A day in the life of a serverless developer
summary
A developer turns a synchronous contract API into an async pipeline the same day, replacing a distributed transaction with API Gateway → SQS native integration, a single Lambda consumer, DynamoDB writes using a single conditional PutItem (no prior read), and EventBridge Pipes from DynamoDB Streams to publish events; infra is composed with AWS Infrastructure Composer and SAM, much code generation comes from Amazon Q generated Lambda code, and deployments largely succeed on first try with minor fixes.
