Hands-on experience with cloud-native infrastructure (AWS preferred), container orchestration (Kubernetes, Docker), and infrastructure-as-code practices

Proficiency in one or more modern backend languages (Node.js, Kotlin, Go, Python, or Java) and data technologies (PostgreSQL, DynamoDB, Redis, Elasticsearch, etc.)
