I've worked with over 50 amazing organizations. Below are some projects I'm proud of.


UX/UI design and user research for a new product for monitoring antibiotic resistance

Resistomap is a startup building a novel tool for monitoring antibiotic resistance. Antibiotic resistance is a growing concern, projected to cause as many as 10 million deaths annually by 2050. I helped in interviewing customers and potential users to dig out the actual user needs for the tool.

I designed both high-level decision-maker views and updating designs for data analysis views for experts. Finally, I unified the visual styles to match the new branding of Resistomap by creating a minimal design system for them.

Design and development of a completely new way to create brand and product design automatically using AI

Duotone is an automated design tool I'm building with two goals. First, simplifying the creation of minimal brand designs for startups; second, automating and streamlining the transition of designs into production.

A few years back I created a demo of an automated design tool, called UIBot. I was surprised by the visibility it got, with thousands of retweets and hundreds of thousands views. Duotone is an extension of this work.

FNA Correlations

New product design and user research for FNA, a market leader in analyzing graphs of financial transaction data

I started working with Financial Network Analytics (FNA) when they only had a simple prototype and no real user interface. The aim of the initial project was to create interfaces for the applications that look professional and are easy to use, but provide a wide range of advanced analytics tools.

The new designs got excellent feedback from both customers and investors, enabled FNA to become one of the leading risk analytics companies for central banks, and helped in securing investor interest and financing.

The collaboration started with a five-day UI re-design project. FNA was satisfied with the results of the initial project and decided to continue with collaboration. Over five years I designed the user interface for all of the web-based applications of FNA.

I think a lot of people see simplicity as the lack of clutter. And that's not the case at all. True simplicity is, well, you just keep on going and going until you get to the point where you go, 'Yeah, well, of course.' Where there's no rational alternative.

— Jonathan Ive

Simplicity is about subtracting the obvious and
adding the meaningful.
