL Server, with zero major issues since its release in 2005.Produced semiautomated triage and routing of issues within QA code to the appropriate team member; mentored new team members on proper techniques and company policies.
