Over the past week I built and shipped a full AI automation stack from scratch. Five tutorial videos live on YouTube, 800+ leads per day automated, 3 AI agents running 24/7 on a $7/month VPS, and a full dental office AI system. Here's the complete breakdown.

The Stack

AI Layer:       Claude (Anthropic) + Groq (llama-3.3-70b) + ElevenLabs TTS
Backend:        Node.js, Python, BullMQ job queues
Server:         IONOS VPS Ubuntu — $7/month, 125GB RAM
Email:          Brevo SMTP — 300 free emails/day
Video:          FFmpeg Ken Burns + ElevenLabs audio
Auth:           Google OAuth 2.0 (saved token — no re-auth ever)
Deploy:         PM2, Nginx, Let's Encrypt SSL

Tutorial 1: I Automated 800 Leads/Day with Python + Claude AI

The lead generation pipeline:

Python scrapes LinkedIn/directories via Playwright stealth
Claude AI scores each lead 1-10 for fit
Personalized cold email generated (Brevo sends 280/day free)
All logged to SQLite — full audit trail

# Core scoring call
response = client.messages.create(
    model="claude-3-haiku-20240307",
    max_tokens=512,
    messages=[{
        "role": "user",
        "content": f"Score this lead 1-10 for AI automation services: {lead_data}"
    }]
)
score = int(response.content[0].text.strip())

Result: 800+ leads scored per day. $0 API cost on Haiku. Watch the full tutorial →

Tutorial 2: 3 AI Agents Running 24/7 for $7/Month

Three autonomous agents on one VPS:

LeadGen Agent — scrapes + scores + emails
Newsletter Agent — curates AI news, sends weekly
CyberSec Agent — scans server, watches for anomalies

All managed by PM2 (process manager) with BullMQ for job queues. Redis as the shared message bus.

# Start all 3 agents
pm2 start ecosystem.config.js
pm2 save
pm2 startup  # Survive reboots

# Monitor
pm2 monit

Total cost: $7/month IONOS VPS. Free Redis. Watch the tutorial →

Tutorial 3: Send 280 Cold Emails/Day FREE — Brevo + Claude AI

Brevo's free tier: 300 emails/day, no credit card required.

from email.mime.text import MIMEText

def send_email(to, subject, body, from_email="outreach@cybercowboys.io"):
    msg = MIMEText(body, 'html')
    msg['Subject'] = subject
    msg['From'] = from_email
    msg['To'] = to

    with smtplib.SMTP_SSL('smtp-relay.brevo.com', 465) as server:
        server.login(BREVO_LOGIN, BREVO_KEY)
        server.send_message(msg)

Claude generates the personalized body. Brevo sends it. Watch →

Tutorial 4: Build an AI Agent in Python — Zero to Deployed in 1 Hour

The MAPE loop pattern I use for every agent:

Monitor: Check for new data/events
Analyze: Claude/Groq evaluates what matters
Plan: Decide what action to take
Execute: Send email, log to DB, trigger webhook

class AIAgent:
    def mape_loop(self):
        while True:
            data = self.monitor()        # Check new leads/events
            analysis = self.analyze(data) # Claude scores
            plan = self.plan(analysis)    # What to do
            self.execute(plan)            # Send, log, alert
            time.sleep(60)               # Run every minute

Tutorial 5: $7/Month VPS — Node.js + PM2 + Nginx + SSL

# Full server setup in 10 commands
apt update && apt install -y nodejs npm nginx certbot python3-certbot-nginx
npm install -g pm2
pm2 start app.js --name my-app
pm2 startup && pm2 save

# Nginx + SSL
certbot --nginx -d yourdomain.com
# Done. Production-ready. Forever.

The Genesis Dental Agent (Bonus Project)

Built a full autonomous dental office AI — 7 BullMQ workers:

Recall Engine — contacts overdue patients
AR Recovery — chases unpaid balances
Morning Huddle — AI briefing at 6am
Treatment Activation — follows up stale treatment plans
Insurance Pre-Auth — flags procedures needing pre-auth
New Patient Onboarding — welcome sequence
MedDental Bridge — queues complex billing to billing agent

All running on the same $7/month server. Same MAPE loop. Groq for fast screening, Claude for deep analysis.
