John Lewis · Product Design Leadership

Turning complexity into clarity.

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

The work is clarity: for customers, teams, and business decisions.

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

Make the bet clear before features take over.

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

Make quality easier to repeat.

Builds critique quality, role expectations, and operating rhythms that make strong design judgment repeatable across teams instead of dependent on heroics.

Research

Turn noisy signals into product direction.

Uses research as decision fuel: synthesizing customer behavior, evaluative findings, and product signals into roadmap-shaping choices.

Complex Systems

Make systems easier to trust.

Transfers well to emerging product spaces because the work centers on ambiguous behavior, system trust, feedback loops, and product decisions under uncertainty.

Execution

Use craft to make behavior clearer.

Treats interaction quality, reward design, and feedback states as business levers, not decorative polish layered on after direction is set.

Measurement

Make impact easier to see.

Uses experimentation, operator metrics, loyalty behavior, and commercial results to keep design tied to measurable business performance.

Leadership Scope

The role scaled through people, standards, and decision forums.

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

I’m most useful when design has to make the work clearer.

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

Frame the decision before the solution

Help teams understand the customer behavior, business stakes, and product choices that should guide the work.

Ecosystems

Connect the parts customers feel

Bring loyalty, rewards, research, operations, and platform decisions into more coherent product experiences.

Teams

Make quality scale through people

Build standards, rituals, and manager systems so strong design judgment is not dependent on one person.

Design Impact

Initiative results measured alongside design decisions across revenue, engagement, operator speed, and platform scale.

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.

+9% GGR

Initiative

Rewards Club A/B Test

The four-month U.S. A/B test measured GGR, active-player days, and generosity perception together as part of the Rewards Club readout.

+18% higher NGR

Initiative

Bonus Draw customers recorded higher NGR and eGGR than control, making reward format a concrete variable for the team to compare.

69% fewer CS contacts

Initiative

Bonus Spins Merch

+363% daily active players

Initiative

0 bugs + same TTM

Initiative

Canada Parity

The Canada launch recorded zero bugs; equivalent post-launch features matched U.S. time to market and QA time per release was lower.

Rewards Club / Loyalty

A/B and rollout comparisons track active-player days, GGR, generosity perception, tier progression, CRM opens, and retention by initiative and period.

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

Six stories with six different proof jobs.

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

How I turn complexity into clarity across strategy, teams, and outcomes.

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.
