I have added low-latency integration to traditional and cryptocurrency exchanges. Those include market data feeds as well as order entry interfaces using a mixture of protocols (HTTP, FIX, custom binary protocols etc.).

I’ve worked on improving and optimising HRT’s internal libraries. For example by devising a more robust time-zone API, pushing more use of new C++ features such as string_views and speeding up some operations through use of SIMD instructions.

I’ve been responsible for ongoing maintenance and live troubleshooting during trading hours. My previous experiences have allowed me to promote a better ops practices which have improved robustness of HRT’s systems.

Technologies: C++
