Turned dragging a file into one fluid, intent-aware gesture at 1B+ Windows scale, a behaviour people perform more than 10B times a month. Shipped, built to a Gold accessibility bar, and named inventor on Windows’ first interaction patent granted in India.
Read case →Reshaped Windows sign-in so face and PIN run in parallel, removing that jarring moment your own computer fails to recognise you. Designed for the real conditions where Hello used to break down, low light most of all.
Read case →Shifted Bing and MSN Health from a clinical search engine into a calm, credibility-first journey. Scaled to 5.8M daily users across 22 markets, reached a #1 health publisher position, earned a patent, and was demoed to Satya Nadella.
Read case →Authored the patented trust framework that lets generative AI answer health questions naturally while staying grounded in expert sources. Over 90% health-intent coverage, and it carried from MSN to Bing to Copilot without a rebuild.
Read case →Co-created the human-centric framework that shifted the unit of quality from isolated screens to end-to-end user journeys. Evaluated on Think, Feel, and Act, it is now adopted across three major organizations to measure and systematically elevate Windows UX craft.
Read case →Transformed the Windows sharing flyout into an inline creation canvas. Built cropping, markup, and compression directly into the sharing surface, enabling users to polish and tailor content for its destination without app-hopping.
Read case →Designed the multi-surface healthcare ad framework powering monetization across Bing and MSN. Unified provider directories, clinical services, and drug search results into high-utility, action-first experiences enabling direct scheduling and clinic contact while driving $690K ARR.
Read case →Designed a frictionless background flow that installs missing apps in a single tap and seamlessly returns users to their active conversation. Eliminated critical UX dead ends across Toast, Tray, and Action Center, creating a pattern now adopted by People Widget and WhatsApp on Windows.
Read case →Reframed technical debt as experience debt, shifting focus from static screens to end-to-end user scenarios. Mapped 85% of legacy cruft onto real journeys and modernized 100+ native dialogs to WinUI 3, including core system surfaces powering 122M monthly active devices.
Read case →Invented a search interaction pattern that surfaces vetted human expertise at the exact moment of intent. Served as sole designer and researcher; patented the core interaction model, which directly powered a sibling surface generating $1.5M ARR.
Read case →Led design for explainable AI ranking in Windows share recommendation systems. Designed an interface that transparently communicates why items move, maintains spatial stability, and leaves final agency with the user, building AI trust through human control.
Read case →Designed the mobile COVID-19 tracker for Bing, turning a global crisis response into a life-saving resource for 20M daily active users. Shifted the UX from passive data dashboards to immediate, high-intent actions, enabling millions to instantly locate testing sites, access critical health guidance, and contact emergency resources.
Read case →Built a location-first vaccine tracker for India during peak pandemic demand, seamlessly guiding citizens from high-anxiety search queries directly to verified local centers and registration pathways. Scaled rapidly to serve 120–140K daily active users when access was most critical.
Read case →Architected the core information architecture and navigation for the Activity Hub used daily across 3,000+ global financial institutions. Reorganized complex enterprise workflows around Orient, Decide, and Act, substantially lowering decision time for bankers and driving measurable improvements in ease of use.
Read case →Designed an end-to-end corporate lending platform, onboarding through facility tracking, as a single banker canvas across five systems. Multi-million-dollar loans stay legible at every stage instead of fragmenting between tools.
Read case →Built a token foundation and modular component system that banking teams could actually use without forking the code. Added a clear governance path for edge cases, driving system adoption way beyond the original team that built it.
Read case →Interviewed leaders across 9 global banks and turned 40+ conversations into a 3-tier framework for AI authority and human control. The framework shaped 6 product roadmaps, 2 strategy cycles, and placed Top 6 at the Temenos Global Hackathon.
Read case →Redesigned freight quoting around live customer calls, letting automated logic handle the math while sales reps stayed in control of final judgment. Boosted cross-sales by 34% and improved booking efficiency by 42%.
Read case →Designed the operator load boards, freight tracking, and capacity tools for XPO’s digital freight marketplace, built specifically for fast-paced shift work instead of passive dashboard monitoring. Recognized with an SDC&E 100 Supply Chain Award.
Read case →Led design and research on a creator-first daily progress tool for a 120-person content team. Made tracking work feel natural for creators while giving management clear planning signals, doubling team productivity and pushing goal completion past 80%.
