• Experience collaborating with DevOps/Platform teams to deploy code on AWS (EKS/ECS, Lambda, API Gateway, RDS/DynamoDB), while not being directly responsible for infrastructure
• Strong understanding and adoption of observability best practices (structured logs, distributed tracing, metrics)

Specific Knowledge - Distributed systems concepts: consistency, concurrency, fault tolerance

• Domain-Driven Design (DDD) and Event-Driven Architecture
