HELLO! MARK HERE
I’m a Hawaii-based creative freelancer with 15+ years of experience in branding, user experience, and product design.
When not creating, I’m out documenting, dog-walking, and wrestling pebbles.

THIS MIGHT BE A BIT TMI BUT
I Care Too Much About What Others Think
I’m a Hawaii-based Brand & UX Designer and Design Engineer, currently moonlighting as a creative lead at a remote consulting firm. My background in small, tight-knit agencies has turned me into a Swiss Army knife of design—flexible, adaptable, and always ready to tackle whatever comes my way.
Over the years, I’ve worn many hats (and occasionally a party crown): motion graphics artist, web developer, project manager, art director, photographer, flight attendant (for client hand-holding), party host, and bartender (okay, that one was mostly for team morale). Since kicking off my career in 2007, I’ve been deep in the world of branding and product design, blending creativity with strategy to craft experiences that don’t just look good, they feel right.
These days I also work as a design engineer. I take a brand from strategy through UX and straight into working code, prototyping and shipping with AI-assisted tools like Claude Code and Figma Make. One person, the whole loop, no handoff gap.
