Who Am I?

I'm an aerospace engineering student at Cabrillo College with a focus in aeronautical engineering. I use CAD to design and visualize engineering concepts, turning ideas into precise, buildable models. Alongside technical design, I work with tools like Photoshop and After Effects to present my work clearly and professionally.

I'm driven by a passion for flight and the engineering behind it, and I'm constantly pushing to sharpen my skills across both technical and creative disciplines.

Turbine

CAD Design (1)

Turbine

For this project I modeled a fully bladed axial turbine rotor built around a central hub and nose cone. The main challenge was patterning dozens of blades from a single airfoil profile while keeping smooth, continuous transitions into the hub across the entire rotor. I focused on getting the circular pattern precise and consistent, making sure each blade maintained the same geometry and spacing without any misalignment at the root connections.

Turbine Stages

CAD Design (2)

Turbine Stages

For this project I modeled a 6-stage axial power turbine assembly based on jet engine architecture. I used an exploded view to clearly show how each turbine disc and blade ring stage relates to one another, which is a standard approach in engineering documentation for communicating assembly sequence and part hierarchy. I focused on maintaining axial symmetry, consistent inter-stage spacing, and accurate radial blade profiles throughout all six stages.

Plasmaraptor 3

CAD Design (3)

Plasmaraptor 3

This is my third iteration of a concept plasma engine I designed from scratch. Each version built on the last, refining the overall form, housing geometry, and nozzle shape. The goal wasn't to follow an existing reference, it was to take an idea and turn it into something that looked coherent and buildable in CAD. The '3' is honest. The first two versions had problems I wasn't happy with, so I kept going until the geometry made sense visually and structurally.

Pixie

CAD Design (4)

Pixie

Pixie is a small precision component I designed as part of the same plasma engine concept. Small parts are actually harder to get right because every surface and connection point has to be intentional. This was an exercise in clean, tight geometry and making sure every interface point looked like it belonged there.
