About

I design for the moment that matters.

Arnab Debnath

At JUSPAY, that moment is checkout — when someone is deciding whether to trust a product with their money. I've spent the last few years making that moment shorter, clearer, and less scary for millions of users.

I came to design through engineering and art. I studied Computer Science, which gave me a strong opinion about how systems should work. I painted, which gave me a strong opinion about how things should feel. Those two instincts don't always agree — the tension between them is where my best work comes from.

I work closest to PMs and engineers. I read PRDs before wireframes. I flag edge cases before usability tests. I've shipped prototypes myself when words and mockups weren't enough to land the idea.

Right now I'm exploring how AI changes the research-to-design loop. Not the tools — the thinking. What does it mean to synthesize 100 user interviews in an afternoon? What decisions can you make faster, and which ones still need slowness?

Outside of work: painting (always), reading about systems design, and building things that probably won't ship.

Beyond the Pixels

What fuels the work

Design doesn't happen in a vacuum. These are the things that shape how I see, think, and create.

Building

Side projects, tools, experiments. I'm founding uiMate — a career growth platform for designers. If it doesn't exist yet, maybe I should make it.

Recently I've been coding a lot more — not just prototypes, but actual production contributions. It started as a way to better understand interactions and animations, and turned into a habit. Understanding implementation constraints firsthand makes my design decisions sharper.

Painting

Fine arts trained. I still paint when I need to think without words — acrylics, ink, sometimes just charcoal on brown paper.

Gaming

Story-driven games are my design school after hours. Every menu, every onboarding, every micro-interaction — I notice them all.

Travelling

New cities reset my creative palette. I collect wayfinding systems and street typography the way others collect magnets.

The gap between a designer and an engineer is where I do my best work.
