Twelve things I built.

Competition hardware, production software, and one paid contract engagement. Filter by discipline.

CO₂-Powered Dragster

Jul 2025
6th, TSA Nationals

Competition dragster designed in Inventor, drag-optimized by CFD, and CNC-milled from balsa. Every surface had to be reachable by a 2-axis mill, forcing real trade-offs between the ideal aerodynamic shape and the repeatably manufacturable one.

PathFinder

Jul 2025
Deployed

Slack assistant that turns diagrams into screen-reader-friendly text for blind and low-vision teammates. Reads four sources, images/PDFs via Gemini vision, the Figma REST API, the Lucid MCP server, and Visio .vsdx files parsed straight from their own XML. Multi-workspace OAuth, running under systemd on Oracle Cloud.

Long-Range Fixed-Wing UAV

May 2025
Aerospace

Self-built 3 ft fixed-wing aircraft on an ExpressLRS link. CG set by physically relocating components rather than trusting CAD; wing sized by trading loading against aspect ratio; range came from link-budget choices, not raw transmitter power. Framed in defense applications as a UAV payload-delivery platform.

Lyvboard, 3D Simulation

2026, Present
Paid Contract

Contractor engagement under a formal SOW to audit and extend a production 3D football play-simulation engine. Built the handoff and pitch ball-flight system, the full stadium environment, team-branding and logo pipelines, three camera modes, and a pre-snap staging sequence.

BOLT Dash Mount

Sep 2025, Present
Student Design Team

Custom dash mount for Virginia Tech's BOLT electric dirt bike, taken through a full design cycle. Worked backward from fixed frame mounting points and a hard clearance envelope; FEA gated fabrication so an under-strength geometry failed on the computer, not in a ride test.

HomeBase

2026
Deployed

Discord bot for running a shared household, expenses, chores, groceries, maintenance scheduling. Tracks pairwise net debt rather than group allocation, so settling up is always a direct person-to-person number. Shipped with its own privacy policy and license.

8-Gram Free-Flight Aircraft

2025
Aeromodeling

Rubber-motor free-flight model with Mylar-covered wings and simplex-curve airfoils. No electronics and no way to correct anything after launch, so all trim and stability work had to be finished on the ground, against a torque curve that decays through the entire flight.

Breakout Research Platform

2026
Quantitative

Stock-market research and paper-trading system identifying high-probability breakout candidates. Cup & Handle and VCP pattern recognition feeding an ML ranking layer, with market-regime detection, backtesting, and portfolio management. Every threshold lives in one YAML file.

Recycled PET Tensile Research

AP Research
Materials Science

Capstone measuring the tensile strength of 3D-printer filament made from post-consumer PET bottles. The contribution was rigorous measurement, not the build, controlling bottle source, color, draw speed and sample geometry, then defending the methodology live.

Drone Visual Positioning

2026
Computer Vision

GPS-denied position estimation from camera input, feeding an ArduPilot flight controller over MAVLink. Built the failure-detection layer first, as a hard prerequisite, a flight controller must never accept a bad fix, so every estimate is gated before it reaches the vehicle.

Roundabout Generator

2026
Civil / GIS

Draw an eminent-domain parcel and the app generates a geometrically correct roundabout inside it over real satellite imagery. Radius derives from road width, caps against the parcel boundary, and markings follow the curved centerline rather than radial placement.

Second Brain

2026, Present
Daily Driver

Knowledge system where an LLM agent does the bookkeeping, ingesting sources, writing and cross-linking pages, flagging contradictions between old and new claims, and keeping an append-only operations log against a strict documented schema.

Where I've worked.

Sep 2025, Present
Student Design Team Member

BOLT, Virginia Tech

Design team building an electric dirt bike. Own components through the full cycle, SolidWorks modeling, FEA validation, 3D-printed fabrication, and physical testing against the vehicle's real packaging constraints.

2026, Present
Software Contractor

Lyvboard

Contract engagement under a formal SOW to audit and extend a production 3D play-simulation engine. Delivered ball-flight physics, environment and team-branding systems, and camera modes, plus an asset-licensing risk surfaced ahead of delivery rather than after.

Jun 2024, Jul 2024
Summer Intern

Anton Paar, Ashland, VA

Operated a TAG 500 flashpoint analyzer running standardized laboratory testing on consumer-grade alcoholic beverages. Procedure-driven precision-instrumentation work where deviations invalidate results.

Mar 2025, Present
Soccer Referee

SRS-VA, Richmond, VA

Officiate competitive youth and club matches. Fast, consistent decisions under pressure with no option to defer.
