Cybersecurity website hero concept This concept was designed to address clarity issues in the existing site. The product and its proprietary technology weren’t coming through clearly, which made it hard for visitors to understand what the platform actually does or why it’s different. Another key challenge was visibility and conversion. Important information was missing, and there was no clear path for interested users to get in touch or take the next step. The goal of this hero was to clearly explain the product, introduce technical depth gradually, surface credibility early, and guide the right users toward action. It didn’t ship in this form as we chose a different visual direction, but it reflects how we approach complex cybersecurity products: clarity first, depth second.

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. Technical Details: The application employed a Web Application Firewall (WAF) that stripped standard XSS vectors (parentheses). I successfully bypassed this filter using ES6 Template Literals (backticks) to execute JavaScript. Impact: Reported a P2 Vulnerability that could allow account takeover via session cookie theft. Status: Reported via Vulnerability Disclosure Program (VDP).

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.
