The Clean Cooling Network (CCN) is a global programme focused on making cooling and cold-chain infrastructure a critical national priority. The platform provides free membership and community resources, expert webinars and news, accredited training through the Clean Cooling Academy, and professional development opportunities for students and industry professionals.

I joined in July 2025 as part of a two-developer team, working on a multi-app Symfony platform spanning membership registration, Academy course applications, employer talent search, and a full website redesign. The work includes Moodle and identity integrations, a shared design system, and moving the members portal into Sulu CMS.
