Experience

Design engineering leadership across an operator-and-founder career. Outcomes are quantified where they can be.

Hi MarleyDirector of Product Design2025 — presentInsurtech · Series B
  • Established a three-tier design fidelity model (production code, Figma overlays, and an interactive Vercel prototype site) chosen by intent rather than default. Replaced single-fidelity handoffs with a system where each tier earns its use.
  • Consolidated four legacy component libraries into one production design system used by every product surface.
  • Embedded design in engineering workflow by shipping production code alongside the team, not handoffs.
HypothFounder2025 — present
  • Founded a studio framed as a sequence of hypothesis-led experiments. The pattern: write the question first, ship narrow, publish a continuation note or post-mortem either way.
  • Currently running two experiments in beta (Wren) and ideation (Olllo); deferred a third (AI conversational interface, H-04) until v1 of the studio's public properties is locked.
Current experiments: Wren H-02 · in beta, Olllo H-01.
KlaviyoSenior Manager → Director of Product Design2021 — 2025Martech · Series D to IPO
  • Following the VP of Design's departure, held sole design quality authority across the 80-person design organization: the single approver on 160+ design reviews across all product areas, including ventures and AI.
  • Built three design teams from zero (Design Systems, Content Design, Internationalization), growing the group to 16 ICs and 2 managers while the design org expanded from 12 to 80.
  • Founding PM, designer, and systems architect for the Ascent Design System: roughly 1,000 design tokens, 50+ net new components, and 2,203 of ~2,700 legacy form components replaced.
  • Led design strategy for the company-wide internationalization initiative: French shipped in Q2 2024 as the platform's first non-English language, followed by five more languages by Q3 2024.
  • Ran growth experiments, including a free-to-paid conversion test that lifted 28-day conversion +0.7% absolute and went GA.
VertexHead of Design2017 — 2021Pharma · Public
  • Built and led the Experience Design team from zero inside a Fortune 500 biotech.
  • Created the company's first design system, consolidating tooling across biology, chemistry, clinical, and exec knowledge management.
  • Reported to and partnered with C-level on platform consolidation strategy.
