Work experience

Crossover

March 2018 - present

Product Chief Architect for Manuscript (Fogbugz) Import. As Product Architect, I was responsible for Kiln project handover from Fog Creek company to Crossover. This includes knowledge transfer and coordination of CI/CD, QA, Automation, Bug Fixing, and Unit Test teams. The goal of the import project was to set up all processes so that the product could be released every 7 days. That goal was achieved in 4 months with +80% to unit test coverage, 250 tests automated and deployments to QA and Staging environments every night.

EPAM Systems 

July 2016 - March 2018

Position: Team Leader and Senior .Net Developer

Teletrack

Teletrack is a consumer reporting agency that provides consumer reports to third parties for the purpose of credit risk assessment and/or other purposes. Legacy code and out of dated infrastructure.

Technologies: C#, Microsoft .NET, SOA Architecture, SOAP, WCF, MS SQL

I was leading a team of two developers and two QAs. My team had full ownership over the whole system which consists of public SOAP interface, around 30 web services on backed, five databases and couple of standalone apps. We were able to successfully onboard the project and deliver critical functionality in tight deadlines.

At the initial stage of the project, I was facilitating knowledge transfer and project handover from other vendor’s team to make sure that the transition process won’t affect business continuity

As a scrum master, I was responsible for establishing SCRUM process. Work with the product team and other stakeholders from the customer side on setting priorities and defining business goals for the team.

Project did not have development infrastructure. My main goal was to develop and implement a strategy for establishing a continuous integration process. I coordinated effort of developers, QA automation and two devops engineers on restoring production code base, migration source code to GIT, set up build and deployment automation, improve QA automation coverage and accessibility. We used Jenkins, Nant, Gerrit and custom QA automation framework.

Luxoft. Credit-Suisse account

September 2013 - July 2016

Position: Senior .Net Developer

CVA Desk IT (Credit Valuation Adjustment)

Technologies: C#, Microsoft .NET, MS SQL, WPF, WCF

I was responsible for the implementation and design of new functionality in Collateral Handle application that manages Credit Support Annex Documents and provides data for the downstream system. One of my main achievements was the redesign of document assignments process to make it more transparent and effective for users. In order to achieve that goal I had to refactor and cleanup codebase. About one hundred of unit-tests and integration tests were written as part of this process.  This significantly reduced the cost of changes in the system and improved quality.

Collateral Handle application based on legacy code so I spent significant efforts on refactoring of the system in order to make sure that it is able to quickly acquire new requirements with decent quality. I have written about 100 unit and integration tests.

I was working on a tool that combines data from different sources in one Excel report. I worked on performance tuning that allowed to reduce the time of report generation process from 4 hours to 10 minutes.
