• Agile delivery: Comfortable working in Agile methodologies.
• Communication: Solid command of written and spoken English, min. B2.

• Full-stack range: Comfortable jumping into TypeScript or React when a project needs you there.
• Cloud and infra comfort: Time spent with AWS, Terraform, or Kubernetes, and a grasp of how your code behaves in production.
• Database depth: Solid experience with SQL and NoSQL (MongoDB a plus), including reasoning about consistency and performance trade-offs.
• Mentoring mindset: You raise the bar for those around you through thoughtful code reviews and shared knowledge.
