Undergraduate research assistant — EMPE Lab

Altium design and Code Composer Studio bring-up for the ECEN 442 DSP motor-control teaching bench, which serves 70+ students a semester. LCR characterization on an EV stator and a Nissan EESM, plus a drive-module teardown. Sampling FEM flux maps in Python and MATLAB and comparing surrogate models against them.

Electrical engineer — TAMU SOMTECH

MIRAGE, University Rover Challenge. Designed the arm’s third joint — a non-invasive clamp that holds 5 kg at 1 m reach under 50 N·m — and led a 48 W slip-ring bench at roughly half the cost of COTS.

B.S. Electrical Engineering — Texas A&M

GPA 3.923. Aggie Robotics, TURTLE, SOMTECH URC, Aggies Create.

3-phase SiC inverter stage

Switching-stage PCB and a separate isolated gate-drive board. Compact high-current loops, SolidWorks heatsink, ESP32-S3 placement, Altium Power Analyzer. Personal 48 V GaN inverter work continues from here.

TAMUhack OR lighting arm

Overhead surgical light steered by fingertip tracking. I built the 24 V power architecture for three DM556 stepper drivers — 3.3 V, 5 V, 6.8 V and 12 V rails — and did the integration. Vision and kinematics by Apoorv Agrawal, Sean Aiuvalasit and Molly Gray.

Hardware test engineer intern — SVTronics

Two summers in Plano (Jun–Aug 2024, Jun–Aug 2025). Production-tested 1,000+ PCBAs with scopes, loads, JTAG and function generators, recovering 95% of failed boards, and brought up 30+ TI evaluation boards from schematics and datasheets.

Hardware test engineer — Aggies Create

STM32 PCB validation; I2C and SPI bring-up between sensor ICs and MCU.

Combat robotics electrical engineer — Aggie Robotics

Captured SPI traffic to track down a failing nRF24L01 link and replaced it with ESP-NOW. LT8609S buck converters in LTSpice, custom KiCad boards.

CNTR electrical lead — TURTLE Robotics

Power budget and LiFePO4 integration for a VR-controlled modular humanoid, plus ESP32 arm firmware. Prototype shown to 200+ attendees.

Build team — FTC 14524

CAD, FDM prints, servo repair. Mentored Sep–Nov 2025.
