Berke Y is a performance-minded software engineer with seven years of experience building low-latency trading systems, real-time data pipelines, and optimized image-processing code in Modern C++, C, and Python. He has shipped production trading engines, matching and order management components, and colocated market-data platforms while also integrating monitoring and database tooling like Grafana and QuestDB. An active open-source contributor to OpenCV, he improved PNG/JPEG codecs and enabled SIMD-accelerated libjpeg-turbo builds, yielding substantial real-world performance gains. Comfortable across full-stack and platform roles, he has implemented HFT strategies, CI/CD pipelines, and GUI tools, and he routinely mentors engineers to accelerate delivery. Based in Arona, Piedmont (Turkey), he combines systems-level optimization with practical automation to squeeze latency and resource use out of complex production environments.
