🤖 n8n automatyzacje (self-hosted, 0 zł)

Platforma wysyła podpisane eventy na webhooki n8n (nowe zlecenie, match, kontrakt, płatność, prowizja referral, dzienny raport AI), a n8n może też tworzyć zlecenia przez POST /api/n8n/trigger. 5 gotowych szablonów w n8n-workflows/ (Telegram, Slack, formularze → zlecenia). Konfiguracja i instrukcje: doku/N8N_AUTOMACJE.md.

Full bilingual (PL/EN) platform blueprint — business model, architecture, audit findings, and all 8 new features in detail: doku/MEGA_PLATFORM_BLUEPRINT.md.

🤖 AI Matching Engine (self-working)

1. Job analysis — Claude API extracts category, skills, urgency, fair price (app/utils/ai.py). Rule-based fallback when no API key → platform works out of the box.
2. Embeddings — OpenAI text-embedding-3-small (1536 dims) with a deterministic local hashing vectorizer fallback. Zero-cost offline mode.
3. Search — pgvector cosine similarity (pgvector/pgvector:pg16 image), automatic Python fallback.
4. Scoring — SCORE = Semantic(0.40) + Rating(0.25) + Price_Fit(0.20) + Availability(0.15).
5. Top 3 matches → auto email + in-app notifications → freelancer accepts → contract.

⚙️ Automation (Celery — runs 24/7)

• matching.trigger_ai_matching — full matching pipeline per job (also runs inline if Celery is down)
• matching.recommend_jobs_to_freelancers — nightly re-matching
• reports.daily_summary — 07:00 daily revenue/activity email to admins
• reports.auto_complete_overdue — auto-closes stale contracts
• Flower dashboard on :5555 to monitor tasks

🚀 Deploy

1. Backend → VPS (30 min)

# Hetzner CAX11 (2 vCPU / 4 GB / 40 GB) ≈ 20 PLN/mies.
ssh root@YOUR_VPS_IP

apt update && apt install -y docker.io docker-compose-v2
git clone <your-repo> /opt/dropify && cd /opt/dropify

cp backend/.env.example backend/.env
nano backend/.env        # SECRET_KEY, ANTHROPIC_API_KEY, OPENAI_API_KEY, SMTP, N8N_*
docker compose up -d --build

# Verify
curl http://localhost:8000/api/health
# Docs: http://YOUR_VPS_IP:8000/docs

# n8n UI (localhost only) — przez SSH tunnel:
#   ssh -L 5678:127.0.0.1:5678 root@YOUR_VPS_IP  →  http://localhost:5678

2. Domain + SSL

# Point DNS A record → VPS IP, then:
apt install -y certbot
certbot certonly --standalone -d api.dropify.app
# Edit nginx.conf: replace dropify.app with your domain
docker compose restart nginx

3. Frontend → Vercel

1. Push repo to GitHub.
2. Import in vercel.com/new.
3. Add env var: NEXT_PUBLIC_API_URL=https://api.dropify.app/api
4. Deploy. Language switcher (PL/EN) is built in.

4. Seed demo data (optional)

docker compose exec api python scripts/seed.py
# Demo login:  [email protected] / demo1234
# Freelancers: foto@, studio@, dev@, design@, [email protected] / demo1234
# Admin:       [email protected] / admin123

Local development

# Backend (needs PostgreSQL+Redis or use docker for infra):
cd backend && python -m venv venv
source venv/bin/activate  # venv\Scripts\activate on Windows
pip install -r requirements.txt
cp .env.example .env
uvicorn app.main:app --reload --port 8000

# Celery (optional): celery -A app.tasks.celery_app.celery_app worker -l info

# Frontend:
cp .env.example .env.local   # NEXT_PUBLIC_API_URL=http://localhost:8000/api
npm install && npm run dev   # http://localhost:3000
