GitHub Sponsors Profile

I'm an information security engineer who specializes in defensive "blue team" operations. Most of my hobbies are also related to infosec, so I often write software that helps incident responders like me or answers questions that spark my curiosity.
When I first learned about the DMARC email authentication standard, I immediately understood what a positive impact it could have in preventing malicious email spoofing. At that time, I discovered there were no open source tools for checking DMARC records or analyzing DMARC reports, so I wrote my own and provided it to the community. Since then, I've been amazed by how popular the software projects have become, and I'm very grateful for the code, documentation, and debugging contributions that others have provided.
Occasionally, I've be asked if I accept donations for my projects. I never imagined that I would someday maintain a project worthy of donations, so for a long time, I had no idea how to respond. I've decided to begin accepting donations through GitHub Sponsors. What I share on this account are hobby projects and I have a full-time job, so I can't make any promises about project development, but I am happy to accept any donations.
If you find my projects useful, please consider sending me a small donation. Thanks!
