Developer & Designer
I'm Guillaume, a front-end developer and illustrator. I design and build fast, animated, easy-to-manage websites with a hand-drawn touch.
Bespoke websites and apps with modern designs and seamless functionality.
Cutting-edge designs to enhance your online presence and user experience.
Creative illustrations tailored for your brand and advertising needs.
I use AI every day to ship faster and more reliably. The design decisions stay mine.
AI assistants like Claude Code handle repetitive code, tests and documentation. Timelines get shorter, and I keep my time for what makes your project unique.
Every line suggested by AI is reviewed, tested and understood before it ships. Performance, accessibility and security audits are AI-assisted and signed off by me.
Hand-drawn illustrations, animation, art direction: what gives your site its personality doesn't come out of a generator.

A front-end developer and designer, I come from illustration and music. That sensibility shows in every project: hand-drawn visuals, polished animations and thoughtful layouts. Trained in web development in Paris, I worked at an agency on Drupal websites before launching Webjuno as a freelancer in 2024.
Pages that load quickly and that Google understands. Every site is optimized from the ground up.
