🔐 Web Application Security Engineer

Freelance Web Application Security • Authentication • API Security • Access Control • Manual Black-Box Testing with Fix-Focused Reporting

About

I help developers, startups, and small teams identify real, exploitable security risks in web applications before attackers or bug bounty hunters do.

My testing focuses on realistic attack paths including authentication bypass, API authorization failures, data exposure risks, and business logic abuse.

I specialize in manual security testing — not automated scanner reports — with clear remediation guidance developers can implement quickly.
