Just Start Building Matters More Than Ever. – Hart Rossman

Hi! I’m Bartosz

I'm Bartosz — a Senior Cloud Security Engineer building at the intersection of AI and security.

I looked for practical, hands-on AI projects built specifically for security engineers — real tools, real stacks, deployable code. I couldn’t find them, so I started building them myself.

Here you’ll find step-by-step tutorials, architectural breakdowns, and honest takes on where AI is taking security operations. Everything is designed to run, fork, or adapt to your environment. Have ideas, tweaks, or want to work together? Reach out 🤝

Let’s create together!
