Trust without a long sign-up

Nina.care matches families with nannies, babysitters and au pairs. I redesigned caregiver onboarding and the family booking flow, where both sides have to trust a stranger before anyone books.

01 — Problem

Families need detail. Caregivers need to finish.

Before a family books a stranger, they want experience, references, health and a face. Every one of those is another step for the caregiver. The audit found weak hierarchy, inconsistent patterns and a flow that didn't guide people through.

Before the redesign: a caregiver and a parent

2 · So many questionsHealth questions? References? Why all this?Fixed by Decision 03

3 · LaterI've lost count of the steps. I'll finish later.Fixed by Decision 02 · the checklist

4 · A parent needs helpI need someone Monday, Tuesday and Friday.Fixed by Decision 04 · booking by shift

6 · No bookingI can't leave my kids with a stranger.Result

Composite story from the audit and research. Panels 1–3: a caregiver. Panels 4–6: a parent. Illustrative. [CONFIRM: matches what research showed]

Before: five booking screens from the usability audit, with weak hierarchy and inconsistent patterns.

Before: five screens with weak hierarchy and inconsistent patterns.

02 — Decision

Short steps, one theme each.

Onboarding became short steps with one theme each, a checklist to come back to, and the same flow on desktop.

What I decided not to do

[NEED: a step or question you cut]

Caregiver onboarding: one theme per step (experience, education, health, references) with yes/no answers.

Caregiver onboarding: one theme per step, yes/no wherever possible, and a checklist to come back to.

Go deeper — Caregiver onboarding in short, themed steps

1. One theme per step. Experience with children and age groups; education, driving licence and first aid; languages; health; references; a short bio with a photo and intro video.

2. Yes/no before free text. Most questions are a toggle; a text field asks for detail where it's needed. [CONFIRM: text fields only appear after a "yes"]

3. A checklist to come back to. "Complete your profile · Tell us about yourself · Preferences — 2 of 3 completed" on the home screen.

4. Same steps on the web. Nationality, country to live and work in, languages and proficiency.

Desktop onboarding: country, nationality, gender and languages as tappable choices.

The same steps on the web.

Signal: [VERIFY: +31% onboarding completion; 89% found their profile easier to complete (S42)]

03 — Decision

Sensitive questions explain themselves before they ask.

The health step says why it's there: to keep everyone safe. [CONFIRM: you considered dropping it, and what kept it in]

What I decided not to do

[CONFIRM: making health questions optional, or removing them]

Health step in caregiver onboarding: yes/no questions, with a note on why they are asked.

The health step: the reason comes before the question.

04 — Decision

Families book by shift, and a "no" comes with a reason.

Families post a request, invite caregivers and approve them shift by shift. Declining asks for a reason, which the caregiver sees. [CONFIRM: why — keeping caregivers on the platform after a "no"]

What I decided not to do

[NEED]

Family booking: requests with a status, a shift calendar, invited babysitters, approve per shift, and a decline with a reason.

Booking and decline: approve or decline each shift; a decline carries a reason.

Go deeper — Booking by shift, from both sides

1. Requests with a status. A family's booking requests show as Open, Matched or Canceled, with shifts, rate and location.

2. A calendar per request. Each shift is marked matched, open or canceled.

3. Review a caregiver per shift. Profile, reviews and a motivational letter, then approve or decline the specific shifts they applied for.

4. Find work that fits. Discover shows requests as cards with area, rate, children and shifts, filtered by days, distance, rate, number of kids, skills and language. [CONFIRM: this is the caregiver view]

Signal: [VERIFY: 87% found search easier and 72% found booking easier (S42)]

05 — Result

Onboarding completion rose 31%.

89% found it easier to complete their profile, 87% to search, 72% to book. [VERIFY: method, sample size, baseline, time window]
