Selected Work
Fifteen years of method.
Each project below began with a problem that resisted simple framing. The work is documented as it happened: the constraints, the decisions, and the outcomes.
A vision for a market data platform
A platform vision that defined three years of product work. Its central idea, one page bringing a market’s prices, news and analysis together, entered live rollout in 2026.
Vision pitched July 2022 · Early pivot to Topics · Seeded a 3-year programme
Read case study →Nadex Mobile PWA
When Apple and Google removed binary options apps from their stores, Nadex lost its mobile distribution overnight, with half of all trading happening on mobile. A Progressive Web App restored access through the browser, but the harder problems sat in the verification flows. A research-led fix to the identity step, where 8% of rejections came from data the user had supplied months earlier, cut document rejections by 42%.
Session engagement: +73% · Order errors: −25% · App Store rating: 4.2★
Read case study →Nadex New Web Platform
Six months after the Nadex mobile PWA launched, the company retired its 11-year-old desktop trading platform. Designing the replacement was not a matter of translating the mobile experience to a larger screen, but of asking what would genuinely be better on desktop. The work held to one constraint throughout: extending the PWA without fragmenting the experience for clients who moved between the two.

Read case study →Account and Payment Improvements
Payment queries accounted for 17% of all contacts to IG’s Trading Services team, a figure that had built up for years without being owned as a design problem. I treated discovery as a project in its own right, building the evidence base needed to win C-level investment before any design began. The systematic redesign that followed lifted bank verification from 35% to 76% and cut related support contacts by 54%.
Bank verification: 35% → 76% · Customer service contacts: −54%
Read case study →Conversion Funnel and Sign-Up Flow
IG Group’s sign-up journey had grown by accretion rather than design, with applicants dropping off at predictable friction points and an Application Result Page that had accumulated 46 variations. Over a two-year programme I rebuilt the flow around what each step was actually for, consolidating those 46 variations into three clear actions. Applicant numbers rose 70% and first-trade conversion more than doubled, from 21.3% to 47.7%.
Completion rate: +65% · Time to complete: −47% · First-attempt success: 91%

Every engagement begins with a question, not a solution.
The methods documented across these six projects are not a skills list. They are a record of what the work required: affinity mapping, heuristic evaluation, Design Sprint facilitation, IBM Hills, Red Routes prioritisation, Lean UX, Dual-Track Design, and stakeholder alignment at C-level.
