Julien C.

Freelance frontend developer passionate with deep expertise inTypeScriptand **React**, I code daily and split my time between freelancing (mainly with tech startups working remotely), open-source, and creating micro-SaaS.

When I'm not coding, I enjoy perfecting my skills by reading classics like Clean Code, The Pragmatic Programmer, Deep Work, TDD, Lean Startup, and Clean Architecture, watching technical conferences on YouTube, or reading articles on Medium, dev.to, Twitter... This commitment allows me to apply best practices and trends in my projects.

As an experienced frontend developer, I transform your ideas into high-performing products. My attention to detail and commitment to best practices ensure scalable solutions and polished interfaces; UX is everything. I quickly integrate into teams and adapt to the specific needs of each project, always bringing innovation and technical excellence.
