Top SchoolAfshin Zafari is a seasoned software developer and Principal Member of Technical Staff at Oracle with 11 years of professional experience and a PhD in Scientific Computing from Uppsala University. He has deep systems and back-end expertise, contributing to OpenJDK JVM internals and improving memory management and robustness in a high-profile open-source project. His background spans high-performance computing frameworks (achieving ~80% of theoretical peak on clusters), GPU-accelerated and multithreaded med-tech applications, and large-scale banking systems, reflecting strong C/C++ and C# skills. Comfortable leading teams and building development organizations from scratch, he blends academic rigor with production engineering and a pragmatic focus on code quality and reliability.
