The Interview

Interviewed by the Ethereum Foundation

During Devconnect 2025, I was selected for an on-camera interview by the Ethereum Foundation team — sharing my journey as a Web3 developer from Costa Rica building on Ethereum and Starknet.

The conversation covered my work on Starknet and EVM-based projects, open source contributions to the ecosystem, and how the scholarship shaped my path as a builder in decentralized technology.
