Hi, I'm Guillaume Besson

👋🏼

I'm a Full Stack Developer from France.

I'm a freelance full-stack developer with a passion for code and building products. I've been working with awesome companies for more than 9 years and helped them build secure, fast, and maintainable products with quick iterations. When I'm not working for a client, I build my own products and open-source projects.

My tools of choice are Typescript, NodeJS, React, GraphQL, PostgreSQL, and Redis.

You can find me on GitHub, Twitter, and LinkedIn.
