Open to meaningful, high-impact challenges—AI-native products and complex platforms
Open to meaningful, high-impact challenges—AI-native products and complex platforms
I design how product behaves,
not how it looks.
Hi 👋🏻, I’m Katherine Peng, I build AI-native products/systems where model behaviour, orchestration, and human trust matter.
I’m a principal-level Design Architect who turns ambiguous ideas into shippable interaction patterns. I define system behaviour, prototype fast, and build design systems that scale.
I take pride in my craft and mentor early-career designers, building strong relationships with cross-functional stakeholders. I thrive in complex, ambiguous environments and don’t just talk strategy—I lead teams to turn concepts into reality.
I bring end-to-end product expertise, from vision and strategy to discovery and delivery. Data-driven and focused on impact, I’ll collaborate with you to deliver impactful results.
I’m {highly_techsavy}, while (I’m != engineer) {I_know_my_way_around && speak_fluently_with_dev_teams}; I love collaborating with engineers (fun_fact: I married one) lol.

Insights from whose I've worked with
"I worked with Katherine for 3 years, she very quickly distinguished herself as a rising star with the wider BT Design family. She came in strong, but has now evolved exceptional design skills across UI, UX, Design system creation and AI process. Her growth mindset shows up in everything that she does. From the get-go Katherine took ownership of the redesign of a major platform. Later on, sensing the need for consistency and strong foundations, she took ownership (on top of her sprint work) of the creation of a UI Design system for the platform - learning the best practices around system architecture and tokenisation - while also driving the development team to create in a way mirroring her work What has always impressed me most about Katherine is her pace and versatility. She is fantastic in Figma, fabulous in Framer and awesome in AI. And her output is always well thought out, fast and never compromises quality. Beyond design, Katherine is a joy to work with. She is collaborative, open to feedback and incredibly positive. I hope we work together again. She’s one of the best designers i know."

“There’s never a dull idea when Katherine is in the room. She pushes boundaries in the best way possible, coming up with solutions that are not only beautiful but genuinely innovative. She doesn’t settle for ‘how it’s always been done’—she reimagines it. Some of our most creative features came directly from her ability to think differently.”
Carlos V
Senior Product Designer
“Every team needs a Katherine. When we hit a roadblock, she’s the one who calmly dissects the problem and finds a smart, actionable solution. She doesn’t just throw ideas around—she executes them flawlessly. Even in high-pressure situations, she keeps a level head and makes sure we deliver something that truly works.”

Senior Engineer
“One thing I appreciate about Katherine is that she always thinks a few steps ahead. In meetings, she anticipates challenges before they arise and comes prepared with solutions. She understands that good design is more than just UI—it’s about systems, workflows, and long-term impact. Her strategic mindset has shaped our design direction in ways we didn’t even expect.”

"Katherine is a super strong designer who leads with ingenuity, imagination and industry. She’s played a central role in shaping BT's global Network-as-a-Service experience, one of the most complex challenges we’ve taken on. She’s made sense of deeply technical requirements and turned them into clear, usable experiences that work for customers. She brings structure to ambiguity. She listens well, maps across the gaps, and has helped dozens of teams align around what matters. Her thinking is sharp, her craft is strong, and she delivers work that holds up under pressure. Katherine has also been way ahead of the curve in exploring how AI can change the way we work. She’s been testing tools, building workflows and designing with AI in the open long before others were paying attention. She’s grown quickly over the last few years, taking on bigger and bigger challenges, earning trust across disciplines, and showing what it means to lead through design. If you want someone who pushes thinking forward and gets the work done to world class standards, Katherine is that person."
