Bitcoin, Lightning, QA & open-source infrastructure

Author of Q/A about Bitcoin. QA tester and support for Edge Wallet. I run self-hosted Bitcoin and Lightning infrastructure and publish practical resources for merchants and developers.

About

What I work on

I help people and teams ship reliable software around Bitcoin and self-custody: QA and support for Edge Wallet, consulting with ArkLabs, and public Lightning resources.

Support keeps this work independent — public lists, self-hosted BTCPay, a Lightning node, and open-source tools that do not live on a rented platform.
