Curiosity.
Put to work.

I’m Joshua, an electrical engineering student who loves figuring out how things work—and making them work better.

I build custom electronics, write software, and help teams turn good ideas into something real.

Seeking electrical engineering internships.
Especially embedded systems, PCB design, and power.

Built from curiosity.

A closer look at the systems I’ve worked on, the problems behind them, and my part in the process.

Working on the electric vehicle’s wiring and telemetry electronics
02 / Electric Vehicle Grand Prix2022–2025

From circuit board to starting grid.

I designed and built the custom PCBs and wrote the telemetry code from the ground up, connecting vehicle electronics with data collection for our race team.

  • Raspberry Pi
  • LoRa radio
  • Telemetry
The work & the results

My contribution

I designed and built the PCBs and developed the telemetry code from the ground up. I was the lead electrician and software developer, and served as co-president in 2023–2024 and president in 2024–2025.

The Raspberry Pi system I worked on

During my involvement, the system was built around a Raspberry Pi. I designed the custom PCBs and telemetry software to bring vehicle data from the car to the pit.

The earlier code combines Arduino sensor collection with Raspberry Pi processing and LoRa radio. The 2024 season repository moves more acquisition onto the Pi, using I²C analog-to-digital converters and an inertial measurement unit. The car and pit repositories document the onboard collection and receiving software.

Team results

  • First-place qualifying lap and third overall at the international competition in Abu Dhabi, UAE, March 2024.
  • First place at the Shenandoah Valley competition, April 2024.
  • First place at the Washington, DC regional competition, June 2024.

Returning on the other side of the track

In spring 2026, I joined the EVGP officiating team. My first event as an official was in Dubai, UAE—the next chapter after competing as a student.

Making data discrepancies easier to find.

During my IT internship, I wrote SQL scripts to look for errors and inconsistencies in duplicate Snowflake databases. Simple tools for a practical data problem.

  • Snowflake
  • SQL
  • Automation
From detection to diagnosis

The problem

Duplicate databases contained inconsistent data. Finding the differences was only the first step; understanding their source mattered just as much.

My contribution

I wrote SQL checks, analyzed inconsistent data, traced errors to their sources, and submitted requests to have those sources corrected. The scripts were straightforward; their purpose was to make errors easier to find.

The experience

This work connected software development with practical investigation: using a tool to surface problems and following the evidence back to their cause.

04 / FIRST Tech Challenge2021–2024

CAD, fabrication, competition.

I designed robots in Onshape, built them with 3D printed and laser-cut parts, and helped program them for local and state FTC competitions.

  • Onshape
  • 3D printing
  • Laser cutting
Designing as a team

I served in head leadership on Harrisonburg High School’s robotics team in 2023–2024. Working in partnership with Shickel Corporation, our team brought digital designs into physical builds and iterated for competition.

Our 2023 recognitions included the Technical Innovation Award, first-place Inspire Award, and first-place Qualifying Award.

Electronics with a different destination.

I joined Virginia Tech’s Orbital Launch Vehicle Team in 2025 and worked on redesigning a custom flight computer PCB with the electronics team. I’m still a member and am currently taking a break from active work.

  • PCB design
  • Flight electronics
  • Team engineering
06 / Web & infrastructurePersonal & team work

A home for the work.

I build and host my own portfolio, work with PCs and servers, and maintain the Human Powered Submarine team’s website and internal SharePoint.

  • HTML & CSS
  • JavaScript
  • Linux
  • SharePoint
Building beyond the browser

I built my first computer at age ten. Since then, I’ve continued learning through custom PCs, hardware and software troubleshooting, server management, and the Linux command line.

For me, maintaining a site is part of the work: keeping information useful, accessible, and current for the people who need it.

From theater sound boards to game-day livestreams, I help the people on stage—and in the stands—have a better experience.

From theater to Virginia Tech

Marching Virginians

I joined as a manager in 2025, supporting the leadership team and managing livestreams of the final practice before games. In August 2026, I became Head Undergraduate Staff.

School & community theater

I was lead sound technician for Harrisonburg High School productions of Chicago, Newsies, Cats, and High School the Musical between 2021 and 2025. I also led sound for Can’t Feel at Home at Court Square Theater in 2024.

Sharing what I know

I trained Thomas Harrison Middle School students on sound equipment in 2023, supported church livestreaming from 2018–2022, and served as my high school marching band’s Electrical Logistics Leader and Lead Sound Technician in 2022–2024.

08 / Quiet ClassesAI-assisted development

Silence, on your schedule.

I built an Android app with AI-assisted coding to activate Do Not Disturb around a class schedule, with optional location checks.

Flexible class rules, a weekly calendar, and portable settings backups help make it useful beyond a single timetable.

  • Android
  • Kotlin
  • Jetpack Compose
The product & the decisions

Make the rules fit real classes

Recurring weekday schedules can work by time alone or check one of several locations. The schedule engine also handles overnight classes and overlapping rules.

Work with Android’s background behavior

The app combines class-boundary alarms, geofence transitions, and a periodic background check to evaluate when its rules should apply.

Keep the user in control

Schedules and settings stay on the device, with JSON import and export for backups. The media-volume logic checks for manual changes before restoring volume.

How I built it

This is a personal project developed with AI-assisted coding. The native Android implementation uses Kotlin and Jetpack Compose.

The knack.
And the kindness.

Growing up in Harrisonburg, Virginia, I was often told I had “the knack” for engineering. I built my first computer at ten, and I’ve been following that curiosity ever since.

Today, I’m a sophomore studying electrical engineering at Virginia Tech. I enjoy the space where hardware, software, and real-world problems meet: designing a board, tracking down an error, or making a system easier for the next person to use.

My goal is to use engineering to improve the world around me, bringing technical creativity and kindness to the work. That same motivation shows up when I’m mentoring students, helping with a performance, or doing yard work with my brothers.
