LeadMiner Pro: AI-Powered Local Business Lead Generation & Outreach Platform
Client Context
An internal product developed to demonstrate end-to-end SaaS architecture — from data scraping and AI enrichment to CRM-style pipeline management and direct outreach — showcasing production-grade patterns for lead generation platforms.
The Business Challenge
The core challenge was building a system that unifies three typically separate workflows — lead discovery, lead enrichment, and outreach — into a single, cohesive platform. This required orchestrating external APIs (Firecrawl for scraping, Resend for email), designing a flexible data model that accommodates varying data completeness, and implementing bulk operations (pain point mining across hundreds of leads) without degrading the user experience.
The Bottlenecks (Before)
- Manual searching across multiple directories to find local business contacts
- No structured way to identify customer pain points for personalized outreach
- Disconnected tools for lead storage, email sending, and pipeline tracking
- No centralized system to manage Instagram-based social prospecting
- Exporting and sharing lead data required copy-pasting across spreadsheets
The Solution (After)
- Automated business discovery via keyword + city search with Firecrawl-powered scraping
- AI-driven pain point extraction from customer reviews for personalization at scale
- Unified platform combining lead database, email outreach, and Kanban pipeline
- Built-in Instagram hashtag search for social media lead extraction
- One-click CSV exports with multiple filtering modes for CRM integration
Engineering the Solution
We architected a modular system using Supabase Edge Functions as an API orchestration layer. Each capability — search, mining, email, Instagram — runs as an isolated serverless function with its own error handling. The frontend uses TanStack Query for cache-aware data fetching with optimistic updates, ensuring the UI stays responsive during bulk operations. A progress-tracking system provides real-time feedback during pain point mining across large lead sets. The collapsible sidebar navigation and responsive layout ensure usability across desktop and mobile.
