Lead Maps : Google Maps Data Scraper

Overview

Lead Maps is a sophisticated B2B intelligence ecosystem designed to bridge the gap between raw spatial data and actionable lead pipelines. Utilizing a high-concurrency Playwright engine and an asynchronous FastAPI backend, the platform automates the extraction of verified business data from global mapping services. The user experience is prioritized through a stunning, glassmorphism-inspired React dashboard that offers real-time monitoring and advanced data visualization. The platform also integrates high-end security protocols and multi-format export capabilities, ensuring a seamless and professional workflow for high-volume sales operations.

Problem

Sales teams lose significant overhead to manual prospecting and fragmented data collection, leading to stale leads and missed revenue opportunities in a competitive local market.

Solution

Lead Maps delivers an elegant, high-speed automated pipeline that transforms raw map queries into structured, verified lead databases through a secure and elite user interface.

Key Features

  • 1Asynchronous Concurrency via asyncio.gather
  • 2Real-time Lead Stream Visualization (Recharts)
  • 3Secure Numeric OTP Onboarding Pipeline
  • 4Commercial-Grade Password Security (Argon2id)
  • 5Multi-Instance Browser Resource Management
  • 6Granular API Rate Limiting via SlowAPI Middleware
  • 7High-Resolution CRM-Ready Exports (CSV/JSON/Stream)
  • 860FPS Micro-Animations via Framer Motion Orchestration

Challenges & Learnings

Challenges: Perfecting the orchestration of asynchronous Playwright contexts to handle massive concurrency without resource exhaustion; implementing a robust, bot-resistant auth suite; and resolving complex SSL/CORS handshakes across a distributed microservice architecture.

Learnings: Advanced architectural insights into the lifecycle management of long-running background workers and the optimization of high-fidelity React state transitions for real-time dashboards.

Result

A state-of-the-art lead generation platform featuring premium dark-mode aesthetics, fluid glassmorphic UI components, and a measurable 10x increase in prospecting throughput.
