Beyond The Code

When I'm not rendering pixels, I'm chasing horizons

Private Pilot

There's a unique connection between flying and graphics programming - both require understanding complex systems, precise calculations, and a passion for seeing the world from a different perspective. As a licensed pilot, I've experienced firsthand how mathematics and physics come together to defy gravity.

Flying has taught me patience, precision, and the importance of preparation - skills that directly translate to my work in computer graphics and software development.

Skydiver

If programming teaches you to think in algorithms, skydiving teaches you to trust them. The rush of freefall at 120+ mph is unmatched - it's pure physics in motion. Every jump is a reminder that the best experiences come from stepping outside your comfort zone.

The parallels to graphics work are surprising: understanding aerodynamics is like understanding light transport, and landing safely requires the same attention to detail as debugging complex shaders.
