I am an electrical and hardware engineer in San Diego with 5+ years across R&D
hardware and regulated manufacturing, taking embedded electronic products from
prototype to production. At E-Seek I bring up and debug PCBAs, validate systems with
RF, analog, digital and power measurements, and led ISO 10373 certification of the
M600 scanner by redesigning its RF module for Cetecom BSI testing.
I build the tooling that makes testing repeatable: MATLAB workflows that capture
instrument data, compare builds and generate reports, so failures that cross the
hardware, firmware and software boundary get isolated quickly. I am completing an
M.S. in Electrical Engineering at San Diego State University (expected May 2028) and
moving deeper into PCBA and hardware design.
Experience
R&D Hardware Engineer
E-Seek, Inc. · San Diego, CA · Apr 2022 – Present
Led ISO 10373 certification of the M600 scanner by redesigning its RF module so the product could pass Cetecom BSI certification testing.
Plan and run electrical, functional, regression, reliability, environmental and design-verification tests on embedded scanner systems: PCB assemblies, power circuitry, CMOS imaging, LED illumination, firmware and communications interfaces.
Bring up, characterize and rework PCBAs using schematics, oscilloscopes, logic analyzers, spectrum analyzers, VNAs and signal generators, with controlled experiments to confirm each fix.
Built MATLAB workflows that automate instrument data capture, analysis, regression comparison and reporting.
Root-cause failures spanning analog, digital, RF, power, signal integrity, sensors, imaging, optics and hardware-software interactions.
Write test plans, procedures, acceptance criteria, fixtures and defect reports, and recommend corrective actions to electrical, firmware, software, mechanical, quality and manufacturing teams.
Production Lead
Cue Health · San Diego, CA · Nov 2020 – Apr 2022
Led daily production of regulated diagnostic products and PCB assemblies, enforcing controlled procedures, traceability, inspection requirements and safety.
Supported automated-equipment troubleshooting, defect review, escalation and corrective action to keep a high-volume line running.

Projects
Dual Power Generation: Wind and Solar (Senior Design)
Team of 11 (EE 496A/B, San Diego State, advised by Dr. Chris Mi) that built a hybrid renewable generator: a vertical-axis wind turbine with a solar panel on top, feeding a battery through AC-DC, DC-DC buck/boost and DC-AC conversion stages. I led the software group building the maximum power tracker (Raspberry Pi with an IR tachometer on the rotor, logging to a database), designed the DC-DC and DC-AC converters, and built the solar panel's sun-tracking maneuvering system (stepper motor, linear actuator and photoresistors).

Ultra-Fast EV Charging System (350 kW)
Built a MATLAB/Simulink model of a 350 kW DC fast charger: grid, active-front-end rectifier, buck-boost DC-DC stage and a 100 kWh battery with a lumped thermal model. Implemented a CC-CP-CV charging controller and compared liquid, refrigerant and phase-change-material cooling, plus an economic feasibility analysis.
Designed, laid out and simulated a 2-input XOR in three logic families (TSMC 0.3 µm, 3.3 V, 50 fF load, DRC and LVS clean) and extracted area, power and delay. Pass-transistor logic was smallest (176 µm²) and lowest power (0.005 mW); pseudo-NMOS was fastest (4.48 ns) but drew 0.337 mW from its always-on pull-up. Repeated the comparison on a 4-bit parity checker. Team project.
Static CMOS Gates and Voltage-Temperature Variation
Sized and laid out NAND (80 µm²) and NOR (73 µm²) gates matched to a reference inverter, then measured propagation delay across 0, 27 and 65 °C and 90%, 100% and 110% of VDD. Also optimized a chain of inverters for minimum delay. Team project.
Extracted threshold voltage (NMOS 408 mV, PMOS 300 mV) and transconductance parameters from simulated I-V curves, measured the body-bias effect at Vbs = ±0.5 V, and sized a CMOS inverter (PMOS 1.35 µm, NMOS 450 nm) to center the switching threshold near VDD/2. Our team was awarded extra credit for achieving the fastest propagation delay.
Imported a manufacturer SPICE model for the BAV70LT1G diode into LTspice, compared simulated and datasheet forward voltage, and checked half-wave and full-wave rectifier hand calculations (done in MATLAB) against simulation. Added filter capacitors to hold output ripple under the 100 mV requirement (about 81 mV half-wave, 74 mV full-wave). Team project.
Inverting Amplifiers: Op-Amp, MOSFET and BJT (EE330)
Designed three inverting amplifiers from one spec (18 V supply, gain of -65 or better, 30 mV / 10 kHz input, 20 kΩ load) using an AD824 op-amp, a Si7336ADP common-source MOSFET and a 2N2222A common-emitter BJT. Extracted device parameters from DC sweeps (NMOS Vtn 2.16 V, gm 5.1 mS; BJT α 0.995, β 199), tuned bias networks for low THD and low supply current, and built a Digi-Key parts and cost table.
