## Executive profile

Stephanie's strongest work turns ambiguity into a coherent product model, then carries that model through the system—from architecture, behavior, and defaults to controls, explanations, and measurable outcomes. She is especially effective in early product spaces where the interface cannot be separated from model behavior, context, memory, permissions, intervention, recovery, and observability.

Her range is unusually broad: she has reframed product strategy, designed dense enterprise workflows, created a user-facing design system, solo built a production agent, dogfooded real outbound campaigns, prototyped physical hardware, and coded independent mobile products.

## Experience

- Seam AI — Founding product designer. Seam AI was acquired by Clarify. Stephanie worked across product strategy, AI behavior, agent infrastructure, interaction design, and production implementation.
- Sigma Computing — Product designer for data-heavy workbook experiences and Sigma's first user-facing design system.
- Tulip Interfaces — Product designer for enterprise administration and frontline mobile tools.
- Samsung Research — Interaction designer for a virtual human healthcare assistant created with Aramark Healthcare.
- Independent — Product builder working across mobile software, physical computing, AI, and creative tools.

## Distinctive strengths

- Agent-native product design: treats model behavior, context, memory, permissions, intervention, recovery, and observability as design materials.
- Systems thinking: turns disconnected capabilities into clear mental models and end-to-end product journeys.
- Design-to-production range: can move from framing and interaction design into prompts, skills, architecture, prototypes, code, and dogfooding.
- Trust and explainability: makes reasoning visible, preserves meaningful user control, and avoids false precision.
- Enterprise rigor: designs for governance, determinism, multiple user roles, dense data, and operational constraints.
- Progressive disclosure: keeps simple paths approachable while preserving auditability and power-user depth.
- Editorial clarity: combines fine-art instincts for composition and restraint with a journalism-informed ability to find the story in messy information.

## Verified outcomes

- Agent Stitch drove approximately $300K in sales pipeline during the demo stage.
- Seam workflow-orchestration work reduced sales demos from about two hours to under 30 minutes and contributed to growth beyond $500K ARR.
- Fit Score reached 100% adoption across all paying organizations and about 80% of total credit usage; competitors copied the approach within months of its September 2025 launch.
- Sigma's remove-duplicates workflow reduced clicks by 92% and completion time by 84% for a problem reported by more than 32 customer organizations.
- Stephanie solo designed and shipped the Agent Stitch production app in roughly one week using AI coding tools.
- Tulip's native iOS experience was delivered in one month and earned five-star App Store reviews.

## Seam AI — selected work

- [Workflow orchestration](https://stphw.me/workflow-orchestration): Reframed four disconnected tools—TAM Builder, Qualifier, Prospector, and Enrichment—as an opinionated, template-first orchestration system. Designed guided setup, progressive configuration, and an observable agent trace. Sales demos fell from about two hours to under 30 minutes; the clearer story contributed to growth beyond $500K ARR.
- [Agent Stitch](https://stphw.me/stitch): Solo designed and built Seam's autonomous ABM agent on Claude Managed Agents across system prompt, per-tenant memory, skills, managed sessions, architecture, and a focused non-chat interface. Designed layered control, learning through normal UI edits, state-based workflows, and progressive disclosure. Shipped the production app in roughly one week and drove approximately $300K in sales pipeline during the demo stage.
- [Fit score agent](https://stphw.me/fit-score-agent): Designed customizable AI account scoring around open-text criteria, visible reasoning, meaningful A–D grades, and backtesting. Reached 100% adoption across paying organizations and about 80% of total credit usage.
- ABM stages and intelligence layer: Visualized scoring, intent, and decision-making atop Seam's data model so AI behavior became visible, actionable, and trustworthy. See the portfolio home for the external project link.

## Sigma Computing — selected work

- [Sigma's first user-facing design system](https://stphw.me/sigma-design-system): Created a system that let data analysts build accessible, user-friendly data apps directly in Sigma workbooks. Includes colors, controls, themes, and data-element patterns.
- [Workbook exploration](https://stphw.me/workbook-exploration): Designed the entry point, configuration, and deterministic result for removing duplicate rows. Followed user mental models while hiding product-specific grouping machinery, not meaningful user control. Reduced clicks by 92% and completion time by 84%.

## Tulip Interfaces — selected work

- [Admin dashboard](https://stphw.me/admin-dashboard): Designed an extensible account overview for executives and administrators during Tulip's move to usage-based pricing, making usage, account health, and next actions legible.
- [iOS app](https://stphw.me/ios-app): Redesigned Tulip Player as a native, glove-friendly mobile experience for frontline workers. Delivered in one month and earned five-star App Store reviews.

## Samsung Research — selected work

- [Neon Assist for healthcare](https://stphw.me/neon-assist): Designed a virtual human assistant that simplified hospital meal ordering in partnership with Aramark Healthcare, with a focus on conversational trust and recovery in a high-stress context.

## Independent work

- [Palette Plate](https://stphw.me/palette-plate): Designed and coded an experimental AI-assisted kitchen tool using a Raspberry Pi, projector, and camera to guide creative plating.
- [Chromia](https://chromia.framer.website/): Designed and coded an iOS app for noticing color, privately archiving it, and exchanging color postcards with strangers.
- [Be water, my friend](https://stphw.me/be-water): Personal essay about energy, ambition, adaptation, and learning to be like water.

## Design philosophy

Stephanie believes the interface in an agentic product is not only the screen. It includes the model behavior, the context it sees, the memory it keeps, the assumptions it makes, the moments it asks for help, how it recovers, and how it returns control under uncertainty. She is drawn to dense systems and early, ambiguous product spaces where design can define a new capability rather than simply polish an existing one.
