Hire an API Developer
APIs as products: designed for their consumers, documented, versioned and observable — the connective tissue done so well nobody thinks about it.
An API is a promise made in public: this is what the data looks like, this is what errors say, this is what happens at the edges. Most API pain — in apps consuming them and teams maintaining them — traces to the promise never being designed: response shapes improvised per endpoint, errors that say "error", versioning by accident. The work here treats the contract as the product and the code as its implementation.
Typical engagements: REST and GraphQL APIs built to spec for web and mobile consumers, public API design for products opening platforms, webhook systems with the full retry/signature/observability treatment, and integration builds connecting your systems to the services your business runs on.

Questions
Asked about APIs.
REST for public APIs with diverse consumers and cacheable resources; GraphQL when one product front end needs precise data shapes over mobile links. GraphQL is a tool for a specific problem, not a maturity badge — most internal APIs are better REST, done properly.
Yes — and the engineering value is in what nobody demos: failure handling. Retries with backoff, idempotency keys, reconciliation when the two systems disagree, monitoring when the nightly sync silently stops. Integrations that assume APIs always work are the ones that fail in production.
Focused APIs and integration projects land between $2k and $20k; platform-scale public APIs run higher. The spec is the contract — you see endpoint models, error shapes and auth design in the quote, before any code.
