I design it, then I build and test it.

Mechanical engineer working across field engineering, aerospace optimization, CFD, and hands-on builds I teach myself from scratch. This is where the work lives.

About

I'm RJ, a mechanical engineering student at the University of Georgia, graduating December 2026. I'm drawn to problems that don't stop at the CAD screen, where you have to model it, analyze it, then make it actually work in the real world.

My range runs from field engineering on a utility grid-hardening program and aerospace optimization on a Lockheed Martin-sponsored capstone, to co-founding a tour business with my mom in the Virgin Islands. When a build needs a skill I don't have yet, I teach it to myself. I learned soldering, power electronics, and embedded firmware on my own to build a walking robot in five days.

What ties it together is the full loop of design, build, and test, and communicating the work clearly enough that anyone in the room understands it.

Projects

★ Viewer's Choice 2026 The Lockheed Martin wing optimization capstone team.

Aircraft Wing Design & Optimization

Lockheed Martin · XQ-58A Valkyrie UAV · Aug 2025 to May 2026

A multi-fidelity workflow that redesigns a UAV wing for less drag at the same lift, built with OpenVSP, AVL, Python (AeroSandbox), and Ansys Fluent. CFD-validated at L/D 21.9, and it won Viewer's Choice at the UGA Capstone Design Showcase. Includes the real optimized airfoils, planform, poster, and code.

Self-taught · 5-day build RJ's 12-servo quadruped robot standing on its 3D-printed legs.

Autonomous Quadruped Robot

3D printing · soldering · power electronics · Sept 2026

I had never soldered before this build. I taught myself, printed the whole frame on my own printer, hand-soldered a 2x 18650 battery system through a buck converter to a 5V servo rail, calibrated 12 servos, and flashed the gait firmware. Five days from parts to a robot standing on its own legs.

Wind tunnel + CFD The four 3D-printed wind tunnel test shapes.

Wind Tunnel Drag Study

Experimental aerodynamics + Ansys · Aug 2025 to Dec 2025

Built a small wind tunnel and measured drag on four shapes at two speeds, then rebuilt every run in Ansys Fluent. The streamlined airfoil beat the flat plate by more than 30x, the hands-on version of what the Lockheed capstone optimized for.

School · 3D printing + FEA Four 3D-printed medical scaffold geometries.

3D-Printed Medical Scaffolds

Biomedical fabrication + Ansys FEA · UGA team project

Designed, printed, and simulated porous scaffolds for jaw reconstruction, balancing high porosity for tissue growth against surviving real bite loads. I led the fabrication and material studies; FEA showed a very stiff lattice with stress concentrating at the strut junctions.

Personal · ongoing A 3D-printed calibration boat.

Self-Taught 3D Printing & Fabrication

Creality K2 · PETG / PLA · calibration to load-bearing parts

I taught myself the full fabrication loop on my own printer, from calibration prints to the load-bearing frame of a walking robot, and the principles (thermal control, cooling, tolerances, orientation) that turn a CAD model into a part that performs.
