SC.01 — THE THREAD

2014 — 2018

The foundations

Future Beyond and Neplar Corei — WordPress builds, then front-end development and senior UI design. I learned design and code as one job before the industry decided they were two.

DESIGN-TO-CODE FROM DAY ONE

2018 — 2021

The craft years

Three years at Protopillar: end-to-end interfaces, journey maps, personas built from primary research, and analytics-driven iteration. The unglamorous reps that make judgment fast later.

2021 — 2024

The proving ground

A rapid sequence — Vivoiz Healthtech, a design system from scratch on contract at AI Enterprise, a UX audit of a major property platform at CX100 that surfaced 30+ critical gaps, then independent consulting. Different domains, same brief: something is too complex, and people have to use it anyway.

2024

Principal, proven

Principal UX Designer at Seanergy Digital. A research-led redesign of core product interfaces — moderated and unmoderated testing cycles, synthesized into changes the engineering team actually shipped.

The system at scale

Staff UX Designer (Design Lead) at Alshaya Group. I own design strategy for a multi-brand retail platform ecosystem — and architected the design system that holds it together: 200+ standardized components across 6+ product surfaces. First product shipped within 3 months of joining; adoption rose 35%.

SC.02 — THE ITCH

So I started shipping my own.

Some shipped. One didn’t. All of it is the point.

SC.03 — THE SYSTEM

One design language, six surfaces, two hundred components.

Tokens before components.

SC.04 — THE METHOD

Strategy by me. Execution by agents. Judgment throughout.

SC.05 — THE BET

Design is leaving the screen.

The interfaces I’ve spent twelve years designing assume a human is looking at them.

That assumption is expiring.

AI agents now read, navigate, and act on digital products directly — which means experience design is becoming architecture: structuring systems so that both humans and machines can use them well.

That’s the bet my work is converging on.

I’m not waiting for it to be obvious.
