Project description:
"Job Title: API Developer for Google Ads Click Fraud Detection & Keyword Automation Platform
Location: Remote
Job Type: Contract / Freelance (with potential for long-term collaboration)
Start Date: ASAP

Project Overview:
We are building a web-based SaaS platform that integrates with Google Ads via API to help advertisers reduce wasted ad spend and automate campaign optimization. The system will offer two main features:

Click fraud detection and IP blocking

Automated negative keyword management

Additionally, the platform must support user account creation, reporting, and automated billing.

Core Responsibilities:
1. Click Fraud Detection
Monitor website visitors and track IP addresses.

Apply behavioral rules to identify fraudulent clicks (e.g., bounce in <0.3 sec, 2–4 visits/day).

When fraud is detected:

Automatically exclude the IP in Google Ads via API

Send real-time SMS alerts when daily spend exceeds a preset threshold

2. Negative Keyword Automation
Analyze search terms reports from Google Ads.

Extract irrelevant keywords based on rules (e.g., when bidding on "Bob Hats", exclude terms like “my,” “for,” “cat” from “hat for my cat bob”).

Automatically add negative keywords via API to prevent similar future queries.

3. User Sign-Up, Reporting & Billing
Develop a user registration and login system (with email verification).

Integrate a subscription-based billing system (e.g., Stripe or similar) to manage paid plans and auto-renewals.

Users should receive:

Access to a personal dashboard

Daily or weekly click fraud/keyword reports

Notifications and account usage stats

Tech Requirements:
Google Ads API (essential)

Web development (Node.js, Python, or similar frameworks)

Frontend (React, Vue, or similar preferred)

Database (MySQL, PostgreSQL, MongoDB, etc.)

Twilio (or similar) for SMS integration

Stripe or another billing platform for SaaS monetization

Hosting (e.g., AWS, DigitalOcean, or Firebase)

Nice to Have:
Experience building marketing or ad tech tools

Familiarity with Google Analytics or other visitor tracking systems

Ability to implement multi-tenant architecture for scaling
