Alongside my work on the banking app, I took part in the redesign of the most popular trading app in Belgium, which had a significantly outdated interface. Our team of a UI designer, a UX designer and me spent three to four months on it, as part of my work at KBC Belgium.
Status: redesign project of three to four months, 2022 to 2023.
Team: one UI designer, one UX designer and me.
The challenge
Trading apps are complex: real-time data, fast actions and money at stake. The old interface had to become visually pleasing and convenient, and work for beginners as well as seasoned traders.
My approach
Research before design
We started with a deep exploration of how trading mechanisms and applications work, studying a broad range of trading platforms and apps. That showed us the best practices and the features worth bringing into Bolero.
A collaborative process
The redesign was highly collaborative. We met every two weeks with development teams, business stakeholders and analysts, which aligned the design vision with technical and business requirements and allowed iteration on continuous feedback.
What the redesign covers
Key parts of the redesign include real-time market data, intuitive navigation, efficient trade execution and robust portfolio management tools. Security features were emphasised to protect user data and transactions.
Key challenges
Two audiences in one interface
Beginners need guidance, experienced traders want speed. The design had to serve both without making either group wait or guess.
Balancing design, tech and business
Bi-weekly sessions with developers, stakeholders and analysts were the main tool for keeping design ambition inside technical and business limits.
What I learned
The importance of collaboration, the intricacies of financial app design, and the value of efficient design operations in a large organization.
Results: specific figures can’t be shared for contractual reasons.
