About my experience

Earlier work spanning enterprise workflows, consumer mobile and desktop products, branding, and visual design.
Sentinel E-Sitter
Helping people act on AI alerts with confidence.
Sentinel was a browser-based application for remote patient observers monitoring up to nine hospital rooms during its pilot. AI detected fall-risk behavior, while trained e-sitters remained responsible for validating alerts and coordinating the human response.
As lead UX designer, I owned the visual and audible risk states, validation controls, response timer, assignment workflow, and event lifecycle. I worked directly with frontend, backend, and QA partners and tested the experience with approximately eight participants.
