I design products
people trust — and
systems teams
can scale.

Lead Product Designer with 9+ years across Jio, PayU, and Infosys. I design AI products, scalable design systems, and enterprise experiences that move real metrics — CSAT 2.6→4.2, 71% engagement lift, 55% support call reduction.

Three things I believe about design — deeply.

Principle 01

Systems before
screens.

A beautiful screen that breaks in context B or fails under scale is not good design. I start with architecture — how components connect, how decisions propagate — before I design a single pixel.

Principle 02

Evidence over
instinct.

My instincts are a starting point, not a conclusion. Every significant design decision I've made has a research artifact behind it — an interview, a journey map, a usability test — that grounds the rationale.

Principle 03

Constraints are
creative fuel.

Enterprise products are full of constraints — technical debt, legacy systems, competing stakeholder needs. I've learned to treat these as design challenges, not blockers. The best solutions emerge from inside the box.

Career
timeline.

A progression from pixel-pushing to systems thinking and design leadership — with increasing scale and complexity at each step.

Beyond the work.

I'm a photographer at heart — it's how I learned to see: light, composition, the decisive moment. That obsession with framing has followed me into product design. Every screen is a composition. Every user flow is a story with a beginning, tension, and resolution.

When I'm not designing products, I'm exploring Bengaluru's architecture or thinking about why some designed objects feel inevitable and others feel forced.
