What I'm looking for

I’m looking for opportunities where I can perform hands-on manual penetration testing of web applications, report vulnerabilities with proof-of-concept and impact, and help improve application security through responsible disclosure.

I’m a cybersecurity researcher and penetration tester who delivers hands-on web application security testing through manual methods. I focus on finding real-world weaknesses and translating them into clear, actionable reports.

Since 2022, I’ve worked as an Independent Security Researcher on bug bounty platforms, testing web applications to uncover vulnerabilities such as authentication issues and session management weaknesses. I also evaluate injection points, CSRF issues, and security misconfigurations.

My process centers on responsible vulnerability disclosure, including proof-of-concept and impact analysis, so teams can remediate efficiently. I’m recognized as an Independent Security Researcher—Bug Bounty Switzerland for responsible disclosure in a public security advisory.

I hold a BSc in Computer Science (2019) and continue learning by attending University Technology Workshops focused on programming and emerging technologies.
