Who I am?

Hello. My name is Adrien Esquerre, I am a certified AWS developer and full-stack developer. I build websites and apps using a wide range of frontend and backend technologies, mainly CSS, JavaScript, React.js, Node.js, WordPress, Python, as well as the latest design tools. Also, I have knowledge about Linux.

I am a teacher Stack Overflow contributor with around 3 years of front and back end web development experience. I have a Lawyer background specialized in intellectual property. Furthermore, I have proven technical Google Ads skills, and I am up-to-date with the latest web technologies and best practices.

Above all, my most valuable perk is the fact that I like to work very hard, simply because this specific field does not demand any particular grievous effort from me, as it has become a way of earning my living doing what I love. Also, I have the ability to learn new things quickly.
