Delivered faster, more reliable, more usable embedded software for Lumafield's X-ray CT scanners, enabling high-volume inspection usecases in factories.
• Reduced per-image processing time 30-50x to enable minute-long scans with quality equivalent to hour-long scans, replacing Scipy/Numpy/OpenCV algorithms with simpler, custom SIMD C code
• Improved scanner UI responsiveness 90% while making UI code easier to change and increasing type safety, by writing a Typescript code generator and implementing O(log(n)) instead of O(n) state updates
• Led 75% variable cost reduction project to move the 3d reconstruction pipeline from AWS servers to on-scanner CPU+GPU compute for high-volume customers
• Root-caused intermittent 300ms system stalls using full-system profiling and reverse engineering tools including NSight Systems, LD_PRELOAD, Cutter, and jemalloc
• Worked closely with QA, scanner fleet services, and frontend/backend software teams to implement, troubleshoot, and fix features for customers and internal teams
