Summary
Sébastien Axinte is a Senior Engineering Manager based in London with 11 years of engineering leadership and over 15 years of hands-on web development experience, known for turning front-end modernization projects into measurable business outcomes. He has led cross-functional Growth squads at Busuu—coordinating backend, web, and mobile teams—to improve top-of-funnel metrics, enable multi-platform experiments, and introduce company-wide hiring and personal development processes. Previously he drove high-traffic redesigns and migrations (including major RTL and Busuu web projects) and improved performance and deployment autonomy by introducing CMS, unit testing, and ES6 across platforms. Comfortable switching between strategic leadership and technical decision-making, he’s also stepped in as interim Head of Engineering and coached other managers, showing a pattern of scaling teams and practices beyond his immediate remit. An early career emphasis on UX, prototyping and cross-browser problem solving informs his pragmatic approach to balancing refactor work with product delivery.
