Context
When a pet goes missing, the search starts in the noisiest place.
Today alerts live in Facebook groups, WhatsApp chats, and unstructured posts. Information fragments and cannot be filtered by area, species, or date.
Everything happens on Facebook
Alerts live in groups, chats, and unstructured posts. Information disappears from the feed within minutes.
No shared criteria
Every post follows a different format. It is hard to filter by area, species, date, or the animal's status.
Real urgency
The first hours are critical. Publishing and finding alerts has to be fast, clear, and low-friction.
I was not designing another social network. I was designing an assistant so an urgent alert would not get lost between memes and unrelated posts.

Challenge
The challenge
Build a search assistant that centralizes reports, cuts through social media noise, and helps owners and neighbors coordinate with reliable, actionable information.

Research
Interviews and surveys to understand owners, neighbors, and the current ecosystem.
Research focused on three actors: the pet as the object of the search, the owner in an urgent situation, and the community that wants to help without friction.
Methods
- · In-depth interviews
- · Surveys
- · Social group analysis
The pet
A clear photo, distinguishing marks, and last known location are the first things everyone looks for when scanning an alert.
The owner
Needs to spread the word quickly without repeating the same information across five different groups.
The community
Wants to report a sighting without friction, know if someone already did, and contact discreetly.

Architecture
Site map and user flow to report, search, and contact.
The critical path is reporting a pet: alert type, photo, details, location, review, and publish. The rest of the product revolves around making that path fast and reliable.

Wireframes
Structure before UI: validate hierarchy and steps without visual distractions.

UI Kit
A clear, empathetic system that stays readable under pressure.
Readable sans-serif on mobile, with clear hierarchy between titles, alert metadata, and Lost / Found states.

Reports map
Geographic view to understand matches by area and prioritize nearby searches.
Report a pet
Short flow with photo, essential details, and map location, designed for stressful moments.
Alert profile
Detail page with map, description, contact, and clear actions to coordinate the reunion.
