About me

Hi, I’m Ce

Also known as Elsche, UrSourceCode, and musankmewink. I’m learning cloud security, reverse engineering, and digital forensics, and I use this site to document security research, infrastructure projects, and technical notes.

Over the past year, I started diving back into security and infrastructure after joining the infra and security team at my current job. I've been doing a bit of research and am currently brewing notes to document my findings.
