Summary
👤
Senior🎓
Top SchoolPohsun Tseng is a senior software engineer based in Germany with 7 years of experience specializing in high-performance computing, large-scale C++ systems, and computational geometry for EDA and lithography. He has a PhD in Computational Astrophysics and applies scientific rigor to engineering problems, designing scalable parallel algorithms (quadtree + graph partitioning) that scaled to 32 nodes with 71% efficiency and achieving near-12× intra-node speedups on 32 threads. At KLA he developed optimal sweep-line and interval-tree solutions for polygon overlap counting and accelerated image-processing pipelines with CUDA, resolving critical customer escalations for micrometer-scale defect detection. Comfortable across CPU multithreading (OpenMP), GPU (CUDA), and algorithmic data structures, he blends research-level modeling with production-oriented performance tuning. An often-overlooked strength is his ability to translate complex numerical methods from his PhD into robust, high-throughput engineering solutions for semiconductor tooling.
