I led firmware bring-up across 15+ MCU-based subsystems within the sequencer, establishing reliable communication and control between sensors, actuators, and fluidic components. This included defining interfaces, bringing hardware online, and debugging issues at the boundary between embedded code and higher-level system behavior. On the software side, I developed control-layer components within a Linux-based C++ environment to interface with custom MCU firmware. This required coordinating timing, data flow, and system state across multiple layers, where small mismatches could propagate into larger system issues. A significant part of the work involves verification—ensuring real-time behavior, timing accuracy, and correct sequencing of operations under complex workflows. Many issues only appear when subsystems interact, so debugging often means working backward from system-level behavior to isolate root causes across hardware and software. The work is highly cross-disciplinary, requiring close collaboration with electrical, software, and scientific teams to ensure the system operates reliably as a whole, not just at the component level.
