Electrical Engineer
Penn Electric Racing
- Developed the battery simulation schematic for the power distribution unit testing board in Altium and simulated with LT Spice to optimize debugging of cell voltages, I2C data signals, power switching, and current sensing
- Debugged the REVX Voltage Select using bench top electronics and designed PCBs with different MOSFET and ICs
Research Assistant
University of Pennsylvania – Radway Group
- Characterized CR2032 coin-cell battery discharge under pulsed loads to inform power-management strategies for wearable SoCs
- Built and tested a predictive model relating current draw, duty cycle, and pulse timing to usable battery capacity, enabling workload-aware energy estimates
Teaching Assistant
University of Pennsylvania – School of Engineering and Applied Sciences
- Assisted students with CAD design, IoT, and embedded systems to develop software-controlled systems based on the Arduino and Raspberry-Pi that interface with the real world
Founding Engineer
SunShutters
- Prototyped an automotive cooling system by modeling circuitry and mechanical design in Fusion360
- Iteratively developed and tested three versions of PCB boards, improving circuit optimization and reliability
- Increased system efficiency by 26% through optimized power design, battery configurations, and wiring testing
- Pitched to industry professionals, including Nexans Communications Director, regional Honda employees, and T-Mobile directors; received over $10,000 in seed funding and finalist for 5+ national STEM and Business competitions
Research Intern
NASA, The University of Texas at Austin - Center for Space Research
- Improved flood risk analysis by 83% through developing a custom Classification and Regression Tree machine learning algorithm to analyze digital elevation data
- Generated 3x more accurate flood prediction maps through modelling geospatial data in ArcGIS and implementing custom visualization techniques
Projects
A showcase of my technical work and engineering projects
Custom RISC-V Processor
Developed and optimized pipeline architecture for a RISCV CPU core using System Verilog with AXI4-Lite Interface, deployed on FPGA for testing and performance
Aura
Developed a computer vision-powered desktop application with an emotion recognition system build using OpenCV, TensorFlow, and Matplotlib to track and respond to the user's mental and physical fatigue in real-time. Trained a custom GPT focused on mental and physical well-being to interact with users via a chat interface
WordHack
