The Strategic Challenge: Expanding Beyond Mobile

By 2021, BUX’s mobile app had achieved remarkable success with 1M+ users across Europe. But our data revealed a critical opportunity: users wanted advanced features that were better suited for larger screens—detailed portfolio analysis, complex charting, and educational content.

As Product Manager, I was tasked with bringing BUX to the web while maintaining our mobile-first DNA and user experience excellence.

BUX Web App

The Product Strategy: Complementary, Not Duplicate

The Insight: Web wasn’t just a bigger mobile app. Desktop users have different behaviors, needs, and interaction patterns.

My Approach:

  • Mobile: Optimized for quick trading, notifications, and on-the-go portfolio checks
  • Web: Focused on analysis, research, and educational content consumption
  • Seamless Integration: Real-time sync between platforms with consistent data and user state

Design Innovation: Rethinking Information Architecture

The Challenge: Mobile apps use sequential navigation (swipe, tap, navigate). Desktop users expect simultaneous information access.

My Solution: Developed a unified dashboard that combined multiple mobile screens into one comprehensive view:

  • Live portfolio performance
  • Real-time watchlist updates
  • Integrated news feed
  • Advanced charting tools
  • All visible simultaneously without context switching

Building the Right Team

The Leadership Challenge: We needed to build an entirely new engineering team specialized in web technologies while maintaining our mobile-first culture.

My Approach:

  • User-Centered Focus: Ensured both teams prioritized user experience over technical preferences

The Results: Expanding Market Reach

User Growth:

  • 40% increase in user engagement across platforms
  • 25% of new users now start on web before adopting mobile
  • 60% of power users regularly use both platforms

Product Impact:

  • Educational content consumption increased 200%
  • Professional traders began choosing BUX over traditional platforms

API Strategy: Led the development of unified APIs that served both mobile and web, reducing development complexity and ensuring feature parity.

Performance Optimization: Applied mobile-first performance principles to web, achieving faster load times than traditional desktop trading platforms.

Responsive Design: Ensured the web platform worked seamlessly across desktop, tablet, and even mobile browsers.
