Rockstar🎓
Top SchoolJulien Déléan is a seasoned technology leader and co-founder with 11 years of experience leading product and engineering teams, currently serving as CTO of Amblea, which centralizes and optimizes medical transport. He blends hands-on front-end expertise—demonstrated by contributions to high-profile open-source terminals like xterm.js and Vercel's Hyper—with product-minded leadership from early-stage startups to regulated operations. Julien has a strong background in mobile and client application development from roles at Winamax and a history of founding technical ventures, giving him both delivery focus and strategic vision. Based in Strasbourg, he pairs system-and-network engineering training from EPITA with practical UX improvements (e.g., keyboard support, focus handling, transparency) that show attention to subtle usability details. Away from the console he’s a craft beer enthusiast, a small but telling hint of a personality that values refinement and community.
