Hey, I'm Karsten. I'm 16Loading..., based near San FranciscoLoading..., and I build across the stack, cybersecurity tools, polished interfaces, backend systems, automation, and hardware projects. I like hard technical problems in any form, finding bugs, building reliable systems, testing real attack surfaces, designing fast interfaces, and shipping tools people can actually use.

I've worked on frontend and backend apps, UX/UI systems, developer tools, AI workflows, browser automation, security research, and small products that move from idea to demo fast. Lately, I'm focused on agentic security, fast interfaces, and practical systems that connect software, infrastructure, and hardware.
