Muzzy Lin

I design the steps that help people find value, get started, and keep going.

I work on activation and product adoption across SaaS, payments, and AI. I partner with founders and product teams to set priorities, test ideas, and ship with engineering.

Selected evidence

From friction to progress.

YedooAn AI reading companion, designed and built from scratch.iOS launchin one month
Yedoo reading companion and AI book chat

I owned strategy, UX/UI, the design system, and the build. Reading comes first; AI questions stay beside the source passage instead of interrupting it.

Launched on iOS. Designs also cover macOS, iPadOS, and web.

Yedoo case study
Keap PayHelp merchants move to a new payment provider with confidence.70%migrated on time
Keap Pay payment dashboard and onboarding

As sole designer, I led onboarding, migration, and reporting within a five-month deadline. Research and testing helped us clarify verification, remove repeated entry, and show where the money was.

The system processed $70M+ in its first quarter. Launch outcomes reflect the whole team's work.

AI Email HealthTurn a warning into an understandable next step.6 interviewsR&D / not shipped
AI Email Health diagnostic dashboard

I used interviews and a cross-functional workshop to redesign the widget, report, and assistant concepts. The proposed experience connects email-health signals to an action users can take inside their CRM.

A research sprint, not a launch. Recommendation accuracy, user trust, and resolution still need validation.

Email Health case study
AI Strategic PlanningMake agent permissions and human review explicit.Independentconcept redesign
AI strategic planning with agent change review

I redesigned an early concept around separate monitoring and analysis roles. Suggested changes remain drafts until a person reviews them.

A separate exploration because my original work is confidential. Not the client product, a shipped solution, or a validated result.

Strategic AI exploration
Amplift AIBring useful AI opportunities onto the home screen.3× fastercampaign setup
Amplift AI ranked marketing opportunities

People left home to find Opportunities. I brought suggestions into their starting point, helping them move from discovery to a first campaign.

The case reports 3× faster setup and 60% research time saved in a post-launch survey. Measurement context is included in the case.

Invoice TemplatesMake repeat billing easier to start and reuse.20% adoptionin the first three months
Keap reusable invoice templates

I designed visual previews, ownership, and pricing details so businesses could reuse invoices without rebuilding them. Six-user testing refined selection, saving, and reuse.

Reported outcomes also include 75% faster creation and 42% fewer billing-related support requests. Measurement limitations are noted in the case.

Invoice Templates case study
ServiceNowOne entry point for everyday employee questions.12.5Kemployees served
ServiceNow employee benefits and support portal

I worked on research, information architecture, flows, and prototype validation for a unified employee portal.

The case reports 85% self-service resolution. This was an employee-experience project, not a customer-acquisition funnel.

ServiceNow case study

Some projects are under NDA. Each case identifies reconstructed visuals, independent explorations, and limits to the available evidence.
