Jongsok Choi is an engineering manager and ex-startup founder with 8+ years of experience building compiler and FPGA toolchains, currently leading work on the PyTorch Compiler Backend at Meta. He co-founded LegUp Computing, developed a patented LLVM-based HLS compiler that enabled multi-threaded C/C++ to FPGA flows, and successfully exited when Microchip acquired the company and integrated SmartHLS into its product line. At Microchip he scaled cross-functional teams and served as Toronto site director, architecting a unified system-level design environment for RISC-V SoCs and HLS IPs. His background blends deep academic research (PhD work on LegUp at University of Toronto) with hands-on hardware and compiler engineering across Intel, Qualcomm, and other firms. He’s comfortable shipping complex toolchains that bridge software and hardware, and quietly accumulates practical wins—like patentable compiler optimizations and university-community open-source impact—that drive commercial adoption.
