I’m Celestin Rumo, a Front-End Engineer with a BSc in Telecommunications and 8 years in IT, including 4 years focused on frontend development as an R&D engineer. I combine user-centric thinking, technical rigor, and genuine human engagement to create intuitive, aesthetic, and seamless interfaces. I’m passionate about innovation, continuous improvement, and delivering value by aligning business needs with real user feedback. I’m a reliable, committed, and honest team player who communicates clearly and supports colleagues to achieve shared goals. I also bring leadership experience from ski schools, where I managed operations, trained instructors, and shaped digital communication strategies. I supervised daily operations, scheduling, client relations, and coordinated large teams (up to 125 instructors). As Head Coach, I designed and implemented internal training programs to develop pedagogical and technical skills. These experiences have strengthened my ability to foster team cohesion, keep a positive, motivating environment, and translate user needs into practical solutions.
