I'm a senior software engineer with experience in embedded systems programming, full-stack development, and Web3/blockchain. I'm based in the UK, and hold a BA and MSc in Natural Sciences (Chemistry) from the University of Cambridge.

I was previously employed as a technical lead for Cisco Systems, where I worked on the operating systems of carrier-grade routing hardware, before leaving the world of IT to work as an English teacher.

While teaching I became interested in Web3 and blockchain, which led me back to IT on a freelance basis, and since 2015 I've been working with Ethereum and other cryptocurrencies.

In 2020 I joined SmartPiggies, Inc. as a founder. As a company we've been building a peer-to-peer derivatives market on the Ethereum blockchain.
