API Delivery Is Fast and Design-First

API delivery must follow a design-first approach with mock servers, contract testing, and schema registries that enable parallel development, allowing consumers to begin integration before implementation is complete and accelerating the overall time from concept to production.

Policies

API-First Design

API-first means the contract comes before the code. When the OpenAPI spec is the source of truth and consumer needs drive the design, you end up with better APIs that people actually want to use.

API Mocking

Mock servers generated from API contracts let consumers start integrating before the implementation is done. This is what design-first looks like in practice -- parallel development that actually w...

Contract Testing

Contract testing validates that the actual implementation matches the OpenAPI spec. Consumer-driven tests catch drift between the contract and reality before it breaks anyone's integration.

Schema Registry

A schema registry centralizes your data models with versioning and compatibility checks. Publishing and consuming shared schemas from a registry reduces duplication and keeps data consistent across...

Linting in CI

Running linting rules in CI/CD is where governance becomes automated. Spectral rules, severity levels, and pass/fail decisions baked into the pipeline mean governance happens on every commit, not j...

Sandbox Environments

Sandbox environments let consumers explore and test APIs without any risk. Mock servers, sandbox credentials, and sample data are building blocks that accelerate onboarding and reduce integration t...

GitHub Actions

GitHub Actions turn your API delivery into a repeatable pipeline. Governance, validation, testing, and deployment all become automated steps that run consistently every time.

Experiences

Velocity

Velocity matters because the business side isn't going to wait around. I see the gap between what the business needs and what API teams can deliver growing wider, and without repeatable processes a...

Automation

I keep shining a light on automation because it's the only way to scale API operations. When testing, validation, deployment, and governance are all manual, you're just adding human error and slowi...

Collaboration

I see teams producing and consuming APIs in complete silos, with no shared visibility into designs, changes, or decisions. Collaboration isn't just a nice-to-have -- it's a building block that prev...

Quality

I see the quality of APIs eroding across the landscape. Teams ship fast and never look back, but consumers feel every rough edge, every missing example, every inconsistent response. Quality is what...

Self-Service

Self-service is the goal I keep pushing teams toward. If a consumer can't find your API, sign up, get keys, and make their first call without emailing someone, you've created a bottleneck that will...

Developer Experience

Developer experience is the thing I'm most passionate about across the API landscape. Poor docs, missing examples, inconsistent patterns, and no tooling -- these are the things that make developers...
