• Implement front-end integrations using JavaScript, jQuery, HTML, and CSS.

What We’re Looking For

• Someone who respects Swiss standards of quality — structured, disciplined, and dependable.

• A long-term collaborator who communicates clearly, solves problems independently, and continuously improves.

• You’re not rigid — you bring expertise but stay flexible, open-minded, and receptive to feedback.
• Portfolio showing high-quality web apps, e-commerce platforms, membership sites, payment APIs, and dynamic content systems.
