Overview
REST, GraphQL, and event-driven API design and engineering — versioned sanely, documented beautifully, secured properly, and fast at the 99th percentile.
An API is a product with the least forgiving users imaginable: other people's code. It can't be charmed by a nice interface — it either behaves exactly as documented, every time, or integrations break and partners quietly route around you.
We design APIs contract-first. Schema and documentation are written and reviewed before implementation, breaking changes are managed through explicit versioning policy, and every endpoint ships with latency budgets, rate limits, and usage analytics. The result is an interface teams trust enough to build businesses on.

Capabilities
What our apis practice covers
Every engagement is scoped from these building blocks — mixed to fit your product, not a package.
REST & GraphQL design
Contract-first design with OpenAPI and GraphQL schemas — consistent naming, predictable errors, pagination that doesn't surprise anyone.
Event-driven & streaming APIs
Webhooks with signed delivery and retries, Kafka streams, and WebSocket layers for systems where polling can't keep up.
API security & access control
OAuth 2.0, API keys with scoped permissions, rate limiting, and abuse detection — audited against OWASP API Top 10.
Developer experience & documentation
Interactive references, quickstarts that work on the first copy-paste, SDK generation, and sandbox environments.
API gateway & management
Kong, AWS API Gateway, and Apigee implementations covering routing, quotas, analytics, and monetization.
Legacy API modernization
Facades over aging SOAP and ad-hoc endpoints, migrating consumers gradually with zero big-bang cutover risk.
Engagement
How this engagement runs
Four phases with named deliverables — you'll know exactly where the work stands every week.
01
Domain & contract modeling
Resource modeling with your domain experts, producing reviewed OpenAPI/GraphQL contracts before code exists.
02
Build with mock-first integration
Consumers integrate against generated mocks from day one, so client and server development run in parallel.
03
Security & performance hardening
Authorization testing, load benchmarks against latency budgets, and chaos testing of failure modes.
04
Developer experience launch
Documentation portal, SDKs, versioning policy, and usage analytics — the operational side of treating your API as a product.
