CYBERTRUCK
Cybertruck is built with an exterior shell made for ultimate durability and passenger protection. Starting with a nearly impenetrable exoskeleton,
every component is designed for superior strength and endurance, from Ultra-Hard 30X Cold-Rolled stainless-steel structural skin to Tesla armor glass. Now entering
a new class of strength, speed and versatility—only possible with an all-electric design. The powerful drivetrain and low center of gravity provides extraordinary
traction control and torque—enabling acceleration from 0-60 mph in as little as 2.9 seconds and up to 500 miles of range.
S3XY
Tesla Inc (Tesla) is an automotive and energy company. It designs, develops, manufactures, sells, and leases electric vehicles and energy generation
and storage systems. The company produces and sells the Model Y, Model 3, Model X, Model S, Cybertruck, Tesla Semi, and Tesla Roadster vehicles.
At Rivian I got to work on the 2022 R1T, R1S, and Amazon EDV. As a design release engineering intern, I had the oppurtunity
to work on both system validation and component validation on the R1 program. The components I spent the most attention on
were the wireless charging pad within the vehicle and the intrusion detection module. The intrusion detection module uses
ultrasonic waves to detect break-ins and works seamlessly with the car's Gear Guard protection system in order to alert
the owner of the vehicle. I worked with international suppliers in order to calibrate and integrate the intrusion modules
into the vehicle and test for false-positives and false-negatives with the system. The wireless charging pad is a multicoil design,
meant to charge a multiple devices on a flat surface. Due to the emergence of MagSafe technology from Apple, multicoil designs have become obselete.
The wireless charging pad is a multicoil design, meant to charge a multiple devices on a flat surface. Due to the emergence of
MagSafe technology from Apple, multicoil designs have become obselete. The magnets utilized in the MagSafe design disrupt the magnetic field
of the wireless charger and initiates a current protection state for the wireless charger. This phenomenon is known as foreign object detection
and is desired. However, the newer iPhones will force the charger into the state even though a foreign object is not present. In an effort to solve this
issue, multiple solutions were proposed and validated including: changing the coil layout, introducing dividers for the charger, and increasing the friction
between the phone and the pad.

PSYCHE
The Psyche mission is a journey to a unique metal-rich asteroid orbiting the Sun between Mars and Jupiter.
What makes the asteroid Psyche unique is that it appears to be the exposed nickel-iron core of an early planet, one
of the building blocks of our solar system. Deep within rocky, terrestrial planets - including Earth - scientists
infer the presence of metallic cores, but these lie unreachably far below the planets' rocky mantles and crusts.
Because we cannot see or measure Earth's core directly, Psyche offers a unique window into the violent history of
collisions and accretion that created terrestrial planets. The mission is led by Arizona State University. NASA's
Jet Propulsion Laboratory is responsible for mission management, operations and navigation. The spacecraft's
solar-electric propulsion chassis will be built by Maxar (formerly SSL) with a payload that includes an imager,
magnetometer, and a gamma-ray spectrometer.
EUROPA CLIPPER
NASA's Europa Clipper will conduct detailed reconnaissance of Jupiter's moon Europa and investigate
whether the icy moon could harbor conditions suitable for life. The mission will place a spacecraft in orbit
around Jupiter in order to perform a detailed investigation of Europa -- a world that shows strong evidence
for an ocean of liquid water beneath its icy crust and which could host conditions favorable for life. The
mission will send a highly capable, radiation-tolerant spacecraft into a long, looping orbit around Jupiter
to perform repeated close flybys of the icy moon.
WE BUILD THE IMPOSSIBLE.

AMP MISSION
The Advanced Mission Program consists of proprietary ground data-centers and a constellation of classified satellites. At this stage in the program, the spacecraft
and ground control systems have not yet been built and were still in the software simulation stages. I developed training scenarios that allowed test engineers to train
mission control operators on faults that may occur in the system. I drafted the system-level requirements for validation of datapath flow and communications between mission
management and the various simulations. Utilizing Python and the Robot Framework, I developed an automated test script that allowed the software engineers to validate their
simulator's functions.
he priority of this project was to emulate FPGA bitfile loading into the simulator. Each FPGA had to be activated and deactivated individually in order
to ensure that no data is lost. Additionally, if a spacecraft were to be damaged or lose communications, the ground control system must be able to autonomously communicate with
the other satellites active in the constellation. In order to accomplish this, the ground control stations must conrol their slew angle and direct themselves
to an available spacecraft immediately. During this process, multiple parameters were collected and validated including: power usage, slew rate, and data throughput.

TEST ENGINEERING INTERN
PRECISION STRIKE
My internship at L3 IEC consisted of circuit testing on navigational equipment including GPS and guidance systems. Additionally, I learned about the fundamentals
of digital signal processing and taught an ECE-101 to my fellow interns. Most importantly, I redesigned the employee auditing system. Before, the government project
timesheets were filled out and logged by hand. I utilized Microsoft Excel and VBA in order to automate the process and reduce the amount of time needed to calculate
said hours. This script also determined the amount of time spent within each building of the facility, and led to more accountability within the workplace regarding
secure compartmentalized information.
