Fully Parallel Queries Execution Library

I developed an SQL queries execution library in the scope of the GaneshaDB project at DCEngines.

The library is written in C++14. It parses an SQL query into an abstract syntax tree, then simultaneously executes the tree using Facebook folly futures. It deals with the Apache parquet and arrow formats, as we store the database in parquet files.

Historical and Real-time Market Data Loaders

While working at OneMarketData I designed and developed different kinds of market data loaders. I developed both, real-time and historical data loaders.

During these kinds of projects, I got familiar with the financial data formats such as Reuters, FIX, OPRA, and MarketPrizm.

Financial Market Orders Generation and Execution System

At OneMarketData I led a small team in building financial market orders generation and execution system. We named it Orders Management (OM) system.

OM is a distributed system written on C++, which can automatically handle all the steps and issues that appear in automated algo trading, including automated signal generation based on a given trading algorithm, responses handling and fault tolerance issues.

The system supports FIX and AMQP protocols to communicate with third-party exchanges and brokers.

Special Libraries for Python and R Native Environments

At OneMarketData I designed and developed two libraries that allow using company's product functionalities from Python and R shells. To develop these libraries I learned Python and R C APIs.

Third Parties Integration with Synopsys Standards

In 2012 I was hired at Synopsys to integrate Virage Logic company's third parties and build tools with Synopsys global standards. At that time Synopsys acquired Virage Logic company.

I led a team of two developers. We managed to fully complete the task in six months, however, initially it was planned to be fulfilled in nine months.
