Welcome#

My name is Joel. I'm a software engineer since 2013 (7+ years of professional experience) currenty based in Lyon, France.

I am a curious person with strong interest in data, music technology, distributed systems and blockchain applications (DeFi, NFT, Smart Contracts).

I have worked with a multitude of languages, frameworks, databases and cloud providers. I'm most confortable with Python and Javascript.

Lately, I have been focusing on writing Smart Contracts with Solidity, testing with Waffle/Chai and the Ethers.js/Web3.js libraries.

I enjoy writing clean code. I also have some experience managing software teams using Agile practices (scrum).

I believe that acquiring knowledge, gaining understanding and learning new skills are joyous, empowering events.
