I'm a blockchain engineer. For the last several years I've worked on Polkadot — one of the larger blockchain networks — at the layer where cryptographic identity and on-chain reputation stop being whiteboard abstractions and become code real users have to trust. I began on the developer-support team at Parity Technologies, where I helped create the Polkadot StackExchange and became one of its top-five all-time contributors, wrote official SDK tutorials and documentation, and presented to developer audiences around the world. I then co-founded R0GUE, a developer-tooling company backed by a Web3 Foundation grant and a $587K Polkadot Treasury allocation, where we built a Rust-based developer CLI and acquired the ink! smart-contract language from Parity. Today I'm a developer relations engineer for Polkadot and the creator of the Polkadot Cookbook, and I've spoken at blockchain conferences across the US, Europe, and Asia.
