Selected projects

Seven projects across Windows, AI, Search and Health. Chosen to show how I frame ambiguous product spaces, design for trust, and ship systems that survive real-world scale.

Windows Drop TrayTurned everyday file dragging into one fluid, intent-aware gesture at 1B+ Windows scale. Windows' first interaction patent, built to a Gold accessibility bar.2026WindowsProduct DesignAccessibilityA rework of one of Windows' oldest gestures, designed to reduce friction in a behavior people perform more than 10B times a month. The work shipped to retail preview, reached a 50% rollout in India, and became my first patent in Windows.Read Case Study Reshaping Windows HelloReshaped Windows Hello so signing in feels effortless and assured, removing that jarring moment your own computer fails to recognise you.2026Windows HelloProduct DesignSystem UXA redesign focused on making Windows sign-in feel faster, more reliable, and less frustrating in real-world conditions, especially in low light and other moments where the experience used to break down.Read Case Study From Health Search to Health JourneysShifted Bing and MSN Health from a clinical search engine into a calm, credibility-first journey. Scaled to 5.8M daily users, earned a patent, and was demoed to Satya Nadella.2024Health SearchProduct DesignMobile UXBuilt to make health search more credible, connected, and useful across surfaces rather than treating each query as a dead end. The platform scaled to 5.8M daily users, 22 markets, and a #1 health publisher position.Read Case Study Trustworthy Health AI AnswersAuthored the patented trust framework that lets generative AI answer health questions naturally while staying grounded in expert facts, across MSN, Bing, and Copilot.2024Health AIProduct DesignTrust & SafetyDesigned for a category where fluency alone is dangerous and every answer needs clear grounding. The system achieved more than 90% health-intent coverage and carried from MSN to Bing to Copilot without a rebuild.Read Case Study HVS: Measuring Windows CraftCo-created a framework that scores whole user journeys, not isolated screens. Now used across three orgs to measure and lift Windows craft.2025WindowsDesign StrategySystems ThinkingCreated to help Windows teams evaluate experiences as journeys, not isolated screens. It introduced a shared quality model around Think, Feel, and Act, with targets like Think > 4.5, Feel > 85%, and Act > 95%.Read Case Study Phone Link: No Dead EndsDesigned a silent background flow that installs the missing app in a single tap and instantly resumes your conversation, with no dead ends across devices.2024Windows ShellSystem DesignPlatformAddressed a structural gap in how Windows handled communication flows across devices and entry points. The pattern closed dead ends across toast, tray, and Action Center, and was later reused in People Widget and WhatsApp on Windows.Read Case Study Healthcare Ads Without Breaking TrustDesigned a clean, action-first health ad unit for Bing. Call a clinic or get directions straight from the result, helpful without ever feeling intrusive.2023Healthcare AdsProduct DesignLocal IntentBuilt for moments where monetization only works if the experience still feels useful and trustworthy. The format helped drive $69K ARR from 11 advertisers while keeping provider discovery clear, local, and action-oriented.Read Case Study

[What I bring]

A fit for AI, Search and platform teams.

I bring a decade of product design experience across Microsoft, enterprise software, banking, logistics and edtech. The last 5 years have been at Microsoft, designing Windows, AI, Search and Health systems where trust, clarity and scale all matter.

01

AI Experiences People Understand

Designing flows where users know what the system did, why it did it, and what they can do next.

02

Product Sense and Business Value

Understanding what matters to users, what matters to the business, and where design can turn both into a clearer product direction.

03

Platform Interaction Design

Creating patterns that hold across surfaces, entry points, device states and accessibility needs.

04

Trust, Safety and Quality

Working in domains where unclear, ungrounded or unreliable UX can quickly break user trust.

05

Systems Thinking at Scale

Connecting user needs, technical constraints and product strategy across products used by millions.

06

Leadership Through Ambiguity

Turning fuzzy problem spaces into directions that PM, engineering, research and leadership can act on.

[Experience]

A track record across platform, AI and enterprise.

[ Microsoft ]

Product Designer, AI & Windows

I author patented, OS-level interactions for Windows at billion-user scale and pioneered the Generative AI trust framework for Health, serving 5.8M daily users. My work sets strategic design standards across three Microsoft organizations and has been showcased at Microsoft Build, covered by popular media, and demoed to executive leadership like Satya Nadella.

[ Previous ]

Product / Enterprise / Consumer Design

Temenos, BYJU'S, WongDoody, and more across enterprise software, banking, logistics, education, and digital product ecosystems.

[ Community ]

Mentor, speaker, writer, podcaster

As the author of Nodes of Wisdom and host of India's top-charting design podcast, I scale AI design literacy to millions. Beyond mentoring 800+ designers globally, I actively shape industry talent on the ground through masterclasses at various IITs and institutions, and organize non-profit events like Manifest and Coffee & Computing to keep technology human.

[Outside the work]

I stay close to making, learning & conversations.

Outside product design, I keep following the same things that pull me into good work: craft, systems, stories, and the small rituals that keep technology feeling human.

01Making

Experiments, data art, and little tools.

I like thinking with my hands: visual systems, small prototypes, sketches, and data-led pieces that turn complexity into something you can feel.

Data art exhibited across Serbia, Africa and India
02Conversation

Podcasts, writing, and questions that travel.

I learn by talking to people who see the world differently, then turning those conversations into notes, essays, podcast episodes, and usable lessons.

Nodes of Design, 100+ episodes across 60+ countries
03Community

Mentoring designers and making AI less distant.

A lot of my energy goes into helping designers grow, and into teaching AI in plain language for people who do not usually get invited into the room.

800+ designers mentored globally; AI in Telugu for millions
04Rituals

Chai, running, bikes, cameras, watches, golf.

I collect small ways to reset my attention. Chai before a hard brief, running when the thinking is stuck, photography for seeing better, and objects that teach patience.

The hobbies are not decoration; they are how I keep my eye tuned
