Experience
Fully Parallel Queries Execution Library
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
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
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
Third Parties Integration with Synopsys Standards
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.
