Senior🎓
Top SchoolSylvain Denyse is a frontend developer based in Nantes with 10 years of hands-on experience building and modernizing web applications, primarily using React after migrating several Angular and monolithic Symfony projects to decoupled front-end architectures. Currently at Yousign, he focuses on delivering accessible, maintainable front-ends and has a track record of making technical choices, setting up CI environments, and mentoring juniors from his time at KNP Labs and Pepperbay.

Notably, he has practical BI and cross-platform mobile experience from earlier roles and brings interdisciplinary problem-solving skills honed outside tech as a performer and team member in large-scale live productions.
