Work ———
In my current role, I'm developing C#-based RF test automation
software for a critical NPI. These programs communicate with a DUT
using register-level socket commands to automate tests such as
S-parameters, time-domain reflectometry (TDR), and component-level
verification. Each new device under test (DUT) requires me to
first build a driver to enable basic device control. Then, I
develop methods to control attenuators, amplifiers, switches, and
other PCB-level components. I also build a control panel GUI for
each DUT to help streamline troubleshooting. The end goal is to
have a full suite of tests that a technician can reliably run at
the click of a button and the connection of a few cables.
I also started a side project to fully automate test station PC
setup. In doing this, I significantly reduced the work hours
required to configure new test stations. In turn, this helped to
build the relationship between my team and the Keysight IT team,
ensuring that we are aligned regarding PC safety and cybersecurity
in the future.

Supporting an evolving assortment of Keysight's products over the
years, I resolved over 450 post-sales issues in Jira Service Desk
& Salesforce. This involved collaborating with sales personnel,
application engineers, and customers themselves. I was the sole
USA-based point of contact for government and high-security
customers for certain products with sensitive customer
requirements.
To enable efficient repair and calibration, I delivered
in-person technical training for vector network analyzer service
and verification. Additionally, I worked to improve and expand
customer-facing programming examples to help them automate their
solutions. This included example scripts in C#, C++, Python (using
both PyVISA and IVI-COM), VB.NET, and Excel VBA. For internal
customers, I developed applications for some of Keysight's VXT
transceiver products using C#, enabling faster diagnosis of
hardware, software, and FPGA issues.
Meanwhile, I was also an active leadership member of
Keysight's largest employee networking group. On the leadership
team, we organized professional, social, and philanthropic events
for over 300 members.

After graduating from UC Davis, I joined Keysight's engineering rotation program. The quantum team was just getting started at the time, and they ended up retaining me for almost the entire duration of the program. I worked with this team as they set up an agile development system using Jira and as we developed Keysight's first few custom solutions for customers in the quantum computing space. These solutions utilized hardware and software recently brought into the company's portfolio via an acquisition as well as existing equipment. In my time with the team, I determined the scalability of our solution for systems utilizing more qubits, wrote VHDL FPGA code blocks for use in our FPGA design software, and documented the FPGA design software.

In a team of just two electrical engineers and a professor acting as our supervisor, we designed, built, and delivered a tool for training emergency first responders. The training device was made at the request of the UC Davis Veterinary Medicine Department.

While attending classes at the Santa Rosa Junior College, I worked as an intern in Micro-Vu's electronics department. During my time there, I assembled, evaluated, calibrated, and diagnosed problems with circuit boards and peripherals.

I worked as a math lab assistant in SRJC's "Math Lab", a classroom repurposed as a gathering place for students to work on their math-related homework. My job was to help the students finish their homework and understand the material, whether it was trigonometry, multivariable calculus, differential equations, or linear algebra. I enjoyed helping my fellow students get those "a-ha" moments even when they were feeling discouraged by the difficulty of the subject.

"TileVania" Platformer in Unity
This game was part of a larger course by by GameDev.tv which included the creation of five Unity games of varying types, but of those five TileVania was my favorite. This little platformer game taught me some of the biggest factors that go into making a fun 2D game. I look forward to using what I learned here in games I create on my own in the future.

AutoBudget - Excel VBA Project
I was disappointed with the popular budget tracking options
available like Mint and YNAB. Instead of creating category "bins"
to limit spending in, I just wanted a way to see where my money
was ending up, broken down in a few different ways via nice
graphs. I created this Visual Basic for Applications (VBA)-based
budget spreadsheet in Microsoft Excel which makes it easy to input
expenses, income, and reimbursements through a simple user
interface. Everything else is done automatically. I use this to
track my own finances, as do many of my peers.

BlockGraph
BlockGraph is a Unity project which uses elements of Unity's
Universal Render Pipeline (URP) and ShaderGraph system for
defining shaders. It creates fun mathematical animated shapes with
any number of blocks which are colored by the shader code, based
on their XYZ coordinates. Effort was put into optimizing the
render pipeline for minimum frame render time.

IronSpell
This is from of the Core Combat course by GameDev.tv, in which we create a RuneScape-style RPG with a click-to-move system, a rich environment, and enemies with patrols and guard duties. This course built upon the skills learned in the one mentioned in my TileVania card. Effort was put into planning out the game from the beginning and building a custom world for the characters to inhabit.

I took a 3Ds Max modeling and animation class at the SRJC and loved it. This was my final project for the class. The satellite is based on the European Space Agency's Rosetta space probe, and the interior area is based on NASA's space shuttle Atlantis. The banana is based on a banana.
