Experience
Embedded Software Intern (CPT), Erie Canal Software
–
Syracuse, NY
- Wrote C firmware for an ARM Cortex-M4 vibration sensor that cut wake-to-sample time from 180 to 95 milliseconds and extended estimated battery life by about four months.
- Added unit tests with a hardware-in-the-loop rig that caught two regressions before release; coverage on the sensor module went from 0 to 70 percent.
- Presented the work at the company's engineering demo day and received a return-offer conversation for a full-time role.
Graduate Research Assistant, Embedded Systems Lab, Onondaga Lake Institute of Technology
– Present
Syracuse, NY
- Implemented a low-power scheduling algorithm on a RISC-V development board and measured a 22 percent energy reduction against the baseline scheduler across six benchmarks.
- Maintain the lab's continuous integration pipeline for firmware builds, used by seven graduate students.
- Co-authored a workshop paper on the scheduler, accepted for a fall 2026 embedded systems workshop.
Peer Advisor, International Student Office, Onondaga Lake Institute of Technology
