Top SchoolEkaterina Sokolova is a Principal Software Engineer based in Prague with nearly a decade of experience architecting high-performance distributed systems and storage infrastructure for enterprises like Pure Storage, Microsoft, and Deutsche Bank. She combines deep systems-level expertise in C/C++, .NET, and Linux/Windows internals with a strong track record of reducing latency (notably cutting trading-system latencies by 60%) and optimizing file storage serving 500+ customers. At Pure Storage she leads core file server design (SMB/NFS, file locking) and CI/CD/test automation, and at Microsoft contributed to the .NET runtime and YARP reverse proxy—improving networking, WebSocket/TLS robustness and proxy correctness. Her background in applied mathematics and low-level algorithm optimization informs a pragmatic, measurement-driven approach to complex protocol and infrastructure problems. Colleagues rely on her ability to turn obscure protocol edge cases into production-grade, well-tested solutions.
