Case Studies
Design and engineering work from Cisco, plus independent projects exploring simulation and AI.
Navigation redesign & search usability testing
The help center's navigation was designed for a smaller product suite. When Webex grew to dozens of products, I redesigned the structure to scale and ran a comparative usability test that showed the new search pattern was 38% faster.
UX & Researchcase study 02featuredAgentic search for a 3,000-article help center
With 3,000+ articles across dozens of products and user roles, Webex help center search was giving users answers they didn't trust enough to click. I designed and prototyped an AI layer that could earn that trust.
UX & Full-Stackcase study 03An AI bridge between writers and the CMS
Our tech writers were spending more time fighting CMS plumbing than writing. So I built DARIA — an AI bridge between their editor and the CMS — and cut the busywork around finding and assembling content by roughly 3×.
Design & AI Toolingcase study 04LLM Fortress: a living simulation where the AI doesn't drive
Most LLM-powered games hand the model the keys to the world — and inherit its latency, cost, and unreliability. I built the inverse: a deterministic simulation owns every decision, and a self-hosted LLM is constrained to giving its agents a voice.
