The short version

Work, in plain view.

Tathagata Sarkar · Product Designer · Design systems & AI products

I care how things look, I build them in code, and I use AI where it actually helps.

Shipped storefront · Design system

Anubhuti India

Read full case study ↗

My role: identity, photography, product design, development and catalogue setup.

The Problem
A small saree label needed a coherent storefront and a maintainable system behind it. The source audit found undocumented tokens, repeated motion values and readability and focus gaps.
The limits
One designer and developer, the existing brand’s visual identity, and a live storefront. Library-dark is a demonstration; checkout remains an unreleased preview.
What I built
Primitive → semantic → component tokens. One versioned JSON source, an alias-resolving compiler, CSS outputs and a Figma library with parity-checked scalar values.
What happened
+395% orders a month, from 3–4 to about 17 through the website, by the founder’s count. Built, not shipped: 206/206 tokens documented and 93 → 0 hand-typed timings. Growth is not attributed to the design system alone.

Internal tool · Rights clearance

Clario

Read full case study ↗

My role: product design, the prototype, and the internal build’s interface and backend, with the repository team, IT and senior producers.

The Problem
Teams pick images before anyone has read the licences, so problems turn up mid-production and work gets redone.
The limits
Clario only reads, and takes limited data. Missing evidence must stay uncertain, and a person keeps every commercial decision. It runs on rules, with no AI.
What I built
One check before the ads get built. It reads every image’s dates and channels and marks it cleared, review or at risk. The public prototype runs on made-up records.
What happened
More than 15 campaigns in under two months, with dozens of producers. It found problems before production, on images reused from older campaigns. Rework savings aren’t measured yet.

Service design concept · Working prototypes

Fleet

Read full case study ↗

My role: service design, product strategy, interaction design and prototype development.

The Problem
A food truck moves, runs out and changes its menu. A restaurant-style listing hides the uncertainty a customer needs to plan around.
The limits
Location must be verified before discovery. Pickup slots must reflect kitchen capacity. A pilot must work for both the operator and the platform.
What I built
The stop is the product. When the crew updates where they are, what’s left or what went wrong, customers see it straight away.
What happened
Customer and crew prototypes that work together, taken to three truck crews in person. Whether it pays needs a small pilot; the numbers are made up.
