I’m a web scraping and reverse engineering specialist based in Beijing, China. I build reliable data collection tools, automation workflows, and APIs for websites and mobile applications.

• Production-ready web scrapers and Apify Actors
• Structured business, e-commerce, job, travel, and public web datasets
• REST APIs for real-time data collection
• Scheduled monitoring and change-detection systems
• High-concurrency crawlers with retry, deduplication, and proxy management
• Data pipelines exporting to JSON, CSV, Excel, and databases

• Languages: Python, Java, JavaScript, C/C++
• Scraping: Scrapy, Requests, HTTPX, BeautifulSoup, Playwright
• Infrastructure: Docker, Linux, Redis, MySQL, MongoDB
• Mobile research: Android/iOS protocol analysis, JNI and native library analysis
• Reverse engineering: JavaScript, WebAssembly, ARM64, encryption and signature analysis
• Networking: HTTP/1.1, HTTP/2, HTTP/3, TLS fingerprints, proxies and session management

I focus on producing clean, stable, and well-documented tools rather than one-off scripts. My Actors include clear input options, structured output, error handling, retry logic, and practical usage examples.

I care about performance, maintainability, data quality, and the responsible collection of public or properly authorized data.

I’m open to custom web scraping, mobile protocol research, data APIs, automation systems, and challenging data collection projects.

If an existing Actor does not fully meet your requirements, feel free to contact me through Apify and describe the data source, required fields, expected volume, and update frequency.
