Adarsh Raj Shah
Senior Product Designer · AI & Mobile UX

Product designer with 7+ years shaping AI-first mobile experiences at Microsoft, serving hundreds of millions of users across the Microsoft 365 Copilot mobile app. I take ambiguous, large-scale problems from strategy to ship, grounding decisions in research and telemetry, and building reusable interaction systems that measurably improve engagement, activation, and retention.

Microsoft 365 Copilot mobile app: AI-native interfaces for iOS & Android. End-to-end ownership across strategy, research, interaction, motion and ship.
Dynamic Action Bar (DAB) in File Previewers

Designed a persistent, context-aware Copilot entry point inside Word, Excel, PowerPoint & PDF previewers — the most-visited surface in Microsoft 365 mobile. Scaled one interaction pattern across every previewer, setting the standard for how Copilot surfaces in document-centric experiences.

Impact: ~2% → ~15% Copilot engagement
New User Onboarding, Microsoft 365 Copilot mobile app

Rebuilt the first-run experience around a single "first prompt succeeds" moment, lifting consumer Week-1 activation 1.6–1.8× with zero retention regressions across iOS & Android. Owned strategy, prompt design and end-to-end flows, reversing a declining first-time-prompting trend.

Impact: ~40K net-new weekly users, no acquisition spend
Proactive Assistance & Daily Brief

Created a scalable UX framework for proactive AI nudges inside the Microsoft 365 Copilot app — shifting the experience from reactive to ambient intelligence. One entry point surfaces the daily brief, meeting prep and catch-ups before users think to ask, with ~2:1 positive feedback in early rollout.

Impact: one framework powering 3+ proactive scenarios
