Design Leadership — Product, AI & Enterprise Experience — 18+ years

Designing for today.
Shaping what comes next.

I'm a Design Leader with 18+ years turning ambiguity into products and platforms that are clear, useful, and built to scale — from legacy enterprise systems to AI-driven tools. Increasingly, my focus is a newer kind of design challenge: making intelligent systems understandable, trustworthy, and genuinely useful. Beyond the product, I build and grow the design teams that make that possible.

Selected work

A working index, not a highlight reel.

Three projects that span the full range of the job — modernizing a legacy enterprise system, redesigning a B2B web presence, and designing AI-guided tooling for real-world craftspeople.

  1. 01 Bridgital Loom — AI guidance for handloom weavers Contributed to the design of TCS's Bridgital Loom, an AI-powered initiative that pairs a smart loom with real-time LED guidance so weavers can follow complex patterns without memorizing long sequences — tackling a handloom sector where up to 40% of finished pieces are returned over design and execution errors. Showcased at the India AI Impact Summit 2026. AI Product Design Hardware + Software UX Social Impact 2023–Present · TCS
  2. 02 Copa Airlines — from mainframe screens to digital Owned the end-to-end UX for Copa Airlines' transition off legacy mainframe workflows while leading UX at MphasiS — research, design, usability testing, handoff, and dev support — as part of a broader portfolio of regulated airline and insurance work including United Airlines and AIG Valic.

  3. 03 TÜV SÜD — a website redesign built for trust at scale Led the full redesign of TÜV SÜD's corporate website while at Verticurl — a regulated brand with many stakeholders to keep aligned — from early research through shipped design, and built the design system and UX guidelines the team still works from.

Design philosophy

A lens I've sharpened for 18 years, not a slide I memorized.

I've designed for airline agents reading green-screen terminals, for weavers guided by AI and LED light instead of memory, and for engineers trying to find one certification standard on a website built for a different era. The common thread isn't the industry — it's translating something genuinely complicated into something a person can pick up and simply use.

Start where the friction actually is

Not where the brief says it is. On Copa Airlines, that meant sitting with the workflow itself — a legacy mainframe screen — before touching a single new interface.

Design for the person doing the work, not the demo

Bridgital Loom only works if a weaver trusts an LED light over years of memorized technique. That's not a UI problem — it's a trust problem, solved through design.

Structure around intent, not org charts

On the TÜV SÜD redesign, the fix wasn't better visuals — it was reorganizing the site around what buyers were actually searching for, instead of how the company is internally structured.
