I'm Julien REO

About me

In 2016, after a decade working as a Sales, Business Development, and Marketing Manager across France, Spain, and the UK, I decided to radically shift gears and pursue a career in web development.

Driven by curiosity and a desire to build, I spent a year self-training before launching my journey as a Full-Stack Web Developer in 2017. Since then, my passion for development has only deepened.

I've had the chance to work with companies in a variety of sectors — advertising, digital marketing, web analytics, sports, and video — which gave me a broad perspective on tech challenges and business needs. Over time, I developed a strong expertise in back-end development and quickly moved into Lead Developer roles. These have included full project ownership (from design to deployment), mentoring junior developers, conducting code reviews, maintaining code quality, and overseeing DevOps infrastructure and CI/CD pipelines.

What I love most about this profession is the continuous learning it offers — there's always something new to master. I also thrive in collaborative environments where passionate people come together to solve real problems.

Today, I focus on Node.js projects and specialize in building robust APIs (REST, GraphQL, RPC) and scalable ETL pipelines.
