AWS Serverless—built on AWS Lambda, Amazon DynamoDB, Amazon SQS/SNS, API Gateway, and AWS Cognito—allows platforms to process millions of daily events without managing idle EC2 servers. However, achieving sub-50ms latency and predictable AWS bills requires single-table DynamoDB key design, cold-start tuning, and Dead-Letter Queue (DLQ) resilience.
If you need to hire a freelance AWS serverless programmer experienced in Python, Go, and Node.js/TypeScript on AWS, I am Aldian Fazrihady.
