Summary
👤
Senior🎓
Top SchoolSergey Parshin is a systems-focused software engineer with 13 years of professional experience, specializing in C++ since 2004 and C# since 2014, currently building low-latency trading systems and HFT infrastructure at Susquehanna International Group. He excels in backend services, kernel modules, drivers, networked daemons and hardware-facing code (including FPGA integration), with practical Python use for data analysis. Previously he led cross-platform native development and performance optimization for image-processing and remote-control products, porting components to macOS, Linux, Android and even experimental platforms. Not a UI person by trade, Sergey’s strength is squeezing performance from multi-threaded systems and stabilizing complex code under real-world network and device constraints. Based in Ireland, he pairs deep systems craftsmanship with a wide hobbyist curiosity spanning Kotlin to VHDL and a hands-on approach to solving hard infrastructure problems.
