APIs that are consistent, documented, and secure.
A well-designed API is the interface between your data and every consumer — your frontend, mobile apps, and third-party integrations. Getting the API design right from the start prevents years of backward-compatibility debt.
Need an API developer for REST API design, third-party integration, or API documentation
API design decisions are permanent — changing them breaks all consumers. The upfront decisions that matter:
Resource naming: REST convention: plural nouns, not verbs. /users not /getUsers. /orders/{id}/items not /getOrderItems?orderId=x.
HTTP status codes: 200 for success, 201 for created, 400 for client errors, 401 for unauthenticated, 403 for unauthorized, 404 for not found, 422 for validation errors, 500 for server errors. Using the right code lets API consumers handle errors generically.
Error response format: Consistent structure across all errors. Example:
{ "error": "VALIDATION_FAILED", "message": "Email is required", "field": "email" }
Pagination: Offset-based (?page=2&limit=20) or cursor-based (?cursor=xyz). Cursor pagination is more reliable for large datasets. Decide once and apply consistently.
Authentication: Bearer tokens (JWT) in the Authorization header. API keys for machine-to-machine. Never in query parameters.
API documentation: OpenAPI/Swagger spec that's generated from the code, not written by hand. Stays current without manual maintenance.

One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
API scope is the resource count and integration points. Fixed-price.
Questions, answered.
REST for most applications. GraphQL for applications with complex data requirements, many consumer types, or a need for client-specified query shapes. REST is simpler to implement, cache, and document.
