ACY Securities

One design system. 5 live platforms. Eight regulatory updates. Zero structural reworks.

Lead designer across five product lines at an ASIC-regulated broker, working directly with the CEO, CFO, Legal, and three engineering teams. I built a 150+ component system where teams ship without coming back to me for every edge case — and it has absorbed 8 regulatory changes at 3–5 days each, against the 3–4 week rebuilds that came before.

Built for durability: the system survived 8 regulatory updates, 3 engineering-team changes, and expansion to 40+ countries — the return on designing for governance, not aesthetics.

Christie's Real Estate

Editorial Platform — I handled design, development, and product decisions

Sole designer and product owner for Christie's International Real Estate editorial platform — 9 months, five global offices, $5M–$80M property buyers. I handled design, development, and stakeholder coordination end-to-end. The challenge: translating 260 years of print brand standards into a digital product without compromising a single weight, colour, or whitespace ratio.

ACY Connect

FIX 4.4 documentation for institutional clients — where a misconfigured message is a million-dollar position sizing error

Designed the documentation and onboarding system for ACY's institutional FIX 4.4 API — the protocol that connects prime brokers, liquidity providers, and institutional clients. Five different types of users (from product managers to market data engineers) all need to understand the same system differently. I designed that experience. This work later became the foundation for TradeX.

The target: self-serve integration — a hedge-fund engineer goes from first API key to production order flow without a support ticket. Integration time fell from 3 weeks to 1 week; support tickets dropped 67%.

Finlogix

Real-Time Market Analytics · Modular Widget System · ASIC Regulated

Trading analytics platform handling 1,000+ real-time data points. I designed a modular widget system so traders could arrange their workspace the way they actually think — not the way a product manager assumed they should. Tested with 15 active traders in controlled sessions. Order placement went from 8.2 seconds to 2.9 seconds. 67% built custom layouts within 3 months (platform analytics, Q4 2023).

The research behind it: a paired within-subjects test (n=15) confirmed the 8.2s→2.9s gain was real, not noise (p<0.001). The more useful finding was which steps caused the delay — confirmation modal and instrument search — and that drove the redesign, not the headline number.
