cak on GitHub • derail at DEF CON
I build security systems that reduce noise and force clarity.
At Posit, I work across product and corporate security for tools used by data scientists worldwide.
I focus on security decisions grounded in real data, not dashboards that look good but say nothing.
All opinions are my own.
I also:
- maintain the web version of HackerTracker
- volunteer as a DEF CON Goon
- contribute to the NumFOCUS Security Committee
