Summary
🤩
Rockstar🎓
Top SchoolSébastien Lévêque is a seasoned software leader and entrepreneur with 11 years of experience building full-stack web and industrial systems, currently serving as Co-Founder & CTO of YZYflow and CEO of LevHub. He combines deep hands-on expertise in PHP/Symfony, JavaScript/React, HTML5/CSS3 and database systems with a background in embedded and industrial protocols (Profibus, MPI) and low-level languages like C/C++ and assembly. As a former CTO and lead developer at Emisys, he led cross-functional teams across product, DevOps, security and infrastructure, shipping event-management and ticketing platforms at scale. His early career in GIS and ERP development sharpened his data-processing and systems-integration skills, while continuous work on web, SEO/SEM and multimedia tools reflects a pragmatic product mindset. Based in Braine-l'Alleud, Belgium, he blends entrepreneurial drive with technical breadth—equally comfortable architecting cloud infra on Azure or debugging PLC communications. Colleagues note his rare combination of industrial controls knowledge and modern web stack fluency, which helps bridge legacy systems and cloud-native product visions.
