The right algo, every time.

Every bank's algos. One recommendation.

Graphene takes all of the algos subscribed to the platform, from the major investment banks and trading firms, and presents the trader with the most optimal way to work their order.

Some orders need speed. Some need the best price. Most need a balance. I joined as the founding Lead UX designer to design the end-to-end experience.

Brilliant ideas, scattered across spreadsheets.

Algo execution is a highly complex subject. The product's thinking lived in complex Excel spreadsheets full of calculations and illustrations of algo dashboards.

Many senior stakeholders, each an expert in their algo craft, brought strong and sometimes conflicting opinions. Many of them were great ideas. None of them yet added up to one product.

Turn the spreadsheets into a shared language.

I worked through the stakeholders' spreadsheets to understand the calculations behind each idea, then brought everyone together to agree what a trader needs to see, and when, to choose with confidence.

That became the backbone of the product: an order's objective, the market conditions around it, and the evidence for each algo and liquidity provider.

From order to outcome in one flow.

Orders move through a clear lifecycle of New, To Do, Working and Done. Each row shows the primary objective, compact liquidity, momentum and volatility signals, a conviction score and the expected cost of RFS against the best algo in basis points.

Prototype the arguments, not just the screens.

I used Figma and Axure to model the key interactions, so competing ideas could be compared in a working prototype instead of a meeting room. Stakeholders could see their thinking in context and agree on what worked best.

A complex idea, made usable.
