I'm calva — also known as calvadev online. I'm a commerce cowboy, free market maximalist, nurture capitalist, and the founder of Self-sown.
I build products and write about the things I care about: Bitcoin and the Lightning Network, the Nostr protocol, free markets, and learning in public. You can find my essays, talks, and sauna logs under Thoughts, and my resume, projects, and professional history under Proof of Work.
In the age of automation, I believe human inputs become the most valuable resource we have — so I spend my time on judgment, taste, and building things that last. If you want to collaborate, ask a question, or just say hi, the contact page lists every way to reach me.
