ActNow

A volunteer matching platform: helpers swipe through volunteering opportunities near them, and non-profit organisations publish offers, review applications and chat with helpers.

Try the interactive demo (also on Hugging Face Spaces): no sign-up needed. Switch between the helper view (Anna) and the organisation view (SV Sonnenschein) in the top bar. The demo runs on fictional data and saves nothing.

Helper view: discover and swipe	Organisation view: dashboard

The interface is in German, since the platform targets volunteers in Germany.

The problem

Non-profits need helpers on short notice. People who want to volunteer often don't know which organisations near them need help. ActNow brings both sides together: offers by place and time, applications and messaging in one app, and mutual ratings to build trust. Full problem statement: docs/problem-statement.md.

Features

For helpers: swipe-based discovery, applications, calendar, favourites, community, profile. For organisations: dashboard, offer management, application review, messaging, organisation profile.

Architecture

The product was built as a full-stack app on SvelteKit and Supabase (Postgres, Row Level Security, Realtime, Storage). For the public portfolio version the frontend runs as a static, read-only demo: a local DemoRepository serves fictional fixtures, and write actions show a notice instead of changing data. No backend, login or cookies are involved.

Visitor → GitHub Pages → static SvelteKit SPA → DemoRepository (fixtures, read-only)

The backend work stays in the repo as reference: versioned Supabase migrations, RLS policies and an RLS smoke test suite in supabase/.

Tech stack

SvelteKit 2 · Svelte 5 · TypeScript · Tailwind CSS · Supabase (Postgres, RLS, Realtime) · Playwright · ESLint and Prettier · GitHub Actions and GitHub Pages

Run locally

cd frontend
corepack pnpm install --frozen-lockfile
corepack pnpm dev

Quality gates (the same ones CI runs):

corepack pnpm lint
corepack pnpm check
corepack pnpm exec playwright install chromium
corepack pnpm test:e2e
corepack pnpm build

Team and my role

University team project by Yannik Huber, Dennis Müller and Arian Sharifi-Tabar.

I wrote most of the commits and led the production hardening and the portfolio release:

• Supabase schema as versioned migrations, RLS policies and an RLS smoke test suite
• Supabase services for applications, messages, notifications and saved offers
• tooling and CI: ESLint, Prettier, GitHub Actions, static build
• conversion into the read-only portfolio demo with role switcher and GitHub Pages deployment
