Testimonials

Hari is adept at navigating complex, interdisciplinary teams. For our e-textile devices, he actively listened to both patients and healthcare collaborators to build an interface that people could actually use easily without frustration. His work was practical, and he delivered it to a high standard.

In complex enterprise platforms, great UX is never merely a visualization layer, it is about connecting dense data to real operational context. Hari understands this balance instinctively. He brought structure to our platform by turning complicated system workflows into clean, intuitive experiences without losing the underlying logic.

About

I have most of my career working on products where the details matter because people rely on them, whether that means taking part in a health study, learning maths or managing a building. I enjoy moving between research, product thinking and interaction design, especially when a messy problem starts to become something a team can reason about and build.

Away from work, I photograph everyday scenes and small details. Observation has always been part of how I make sense of things, and it inevitably finds its way into how I design too.

How I work

I tend to look beyond the interface first. When people hesitate, repeat steps or create workarounds, I want to understand the workflow, constraints and system behaviour underneath before deciding what should change.

I prefer decisions that can be explained, tested and carried through with engineering, rather than polished screens that solve only the visible part of the problem.

Currently developing

Executable product modelling

Using AI to express product logic, workflows and states as functioning interfaces, making complex ideas tangible and testable much earlier in product development.

Design systems as product infrastructure

Connecting tokens, components, interaction rules and accessibility standards into a governed system that keeps design and implementation coherent as products and teams scale.
