// what I do

• Architecture

  Service boundaries, C4 and contract-first APIs. The boxes-and-arrows part, then the code that follows them.

• Data pipelines

  Batch and real-time ingestion from third parties who swear their data is clean.

• AWS, as code

  ECS, Lambda, Step Functions. Terraform and CDK, because click-ops doesn't have a git log.

• AI-assisted engineering

  Claude Code daily: custom skills, hooks and multi-repo agent orchestration.
