Hardware/Software Engineer @ Zoox
Jan 2022 – Present | Foster City, CA
  • Led development of vehicle network emulator platform (NST), integrating hardware, firmware, and software to simulate and validate critical network traffic patterns. Drove adoption across multiple teams for testing and validation.
  • Engineered data analysis pipeline processing 100GB+ of vehicle network data every 2 weeks; created company-wide 'StreamDB' standard now serving as source of truth for vehicle network flows at Zoox. StreamDB is used in the ethernet architecture, product security, and bandwidth testing.
  • Designed and implemented comprehensive time synchronization test framework; modified linuxptp (ptp4l/phc2sys) for enhanced control and filtering of noisy correction data. Created testbench to characterize clock drift across vehicle systems.
  • Resolved critical vehicle bringup blocker by debugging ethernet link failures to telecommunications unit; identified root cause in PHY polarity swap detection, enabling reliable high-speed communication.
  • Developed 4-layer automotive ethernet test board matching BaseT impedance standards; enabled systematic fault injection testing that uncovered critical network resilience issues.
  • Maintain and enhance manufacturing line validation suite for telecommunications and time synchronization systems, ensuring production quality and reliability.
Undergraduate Researcher @ Bio-Robotics Lab
Aug 2022 – Sep 2023 | Atlanta, GA
  • Developed FPGA-based hardware accelerators for Homomorphic Encryption on a Xilinx Zynq ZC702, focusing on key generation, encryption, and large integer arithmetic. Created a novel key-switching scheme for faster homomorphic operations.
  • Designed and optimized Verilog modules, including an implementation of the Miller-Rabin primality test, pseudorandom number generators based on LFSRs, and efficient modular exponentiators.
  • Interfaced FPGA fabric with Zynq PS using AXI IP cores and C code. Integrated ADC modules to process real-world sensor data securely.
  • Extensively debugged and validated designs using Xilinx Vivado's Simulation Suite and Integrated Logic Analyzer (ILA) on both simulated and real hardware.
Student Assistant @ STEM@GTRI
June 2021 – July 2021 | Atlanta, GA
  • Mentored 10 Students in the development of an autonomous robotic arm with computer vision and high level control.
  • Started from basic Python lessons, and got all the way to control using DH-parameters, Finite State Machines, and Computer Vision.
  • Wrote 25+ example scripts and 15+ lessons to help facilitate student understanding of various topics.
  • Wrote a ROS package to integrate computer vision, inverse kinematics, and control into a simple template stack for the students.
R&D Engineering Intern @ nth Solutions LLC
Feb 2018 – Aug 2019 | Exton, PA
  • 3D Modeled and printed parts for a variety of applications, including product enclosures, accessories, and test rigs. Designed and maintained 25+ 3D printed models, each with 10+ iterations.
  • Wrote documentation and drew diagrams for patents. Experienced with technical writing and research.
  • Programmed and range tested ESP8266 and LoRa modules to add IoT functionality to a pre-existing product.
