I built a B2B lead generation app. You type in an industry and a location, and it finds real businesses through the Google Places API, then enriches them with company data and decision-maker emails via Apollo. Every email gets validated, and GPT-4o-mini writes a short personalized pitch plus a lead score for each lead. One click exports everything to CSV or Excel.
The three API keys are yours. You enter them once in the setup wizard and they stay encrypted on your own machine. Nothing is scraped, no proxies, no LinkedIn tricks, no SMTP probing. The app tells you exactly what each run costs in Google API fees before you spend it, filters out bad-fit leads before any paid enrichment runs, and picks up cleanly if the server restarts halfway.
It ships as a one-click Windows installer and a Docker image. React on the frontend, FastAPI on the backend, JWT auth, and 14 tests green.

Automated B2B Lead Gen Engine from LinkedIn Jobs (n8n + Apify + Apollo + Gemini)
Project Overview
Hiring intent is the highest-converting B2B buying signal. When a company posts an open role on LinkedIn, they have an active pain point, immediate budget, and executive mandate to solve that problem.
This automated production engine runs every morning without manual intervention. It scrapes fresh LinkedIn job postings via Apify, filters out non-target companies, queries Apollo.io to identify the exact decision-maker (Founder, CEO, VP, or Head of Department) with their verified work email, and uses Google Gemini to write hyper-personalized outbound pitch drafts directly into Google Sheets.
Visual Showcase & Live Architecture
1. Verified Leads Database & AI Outbound Drafts (Google Sheets)
Preview unavailable
Automated output storing company data, verified decision-maker email, LinkedIn profile URL, hiring intent triggers, and ready-to-send AI cold email copy.
2. End-to-End n8n Engine Blueprint
Preview unavailable
Full production pipeline orchestrating Apify actor execution, domain validation, Apollo personnel search, Gemini structured output parsing, and real-time sheet sync.
Technical Workflow Architecture
Targeted Job Extraction (Apify): Triggers an automated actor scraping LinkedIn job postings based on target titles, geographic focus, and date posted.
Data Sanitization & Strict Gatekeeping: Filters dataset entries by company size (< 250 headcount), eliminates recruitment agencies and HR service providers, and verifies live web domain resolution.
Personnel Enrichment & Email Validation (Apollo.io): Targets executive personas matching the hiring team, executes verification checks against corporate MX records, and retrieves direct work emails and LinkedIn URLs.
Context-Aware Email Drafting (Google Gemini): Analyzes job descriptions, extracts company pain points, and drafts personalized 3-sentence email openers with high deliverability scores.
Centralized Data Lake (Google Sheets / CRM Sync): Logs verified contact records, generated copy, and campaign statuses, ready for direct one-click import into Smartlead, Instantly, or Clay.
Key Performance Metrics
Runtime Execution: 2 minutes per batch run (50–100 validated leads).
Email Deliverability: 98%+ valid deliverability via Apollo API verification.
Workflow Efficiency: Replaces 10–15 hours per week of manual SDR prospecting.
Data Quality: 100% deduplicated against previous pipeline runs.
Deliverables Included
Complete standalone n8n workflow JSON blueprint ready for self-hosted or n8n cloud instances.
Pre-configured Apify scraper actor setup and Apollo.io API integration.
