Hi, I am David Molnar

I build useful things with software, hardware, and Bitcoin.

I am a senior software engineer with 15+ years of hands-on work behind me, including 8 years in Bitcoin privacy. I spent six years at Wasabi Wallet, eventually as CTO; today I work independently on software, hardware, and Bitcoin projects that are worth building properly.
