WAF Bypass & XSS Discovery for E-Commerce Platform Conducted a black-box security assessment for a high-traffic e-commerce marketplace (10M+ users). The Finding: Reflected Cross-Site Scripting (XSS) in the search functionality.

Custom OSINT Automation Tool (Python) I developed a custom Python utility to automate the reconnaissance phase of security assessments. Problem: Manual Google Dorking and server status checking consumes valuable time during an audit. Solution: I wrote a Python script utilizing urllib and webbrowser modules to: Automate complex Google Dork queries for finding exposed environment files and admin panels. Batch-process server status checks (HTTP 200/403/404) to identify live targets instantly. Outcome: Reduced reconnaissance time by 90% for large-scope targets.
