John Lewis · Product Design Leadership
I lead design where customer behavior, business performance, and cross-functional execution have to line up before teams can move.
At FanDuel, that meant turning loyalty, rewards, promotions, and research into clearer systems for growth, engagement, and decision-making.
I’m strongest where design moves upstream: clarifying the problem, shaping product strategy, and helping teams make better decisions before screens are made.

Leadership Snapshot
My throughline is turning messy product environments into shared direction. That shows up across loyalty, reward mechanics, operator workflows, research, emerging product questions, and team development in places where design decisions affect business performance.
Business Strategy
Most valuable when the work is ambiguous, the stakes are commercial, and the team needs a sharper point of view on what matters first.
Teams
Builds critique quality, role expectations, and operating rhythms that make strong design judgment repeatable across teams instead of dependent on heroics.
Research
Uses research as decision fuel: synthesizing customer behavior, evaluative findings, and product signals into roadmap-shaping choices.
Complex Systems
Transfers well to emerging product spaces because the work centers on ambiguous behavior, system trust, feedback loops, and product decisions under uncertainty.
Execution
Treats interaction quality, reward design, and feedback states as business levers, not decorative polish layered on after direction is set.
Measurement
Uses experimentation, operator metrics, loyalty behavior, and commercial results to keep design tied to measurable business performance.
Leadership Scope
A concise view of the organizational scope behind the case studies: team growth, direct management, career progression, manager development, hiring, and executive-facing decisions.

Where I Create Value
The best fit is commercially important work where customer behavior, business stakes, and cross-functional complexity need to be understood before execution takes over.
Product bets
Help teams understand the customer behavior, business stakes, and product choices that should guide the work.
Ecosystems
Bring loyalty, rewards, research, operations, and platform decisions into more coherent product experiences.
Teams
Build standards, rituals, and manager systems so strong design judgment is not dependent on one person.
Design Impact
The strongest signal is not polish alone. Initiative-level measures were reviewed alongside product and design decisions to compare customer value, support demand, operator velocity, and market portability, then inform priorities.

Reward Machine / Gamified Rewards
Bonus Draw, promotions-as-rewards, branded retention, and new-user comparisons keep each Reward Machine result attached to a named mechanic and cohort.
Bonus Spins / Promotions Mechanics
Reward-format, merchandising, campaign, and game-launch comparisons report conversion, usage, engagement, or support results within their measured contexts.
Operator Experience / Operational Efficiency
Workflow initiatives report time saved, testing-cycle changes, campaign setup time, and support demand for the operators and teams involved.
Platform / Infrastructure / Design Systems
Platform initiatives report launch quality, QA time, reporting scope, tax savings, and budget allocation at the initiative level.
Featured Case Studies
Start with Generosity as the flagship, then compare product coherence, organizational scale, commercial portfolio leadership, research decision quality, and motion as experience quality.
Leadership Operating Model
The strongest leadership work makes hard decisions easier to frame, align around, and measure. Direction, delivery, team development, and business outcomes have to reinforce one another.
Leadership throughline
Turn ambiguity into a system teams can execute and the business can measure.
The goal is not to optimize one moment at a time. It is to create a model where strategy, research, craft, and organizational clarity reinforce one another until better outcomes become easier to repeat.
