Lynx Beleggen.

The Situation

Lynx Beleggen operates an online trading platform serving retail investors. The frontend had been built incrementally over years, with real-time data feeds, complex order flows, and regulatory requirements layered on top of an architecture that was never designed for that complexity. Years of quick fixes and feature additions had made the codebase increasingly difficult to maintain and extend.

The UI no longer reflected the quality of the product underneath it, and the development team was spending more time working around the existing code than building new features.

What We Did

Rather than attempt a gradual refactor of a fundamentally mismatched architecture, we opted for a full rebuild.

Architecture. We designed a new component architecture from the ground up, purpose-built for the demands of a trading platform: real-time data rendering, complex stateful workflows, and the performance requirements of financial applications.

User experience. We worked closely with the product team to redesign the core trading experience. The goal was to strip away accumulated complexity and deliver an interface that was intuitive for new users while powerful enough for experienced traders.

Development workflow. We established modern tooling, development standards, and a component structure that would scale with the product rather than against it.

The Result

A rebuilt trading platform with a modern architecture, a significantly improved user experience, and a codebase the team could confidently extend. The new foundation eliminated the constant friction of working around legacy decisions and freed the team to focus on product development.
