Node.js Developer — Smartlead + Claude AI Integration with Analytics Dashboard - Contract to Hire

What is this project?

We run influencer outreach campaigns through Smartlead — a cold email platform. We're reaching out to 700,000+ influencers across 165 countries.

Right now, every reply is handled manually. We want to change that.

We need a developer to build a backend system that automatically reads every reply, understands what the influencer wants, responds intelligently using AI, and tracks everything in a live dashboard — so our team sees the full picture in real time.

The AI brain behind this is Anthropic's Claude (Opus model).

What the system needs to do

1. Before sending an email

When Smartlead is about to send an email — the system asks Claude to write a personalized opening line for that specific influencer (based on their niche, country, follower count). This gets inserted into the email automatically.

2. When an influencer replies

The system reads their reply and Claude decides:

Are they interested? (HOT / WARM)

Do they have a question?

Are they objecting?

Do they want to unsubscribe?

What should happen next?

Then it generates a reply in their native language and sends it back through Smartlead — automatically, within seconds.

3. Follow-up emails

If an influencer hasn't responded, the system generates a smart follow-up based on the conversation history.

4. Weekly strategy report

Every Sunday, Claude analyses all campaign data and sends a report: what's working, what's not, which countries and niches are performing best.

5. Hot lead alerts

The moment Claude detects a highly interested influencer — our team member receives an instant Telegram message with full details.

Analytics Dashboard

Total replies today / this week / all time

Breakdown: how many HOT, WARM, questions, objections, unsubscribes

Top performing countries and niches

Average sentiment score over time
