The Architecture of Not Waiting
How Lumcast eliminates Lambda cold starts from the user-facing path by pushing every expensive operation into an async pipeline — and why that one decision shapes everything else.

The Trigger Chain: From DynamoDB Row to Running Pipeline
How a single DynamoDB write cascades through Streams, EventBridge Pipe, SQS, and a consumer Lambda to start a Step Functions execution — and the subtle data normalization problem hiding inside.
