I will develop advanced nodejs web crawler and dynamic web scraper
Takashi T.
Over deze dienst
Need a robust data pipeline or automation tool? If generic scripts fail on modern web architectures, you are in the right place.
I am a Senior Software & Security Engineer specialized in high-concurrency backend infrastructure and advanced web crawling. I build production-ready extraction tools that succeed where others fail.
## ️ My Technical Expertise:
* **Dynamic & SPA Scraping:** Advanced Node.js & Puppeteer automation for complex apps (React/Vue/Angular) with heavy JS rendering.
* **Anti-Bot & WAF Bypass:** Smart strategies to bypass modern protections by handling custom headers, sessions, AJAX, and WebSockets.
* **High-Concurrency Systems:** Scalable backend crawlers with efficient task distribution, queue management, and content de-duplication.
* **AppSec & Network Tooling:** Custom vulnerability scanning tools, automated DAST utilities, and secure backend scripts.
## ️ NOTE BEFORE ORDERING:
Every target system has unique rate limits and technical barriers. To ensure accurate pricing and success, **PLEASE MESSAGE ME** with your target URL and requirements **BEFORE** placing an order. Let's talk!

Veelgestelde vragen
Can you scrape websites that require login or have strict anti-bot protections?
Yes. Using Node.js and Puppeteer, I can simulate real user behavior, manage active sessions, handle cookies, and bypass common dynamic rendering or WAF barriers. However, please message me first to evaluate the target site's specific technical complexity.
Do you provide scalable corporate solutions or custom network utilities?
Absolutely. Beyond simple scripts, my expertise lies in designing high-concurrency backend architectures, custom distributed task dispatchers, and automated security scanning tools (DAST). Feel free to discuss your enterprise requirements with me.
What deliverables will I receive upon project completion?
You will receive clean, production-ready, and fully commented source code tailored to your environment. Depending on your selected package, I can also deliver the extracted data (JSON/CSV/SQL) and provide deployment guidance or Docker configuration.
