VolumeLeaders is a market-analytics platform that shows where the real money is moving: dark-pool blocks, sweeps, and unusual volume, with the context a trader needs to act. I led the product's UX and UI design and built its design system, turning dense, real-time market data into a clear, scannable interface.
Millions of trades print every day, and most trading tools bury the ones that matter. The signal that moves markets, large institutional blocks, dark-pool prints, and sweeps, is scattered across feeds and hard to read in time to act on.
VolumeLeaders exists to surface that signal: not more numbers, but the few trades and sectors that actually carry weight, shown clearly enough to act on at a glance.
The overview answers one question first: where is attention right now? I designed a scannable dashboard of biggest movers and most actively traded names, with sector heatmaps that size and color each stock by performance, so a trader reads the whole market in seconds before drilling in.
Color does real work here, so it had to be legible and consistent: a positive and negative scale that holds up in both light and dark themes and never relies on red and green alone.
The hardest view to get right was the chart. A single stock can carry thousands of trades, and a trader needs to see the ones that matter, a dark-pool block, a sweep, a late print, right on the price action, without the chart turning into clutter.
I designed trade markers that sit on the candles and open into plain-language detail: what printed, how big, at what price, and why it stands out. Each trade type has its own clear encoding, so the pattern is readable at a glance and precise on inspection.
This is the part I am proudest of. I built a full design system for the platform: color, type, and a library of reusable components, from buttons and cards to the complex data tables and heatmaps, defined once and used everywhere.
The system includes the data-specific decisions most design systems skip: positive and negative scales, indicator and heatmap palettes, and light and dark variants, all documented as front-end-ready components so engineering could build consistently and fast.
VolumeLeaders is the kind of problem I want more of: a dense, high-stakes, data-heavy product where the whole job is turning an overwhelming amount of information into a fast, confident decision.
Designing the product and the system behind it meant every screen stayed consistent as the platform grew, and every visualization earned its place by answering a real question a trader asks.
I design complex, data-heavy products and build the systems behind them. I can go as deep as the problem needs.
