Turning scattered data into daily decisions for distribution teams

Analysts made daily decisions by piecing together data from four separate sources. I mapped their journeys, identified the flows that mattered most, and designed dashboards that adapt to their changing goals across the week.

The apps were a mix of analytical and operational, where the user had to take data-driven decisions after analysing and interlacing data from different sources. Hence, the dashboards had to be designed to adapt based on the changing user’s goals throughout their daily and weekly activities.

Fitness Startup

2023–2025

From UX audit to a redesigned app and a design system for iOS and web

1FIT is a fitness startup with a B2B2C model, which lets fitness coaches give their clients an app to track their progress.

I started with a UX audit of the iOS app: its main action, logging daily data, was buried two or three levels deep, and the app had no clear primary goal.

As lead designer, I redesigned the client app around daily logging and coach feedback, built a custom design system for iOS, and tailored IBM’s Carbon to the coaches’ web app, migrating the existing screens onto it.
