I'm Hari. I design products across healthcare, education and enterprise systems, where repeated hesitation and workarounds usually point to a deeper product problem. Most of my job is reading those signals and deciding what the product needs to do differently.

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.

During knowledge management project, Hari showed he could take rigorous research data and translate it into coherent workflows. He is a capable designer who truly takes ownership of his work. He even stayed engaged through handover, making thoughtful follow-up refinements where they added value.

Led a team of two designers in redesigning a self-administered mobile experience ahead of a pilot study. Research showed the existing experience was too superficial and repetitive to sustain engagement, so I introduced more considered interaction patterns and personalisation while working closely with principal investigators and engineering to keep the experience both clinically appropriate and feasible to build.

Co-led UX for an engagement redesign aimed at helping children build a more consistent learning habit. Research and usability testing with students aged 6–16 informed new motivation, progress and reward mechanics, which were repeatedly tested and adjusted when we saw the incentives changing learning behaviour in unintended ways.

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.

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.
