1. Supporting Patching service for Fusion App. A tech stack is Java.

2. Worked on the "Pixel Server", a low-latency, high availability, real-time data delivery system built on Lighttpd/Apache module in C/C++ that enables marketers with intelligent information to target users with more relevant ads. Served over 10 Billion requests/day and transferred ~10 Trillion data stamps/mo.

3. Worked on project ADI. Uses Golang, python, C++, STL, Kafka, Docker, Kubernetes, Aerospike. Responsible for development, design, code review.

Worked on project Drake to mask candidates real phone numbers from recruiters using a proxy phone provider (Twilio).

Contractor at Goldman Sachs.

Key member of the SKYSYM software engineer group. The client is SouthWest Airlines. Responsible for software development of Application UI, Animation, Backend and service layer. This project has tight time limits and for deliver to client worked on extreme pressure. Used C#, WPF, XAML, MSSQL, Multithreading, Synchronization in this project.

• Have done research on Animation how to show and optimize performance of many moving primitive (like plane) objects on the map with effective use of memory with using multithreading with synchronization.

• Service layer development which is based on REST protocol.

• Backend development which is based on multilayer structure.

• UI controls development.

• UI development with using C#, XAML, WPF, MVVM pattern, Telerik library.

• Have done numerous memory analysis of application for finding weak places using memory tools in 32 and 64 bit windows platforms.

Key member of the Henry S3 - Network Simulation System software engineer group. The client is BHPB. Responsible for software architecture/development of Track editing tool and Animation. Used C#, Silverlight, MSSQL, ESRI library, lot of math and algorithms in this project.

• This simulation system is to help BHPBillton determine major capital investments running in hundreds of millions of dollars in the coming years in new hardware and software technologies to increase its rail network capacity.

• Designed and implemented Track editing tool which allows do multiply manipulations with rail track. Used lot of math, algebra and various algorithms in development of this tool.

• Have done research on Animation how to draw and optimize performance of many moving polyline (like trains) objects on the map with zoom support.

• Service layer development which is based on WCF SOAP protocol.

Credence company was buyed by LTX and both companies had their own ATE devices, when I was hired. The unique platform was created for both ATE devices and our group was responsible for porting Credence instruments software to new platform. The difficulty was that there were many gigabytes of old source code which should have been done refactored. Some code were written by hardware engineers long time ago with C style. I refactored code to modern C++ with using design patterns, STL library.

• Refactored old code (used C/C++, STL, boost library in Centos Linux)

• Implemented various drivers for ATE devices (used C/C++, STL in Linux)

• Implemented internal utilities (used C/C++, STL in Linux)

• Fix various issues. ( used debugger like TotalView)
