API
Development

We map who will consume the API — your own apps, partners, or paying customers — and what operations and data each consumer actually needs. This determines the protocol choice, authentication model, and how strict versioning needs to be.

We write the full OpenAPI or GraphQL schema before any implementation: resources, naming, error formats, and pagination conventions. The contract is reviewed with your team and frozen, so client development can start immediately against mocks.

Endpoints are built with validation at the boundary, idempotency keys for payment-like operations, and structured logging from the first commit. Every endpoint ships with automated tests covering both happy paths and failure modes.

We implement OAuth 2.0 or API-key authentication, scope-based authorization, input sanitization, and rate limits per consumer tier. The API is reviewed against the OWASP API Security Top 10 before anything reaches production.

We benchmark realistic traffic patterns and tune the slow paths — N+1 queries, missing indexes, oversized payloads — until p95 latency meets the agreed budget. Caching layers with Redis are added where they pay off, not by default.

You receive interactive API docs, a Postman collection, code examples, and a changelog process for future versions. We define deprecation policies up front so evolving the API never strands existing integrations.
