About me

Where design meets engineering

I'm an AI-native UX designer and design engineer who works at the intersection of machine intelligence and human-centred design. I don't just hand off specs — I build what I design.

My practice spans interaction design, prototyping in code, and AI product strategy. I've shipped AI features across conversational interfaces, generative tools, and data-heavy dashboards.

I believe the next generation of great products will be shaped by designers who can think in models, prompts, and components simultaneously.

How I work

My design engineering process

I move fast between research and production — collapsing the design-to-code gap at every stage.

01
Discover
Research the problem space, user mental models, and AI capability constraints.
02
Frame
Define interaction principles and where AI adds signal vs. noise for the user.
03
Prototype
Build in Figma and code simultaneously — test with real model outputs early.
04
Ship
Deliver polished components, specs, and documentation ready for production.
