I need a small-footprint, browser-based application that continuously scans every U.S. Facebook Marketplace listing and pulls the data into a single, searchable interface. I plan to build the front end around React with TypeScript, so your work will slot straight into that stack. Core features I’m after: • Robust search filters so I can zero-in on items, keywords, price ranges, zip codes, or categories on the fly. • Real-time or near-real-time alerts the moment a matching listing appears (think push notification or email webhook). • One-click export of any search result set as a clean JSON file. Behind the scenes the scraper needs to handle high volume without triggering Facebook rate limits or captchas, and the code should be organized so API keys or rotating proxies can be swapped in easily later. If you have a proven approach to headless browsing, HTML parsing, or unofficial Graph endpoints, tell me—in short, I’m looking for something resilient that can run unattended. You’ll hand back: 1. Source code (React + TypeScript front end, scraping/back-end service, and any helper scripts). 2. A short README with setup instructions and environment variables. 3. Demo credentials or video walkthrough proving the live scan, filter, alert, and JSON export all work. If you’re a U.S.-based developer with solid web-scraping chops and you’re comfortable shipping production-ready React/TypeScript code, let’s talk timelines and milestones.

Hi there, I will build the scraping backend and React/TypeScript front end for scanning U.S. Facebook Marketplace listings with keyword, price, zip code, and category filters, real-time alerts via push or email webhook, and one-click JSON export. For resilience against rate limits and captchas, I will rotate requests across multiple headless browser sessions with randomized timing and fingerprint variation, with the proxy layer abstracted so you can swap providers through environment variables without code changes. Questions: 1) How frequently should scans run (every few minutes, hourly), and across how many zip codes simultaneously? 2) For alerts, do you prefer WebSocket push in the browser, email via SendGrid, or both? Send me a message and we can go over the details. Best regards, Kamran

Hi, This is Elias from Miami. I checked your project description and understand you’re looking to develop a browser-based application that continuously scans Facebook Marketplace listings across the U.S. for specific information. I’ve worked on several web scraping projects and understand the key technical challenges involved, especially regarding data accuracy and platform limitations. I would approach this by utilizing JavaScript and Python to handle the scraping efficiently, while ensuring that the app remains lightweight and user-friendly. I have a few questions to get a better understanding: Q1 – What specific data points are you looking to extract from the Facebook Marketplace listings? Q2 – Are there any specific user roles or access levels you want to implement for the application? Q3 – Do you have any existing systems or APIs that this application needs to integrate with? Looking forward to hearing from you.

Hi I can build a React + TypeScript monitoring interface with advanced search, alerts, and JSON export, but I should be transparent that I cannot support bypassing Facebook protections, captchas, rate limits, or unofficial/private endpoints. The core technical risk in this project is not the UI layer, but creating an unattended ingestion pipeline that stays stable, lawful, and maintainable as the source platform changes. My solution would be to architect a compliant data-collection service with modular source adapters, queue-based alert processing, filterable indexing, and export-ready JSON output that fits directly into your React/TypeScript stack. I can structure the backend so notification channels, proxy settings, and provider integrations remain configurable through environment variables and clean service boundaries. On the frontend, I’d deliver a fast searchable interface with keyword, category, price, and location filtering plus one-click exports. I’d also provide clean documentation, setup steps, and a demo workflow showing scan, filter, alert, and export behavior. My strength here is production-ready TypeScript architecture, resilient data pipelines, and maintainable full-stack delivery rather than brittle one-off scripts. Thanks, Hercules
