Hello! I'm Otto, an experienced full-stack and blockchain engineer who has been involved in the blockchain industry since 2013.

As a developer, I contributed to some relevant projects and startups since the early days of the web3 space.

I also started several popular communities in Spain, including the Ethereum Spain Meetup and Forobits.

More recently, I've been involved in various related activities such as running nodes, working on R&D, hacking in events around the world, and building kyd.wtf: an analytics platform for web3 developers.

You can also find me teaching Ethereum-related subjects to postgraduate students in the Master in Blockchain, Smart Contracts and Cryptoeconomics (Universidad de Alcalá, Madrid).
