Python Developer for E-Commerce Alert Program

@rinsadsl

Hello, Good Day! I’m interested in your project and can help build a high-performance Python alert system for monitoring newly listed items across the target marketplaces. I have strong experience with Python, API integrations, structured scraping workflows, filtering logic, and real-time notification systems for e-commerce and marketplace monitoring. For a project like this, I would focus on a stable and scalable approach using official endpoints where available, fast scraping pipelines where permitted, efficient request handling, deduplication, keyword filtering, and low-latency alert delivery. The key part is building a reliable detection engine that captures new public listings quickly and consistently without breaking when site structures change. I can also design the system to support proxies, retries, logging, and modular expansion for additional platforms later. I should note that I only build solutions that rely on publicly accessible data and compliant collection methods, not vulnerabilities or unpublished/private listing data. If your goal is fast detection of newly visible listings, I can absolutely help architect that in a robust way. Let’s discuss your alert conditions, delivery method, and preferred deployment setup. Kind Regards, Rinsad

Hello — I’m Iosif, a Python engineer with experience building real-time scraping systems, monitoring pipelines, and low-latency alerting tools. I understand your goal: detect new listings across multiple marketplaces as fast as possible and trigger alerts reliably. Important note: accessing “pre-public” or hidden data via vulnerabilities is not something I support. However, I can build a high-performance system using legitimate methods that achieves near real-time detection (sub-second polling + event-driven updates where possible). Proposed approach • Multi-source ingestion layer — optimized scraping/API calls per platform (Mercari, Bunjang, Yahoo, etc.) • Parallel async architecture (Python asyncio) for sub-second refresh cycles • Smart diff engine — detects new listings instantly without reprocessing all data • Caching + rate optimization to avoid bans while maintaining speed • Alert system — webhook, email, or Telegram for instant notifications • Resilience — retries, proxy support, anti-blocking strategies For platforms with APIs or WebSocket traffic, I’ll use direct endpoints where available to reduce latency significantly. Outcome A stable system that detects new listings within ~1 second (depending on platform limits) and sends alerts immediately. Happy to discuss which platform is highest priority and optimize specifically for it.

I understand you need a Python program that alerts you within 1 second of new items listed on five specific marketplaces. Fast updates like this usually require tapping into less obvious data sources or using techniques beyond standard scraping—like intercepting API calls or leveraging websockets. I’ve handled similar challenges where official APIs lagged behind user views. For instance, I helped a client in retail who needed near-instant product availability alerts by reverse-engineering private API endpoints and efficiently polling only changed data. This cut delays from minutes to under a second. To proceed, I’d first want to explore how fresh data flows on these sites. For example, do the platforms use websockets or have hidden API routes? Would you prefer an always-on process that pushes alerts, or periodic pulls? Also, do you want alerts through email, SMS, or another channel? I’m ready to start investigating immediately and build a robust system to capture truly first-hand data fast and reliably.

@aadips

I can build a Python-based real-time alert system that monitors all 5 Japanese/Korean e-commerce platforms (Mercari, Bunjang, PayPay Fleamarket, Fril, Yahoo Auctions) for new listings with sub-second response times. My approach: • Reverse-engineer API endpoints for real-time data streams (not traditional scraping) • Implement WebSocket connections where available for instant notifications • Use asyncio for concurrent monitoring across all platforms • Deploy headless browser automation (Selenium/Playwright) as fallback • Build notification system (Telegram/email/webhook - your choice) Technical stack: ✓ Python 3.10+ with asyncio for concurrent operations ✓ BeautifulSoup/lxml + requests for efficient data extraction ✓ Playwright for anti-bot bypass if needed ✓ Redis for caching & duplicate detection ✓ Configurable filters (keywords, categories, price ranges, sellers) I've built similar systems for real-time tracking on Amazon, eBay & auction sites. The key to achieving <1s latency is tapping into first-hand data streams before public display. Timeline: 8-10 days Budget: $1,125 USD Questions: 1. Preferred alert method (Telegram bot, email, webhook)? 2. Specific keywords/categories to monitor? Looking forward to delivering a fast, reliable solution!

@SkillCrafts

Having developed several high-frequency price and inventory trackers for major e-commerce platforms, I understand that the primary challenge for an alert program is minimizing latency while bypassing sophisticated bot detection. Recently, I built a custom Python-based monitoring engine that tracked limited-edition drops across multiple Shopify and WooCommerce storefronts, delivering instantaneous push notifications via Discord in under two seconds. I am confident I can deliver a robust, high-performance solution for your project that ensures you are notified the moment new items hit the catalog, giving you a distinct competitive advantage through speed and reliability. My technical approach focuses on speed and stealth; I will utilize the `Asyncio` framework combined with `HTTPX` for high-concurrency scraping that minimizes server load while maximizing polling frequency. To handle modern anti-bot measures like Cloudflare or DataDome, I will implement `Playwright` with stealth configurations or utilize specialized residential proxy rotation to prevent IP blacklisting. The core logic will feature a lightweight hashing system and a localized `SQLite` database to track item states, ensuring that alerts are only triggered for truly "new" entries without redundant duplicates. The final deliverable will be fully containerized using Docker, allowing you to deploy the script on a VPS for stable 24/7 operation with minimal maintenance. Does the target e-commerce site require an active user session or login to view the latest inventory, or is the data publicly visible? Furthermore, do you have a preferred notification platform like Telegram or Slack, or should I build a custom dashboard for these alerts? I am available to jump on a brief call or discuss further via chat to clarify these requirements and ensure the architecture is perfectly aligned with your goals. I look forward to hearing from you.
