04 — Beyond code

I like challenges that push my comfort zone.

Whether that's solo backpacking somewhere new or going deep on an unfamiliar system. Also: an unreasonable amount of cheese.

Solo backpacking

Somewhere new, a backpack and a loose plan. It's where backpackr.ai came from.

Photography

Before software, I freelanced as a photographer, videographer and audio engineer.

Engineers Without Borders

Aquaponics for food resilience in Falease'ela, Samoa, and four years running STEM workshops in remote and low-income schools.

Covida FC100
