Cloud and serverless platforms on AWS

A serverless architecture is cheap to start and expensive to correct. We design around the platform's real constraints from the outset: the origin timeout a CDN enforces, the item-size cap on a database record, the per-second ceiling on an email send. Each one is a boundary a happy-path demo never reaches and a production workload finds in its first month.

The building blocks are Lambda, DynamoDB with a single-table design, S3 behind CloudFront, and SES. Data stays in the region it is meant to stay in — for UK clients that means eu-west-2 and nowhere else.

We run what we build. Infrastructure is defined in code, deployments repeat exactly, and the alarms that matter are wired before launch rather than after the first incident.
