Real-time trading screens, where it started

Started my career at IFP building real-time trading UIs: reusable screens, interactive data tables, and live-updating charts that turned dense financial data into something traders could act on.

Before the platforms and the org charts, there was the screen a trader stared at all day. I started my career at IFP building the real-time UI for a fintech trading platform, and it taught me a lesson I never unlearned: the interface is where the system meets the money.

What I built

  • Reusable trading screens. Componentized the trading surface so new instruments and workflows could be assembled instead of rebuilt, which is how a small team kept pace with a fast-moving product.
  • Live data, live menus. Built interactive data tables, charts, and live-updating menus that reflected the market as it moved, not a snapshot from a few seconds ago.
  • Data into decisions. Turned dense, fast-changing financial data into intuitive, actionable interfaces that improved how traders actually worked.

Why it stuck with me

In trading, a slow or wrong screen is not a usability nitpick, it is a loss. Latency you can feel, numbers you can trust, and a layout that gets out of the way under pressure. The standards I hold platforms to today started here, at the last few pixels before a human makes a call with real money.
