- Experience designing or operating usage-based metering and billing systems.
- Experience building reporting APIs, bulk export pipelines, or streaming event feeds and their associated developer experiences.
- Experience owning platform APIs consumed by internal teams and external customers across design, versioning, and deprecation.
- Experience automating manual, spreadsheet-driven business processes.
- Experience with NIST 800-63-3, OAuth 2.0, or OpenID Connect.

- Experience improving engineering culture through documentation, technical standards, architectural review, and developer experience improvements.
