" summary

Claim: serverless replaces EC2 at large scale with 95% cost saving and over 170+ Lambda functions running in production. Built working Search, Timeline and Recommendations APIs using API Gateway, SNS, Kinesis, DynamoDB and proxying legacy endpoints; moved analytics into Google BigQuery. Uses the Serverless framework, CI/CD pipelines, CloudWatch/ELK logging, correlation IDs and a janitor lambda for versions; addresses cold starts, X‑Ray gaps and centralized config via SSM parameter store.
