As the Electrical Power Subsystem Lead for SharkSat-1, I guided the design and integration of a reliable spacecraft power system in collaboration with a multidisciplinary team. I also completed a senior thesis project focused on a machine learning-based fall detection system, combining embedded design with algorithm development to solve a real-world health challenge. Outside of these capstone experiences, I’ve built DC-DC converters, designed custom gate drivers, and created simulation-driven hardware using LTSpice, MATLAB, and PCB design tools. I approach engineering with systems-level thinking and a strong focus on practical, scalable solutions. I’m currently seeking opportunities to contribute meaningfully to innovative engineering teams.
Electrical Power Subsystem Lead – SharkSat-1 (NASA CSLI CubeSat)
May 6, 2024 - Aug 30, 2024
I led the design and simulation of the power system for SharkSat-1, CSULB’s first CubeSat funded by NASA’s CSLI program. I drafted requirements, modeled Li-ion battery behavior in MATLAB, and managed cross-functional collaboration to pass PDR and prepare for CDR.
Power Systems Engineer – Senior Design Project
Jan 2025 – May 2025
I designed a boost converter and ±15V linear regulator system for analog circuits. I simulated ripple and grounding in LTSpice, laid out the board in Altium, and fixed a hardware issue in the LM337 section with a last-minute redesign.
Embedded Power Engineer – UPS Inverter Project
Aug 2024 – Dec 2024
I built a DC/AC inverter using an H-bridge and SPWM at 50 kHz. I ran LTSpice simulations, iterated through three PCB spins in Altium, and validated 120V AC output under load.
