I started in experimental typography and visual aesthetics, then spent the next 15 years building digital products across airlines, logistics, finance, pharmaceuticals, and commercial real estate. Each industry taught me something different. Airlines demanded precision at scale, logistics required clarity under complexity, finance needed trust through consistency, and real estate pushed me to rethink how enterprise platforms serve their users.

That arc shaped how I work today. I lead design teams with mentorship and clear goals. I own enterprise design systems, lead platform redesigns, and integrate AI into product workflows, from ideation through prototyping to production. Currently, I lead product development for facility management platforms at JLL Technologies (JLLT), where I design AI-enhanced features that help teams make better decisions faster.

My background in aesthetics, scientific processes, and experimental typography still shapes everything, how I think about design systems, how I write, and how I approach emerging technology. I see AI not as a replacement for craft, but as a new material to work with.

Design Philosophy

I believe great product design is invisible infrastructure. It should reduce cognitive load, not add to it. Every interface is a conversation, the system speaks through layout, type, motion, and silence. My job is to make that conversation clear.

AI changes what's possible in that conversation. I design products where AI augments human judgment rather than replacing it, surfacing patterns, automating the tedious, and keeping people in control of decisions that matter. The best AI features are the ones users barely notice because they just make the product smarter.
