01Overview

Lista Solidária is a full-stack donation platform: people and families publish lists of what they actually need, donors and companies cover an item, part of one or a whole list, and an admin area moderates, verifies and audits everything in between.

02The problem

Asking for help online usually means a loose message and a PIX key. Donors can't see what is still missing or whether the request is real, and whoever runs the campaign has no way to show progress or keep bad actors out.

02The approach

Treat each request as a structured list, not a post: items with priority and urgency, a goal, visible progress and a public location. Put the trust work behind it as first-class product: account types, verification levels, roles and permissions, reports, fraud signals and an audit log of every critical action.

03The build

What was actually built

  1. 01

    A NestJS 11 API with Prisma on PostgreSQL: 29 models across users, profiles, lists, items, contributions, payments, verification, reports and notifications.

  2. 02

    Lists typed by need (education, health and accessibility, housing, technology and more), with items, priority and urgency, and contributions that can cover a full item, part of one, a reservation or an entire list.

  3. 03

    Three account types (donor, beneficiary, company), five verification levels, and roles and permissions for admins, with a super-admin seeded from the environment.

  4. 04

    An admin console in Next.js 16 and React 19: moderation of lists and items, reports, fraud signals, payout blocks and an audit log searchable by action, entity and actor.

04The experience

A school-supplies list for a sixth-grader, with its story, public location, a goal of R$ 640,00 with R$ 338,00 raised, and buttons to help.
A public list: the story, the goal, the progress and what is still missing.
The same list on a phone: R$ 338,00 of R$ 640,00, 53% of the goal, and the sign-in buttons to help.
Helping starts from the list itself, on the phone.
Admin audit page with tabs for panel, operation, fraud, risk, payments and roles, and a table of logins, reports and published lists with entity, actor and date.
Audit: every critical action, filterable by action, entity and actor.
A campaign card on a phone: a notebook for a technical course, 23% of the goal and R$ 600,00 raised.
Explore: campaigns with their category, place and progress.
Admin fraud-signals screen on a phone, with the admin sections as chips below it.
Fraud signals, triaged by severity from the admin area.
