Professional Summary

I am a security researcher and full-stack developer from the Netherlands. I specialize in Web, Android, and Open Source (OSS) hacking. My background in development allows me to analyze complex codebases and find logic flaws that automated tools miss. I focus on white-box auditing, secure code implementation, and responsible disclosure to help secure the software supply chain.
