- Designing and building 70+ radiosonde sensor arrays utilizing Arduino Nanos; modifying sensor configurations and updating code for 915 MHz radio transmission.- Leading field deployment of radiosonde via weather balloons to capture atmospheric data – especially during lake-effect snowstorms. Managing multiple daily launches and operating ground stations to receive real-time data and monitor transmission quality.

- Designing electrical systems for a lunar rover using SolidWorks; specified motors and wiring for efficient operation.

- Designed a creative embedded systems project by transforming a steering wheel into a musical instrument, utilizing Bluetooth Arduinos and piezoelectric sensors to control audio outputs.

- Collaborated with a team of seven to generate twenty-two designs based upon prior research and internally-conducted test data to ideate solutions; ultimately down selecting to two final designs.- Conducted detailed trade studies, Test Readiness Reviews (TRR), Critical Design Reviews (CDR), and Preliminary Design Reviews (PDR) to ensure the final prototype exceeded customer requirements.- Maintained critical communication channels via Slack, email, Zoom, and in-person meetings… Show more - Collaborated with a team of seven to generate twenty-two designs based upon prior research and internally-conducted test data to ideate solutions; ultimately down selecting to two final designs.- Conducted detailed trade studies, Test Readiness Reviews (TRR), Critical Design Reviews (CDR), and Preliminary Design Reviews (PDR) to ensure the final prototype exceeded customer requirements.- Maintained critical communication channels via Slack, email, Zoom, and in-person meetings for project alignment.
