About Instructor

Hi! My name is Julien and I am the instructor of EatTheBlocks Pro.

I am a senior Blockchain software engineer. I used to work in Finance, and I switched to software development 6 years ago.

For the past 3 years, I have been building Dapps and Solidity smart contracts for several Ethereum and ICOs projects, including Lendingblock, an institutional crypto lending exchange.

I run EatTheBlocks, a youtube channel for Ethereum developers. I have also published a Blockchain course for Manning.

I also contribute to the code of Drizzle and I spoke at TruffleCon 2019 on Drizzle.

I also have extensive experience with Nodejs, Javascript & React, having worked as a full-stack software engineer for the last 6 years.
