Description

Performing custom data extraction, reverse engineering, and target analysis on websites and mobile applications (APKs), using specialized libraries and proxies to safely bypass modern anti-scraping and bot-detection layers (such as Cloudflare or Akamai shields) through emulated requests.

Capabilities & Highlights:

Mobile Application Scraping: Analyzing API requests from decompiled Android applications (APKs) to replicate secure query flows.
TLS Fingerprinting: Mimicking browser TLS handshakes and HTTP/2 patterns to avoid heuristic triggers.
Mesh Proxy Router: Routing scraping tasks across residential IP networks with automated failure recovery.
Automation Shielding: Configuring Puppeteer automation properties to bypass anti-headless test scripts.

My Role

Reverse Engineer & Automation Specialist
Decompiled applications and configured custom HTTP request flows:

Reverse engineered mobile application endpoints (APKs) to replicate data queries directly without browser emulation.
Analyzed obfuscated network payloads and set up automated data pipelines.
Utilized custom stealth browsers to capture dynamic web content securely.
