Design decisions I can defend with data.
Ten years in product design, the last five in iGaming and fintech: payment flows, back-office systems, CRM and mobile. I design hands-on in Figma and in code, and I've built and led design teams of up to nine.
Selected work.
Twelve cases. Each one opens with the outcome, then the context, the problem, the approach, and what I would do differently.
Across the work.
The numbers that moved. Every one of them measured on A/B, on the team's tracked time, or on the calendar.
Ten years, four shifts in responsibility.
Craft
High-load internal platforms. Dense tables, permissions, configuration-heavy workflows. Learned to make complexity readable.
First teams
Design Team Lead. Up to 4 designers across parallel B2B and B2C projects. Quality against speed, every week.
Product depth
Dashboards, retention mechanics, A/B testing on live traffic, payment flows. Moved from how to what and why.
Leading teams & product
Design Team Lead / PM. Grew one team 2 → 5, hired 3. Took over another, 7 → 9. Roadmap and hypotheses alongside design. Design system. AI pipeline in production.
What I take on.
Four areas, one flow. Product questions come first, design carries them, the team holds the bar, and the organisation gets what actually ships.
- Reading product metrics to find problems, not waiting for briefs
- Forming and testing hypotheses on live traffic
- Writing specs: the BA work, when there's no BA
- Roadmap input and prioritisation
- A/B testing, deciding from behavioural results
- Design systems from zero: components, libraries, governance
- Back-office, CRM, dashboards, payments
- Optimising handoff so engineers ship faster
- UX debt: finding it, sizing it, clearing it
- Hiring, onboarding, and letting people go
- Grading systems and career paths
- 1:1s, reviews, and the standards that hold the bar
- One flow, not five
- Evaluating and rolling out new tooling
- Compliance: shipping products that hold up in regulated markets
- Ops, automation, engineering, marketing, legal, HR
- Automating team workflows
- AI pipelines in production
