Overview
Calculum provides a web platform that empowers companies to optimize payment terms and cash flow, helping them stay competitive in an increasingly complex financial landscape.
My role as Lead UX/UI designer was ensuring a structured, intuitive, and scalable design framework. Enhancing data visualization principles to improve engagement and comprehension. Overseeing the development of an evolving design system to support platform growth.


Improving Clarity, Efficiency, and Data Accessibility
Financial data platforms must balance complexity with usability. The initial platform faced key challenges:
Apply Data Visualization Principles
Consider the data type, minimize visual clutter, effective use of color. Intuitive charts improved readability for a data-heavy audience accustomed to numbers and tables.
Manage Complexity with Progressive Disclosure
Cognitive overload was reduced by revealing less frequently used features only when needed (via visual hierarchy, hover, click, or expansion states).


Financial Strategist – Mark Schwartz
"I need the right insights fast. I don’t have time to dig through endless tables—just show me what matters."
Behaviors
Goals
Quickly extract key insights on suppliers, payment terms, and financial impact.


Frustrations
Cognitive overload, inefficient data filtering, excessive scrolling in long tables.
Role: VP of Finance / Treasury Manager / Procurement Director

Key issues

⚠️ Alert & notification fatigue
This can have serious consequence as diminish attention. That defeats the purpose of the dashboard, which is to provide timely and actionable insights.
⚠️ Unite systems
Providing a global overview offers an at a glance snapshot of what's going on. A common pain point is navigating multiple data sources and disjointed systems.
How might we help users focus on their progress without feeling overwhelmed by notifications, recommended actions and disjointed systems on the dashboard?


✅ Map out user context

How might we visually highlight key data points to reduce cognitive load and improve scalability?
Legacy Platform Design: Usability and Scalability Issues


⚠️ Layout
Platform's rigid layout limited scalability, hindering the inclusion of new metrics for deeper data analysis.

The geolocation chart's visual dominance diverted attention from other essential data, demonstrating a poor visual hierarchy.
⚠️ Gaze tracking
Low contrast and incomplete labels ("Med") impeding accurate interpretation.
⚠️ Chart data accessibility
Instant context for insights
Users need to quickly understand the purpose and potential benefits of each each screen.


⚠️ Hierarchy
Users struggled with interfaces lacks a clear hierarchy and layout.
⚠️ Inconsistent UI Styles
User requires to learn different ui-patterns which hinders learnability.
⚠️ Clutter
Old platform design
Users need quick supplier identification with key details visible at a glance.

✅ Key findings
Heatmaps & gaze tracking provided insights on which sections users focused on. Identified the top insights to the user, optimizing their hierarchy and usability.


Stage 3: HMW Analyzing Opportunities
How might we prioritize the most critical supplier details without overwhelming the user?
Usability Study
Inefficient Supplier Cards: Users wanted quick supplier identification with key details visible at a glance.
✅ Gaze point on screen
Z-Pattern: User focus on scanning the entity name and logo in a Z-pattern" as they scroll down the list.


Cluster of information takes longer for the user to scan and navigate.This does not optimize the flow.
⚠️ Difficulty readability




✏️ Drilling into information
Drilling further into the information to reveal more detail, reference something or double-check information is an important part of the experience in a dashboard. This is the part where users are free to explore more and discover and really “use” the data. If people want more, that’s usually a good sign.
