Manage databases (PostgreSQL) and authentication (Keycloak or Supabase, OpenID)
Set up and maintain DevOps infrastructure (Docker, Helm, GitOps, AWS, Kubernetes, security best practices)
Collaborate closely with the founder and domain experts (nutrition, product, design)
Ideally you bring
Solid experience in full-stack development (frontend + backend)
Knowledge of Python, JavaScript/TypeScript, and modern web frameworks
Basic familiarity with cloud infrastructure and containerization
Understanding of authentication and data security principles
Willingness to learn across domains — from AI integration to mobile builds
