Why hire me
The kind of designer
you're actually hiring.
Not a pixel-pusher, not a slide-maker. Five places I create outsized value on complex products.
Complex platform & admin UX
I make dense, permission-heavy enterprise tools genuinely usable — RBAC, admin consoles, and the data-heavy workflows most designers avoid.
Design systems from scratch
I build the system and its components, so design intent survives all the way to production — not just to a tidy Figma file.
AI-augmented, design-as-code
I don't stop at specs. I prototype and ship production-ready screens with AI in the loop — a workflow now running on three platforms at Gainsight.
0 → 1 in ambiguity
My best work happens where the problem is genuinely unclear and there's no roadmap to follow. I find the structure before touching an interface.
Cross-functional leadership
I hold product coherence across engineering, PM, and design — and keep holding it when leadership turns over mid-project.
Selected for G1 Elite— one of 12 chosen company-wide from Gainsight's top performers, following an Unmatched Excellence (top-tier) performance rating.

Research-grounded. AI-augmented. Engineered to ship.

Industrial Design
Engineer turned
Senior PD.
Industrial Design Engineering taught me to start with constraints, not aesthetics. Street photography taught me what to include and what to cut. Eight years of complex products later, both still run everything I do.
I work best where the problem space is genuinely ambiguous — consolidating competing platforms, designing permission systems that scale, holding product coherence when the brief is incomplete.
Design philosophy
Most interface problems are architecture problems in disguise.
Research doesn’t confirm what I think, it generates questions I hadn’t thought to ask.
The hardest design work happens before a screen is drawn.
