Skill Profile
API Design & Integration
"The observable action of designing, building, and connecting interfaces that allow software systems to communicate — making data and functionality available in predictable, documented ways."
YOUR SKILLS
Problems This Skill Solves
- Two teams cannot share data because their systems have no agreed-upon interface.
- A third-party integration breaks every time the upstream service makes undocumented changes.
- An API is so poorly documented that consuming teams spend days guessing how to use it.
- A mobile app and a web app duplicate the same business logic because they have no shared backend.

"REST is always the right choice for APIs"
REST, GraphQL, gRPC, and WebSockets each solve different problems — choosing well requires understanding the communication pattern needed.
"RESTful conventions solve most API design problems — if you follow the HTTP verbs correctly, the API will be usable."
REST conventions address URL structure and verb semantics, not the harder design decisions: how to version breaking changes, how to handle partial failures in multi-step operations, what error payloads should contain, and how to design pagination that remains consistent as data changes. An API that follows REST conventions can still be unusable in production.
Research & Outlook
APIs are the connective tissue of modern software. Every system integration, third-party service, and platform feature depends on this skill.
