Built a Python log navigator using Linux syscalls and Redis that saved operators ~30 min/day navigating Data Acquisition and Plasma Control logs. Added two new experiment metrics in Python that check thresholds on each fusion shot and alarm operators when crossed. Also built a C++ Qt GUI app for operators to control a reactor component that previously had no dedicated interface.
