API Development
Distributed backend systems for modern platforms.
We design and implement RESTful and GraphQL APIs that handle millions of requests. Versioned, documented, and built for throughput — every endpoint is instrumented, every contract is tested.
// Order Service — gRPC definition
syntax = "proto3";
service OrderService {
rpc CreateOrder(CreateOrderRequest)
returns (Order);
rpc GetOrder(GetOrderRequest)
returns (Order);
rpc ListOrders(ListOrdersRequest)
returns (ListOrdersResponse);
}
message Order {
string id = 1;
string customer_id = 2;
OrderStatus status = 3;
repeated LineItem items = 4;
Money total = 5;
Timestamp created_at = 6;
}What's included
RESTful Design
Resource-oriented architecture with proper status codes, pagination, filtering, and HATEOAS links where appropriate.
GraphQL
Schema-first design with resolvers optimized for query depth. Batching, dataloaders, and persisted queries included.
Authentication & Authorization
OAuth 2.0, API keys, JWT, session management. Role-based access control at the endpoint level.
Rate Limiting & Throttling
Token bucket, sliding window, and concurrent request limiting. Configurable per-client and per-endpoint.
Versioning
URI path versioning and header-based version negotiation. Deprecation policies and migration tooling.
Observability
Structured logging, distributed tracing, metrics aggregation. OpenTelemetry-ready with Prometheus endpoints.
Stack we reach for
We're tool-agnostic but opinionated. These are the technologies we trust for api development.
How we deliver api development
Contract Design
OpenAPI or GraphQL schema defined collaboratively before any implementation.
Architecture Review
Data flow diagrams, caching strategy, and failure mode analysis.
Implementation
Iterative delivery with integration tests for every endpoint contract.
Load Testing
k6 or Locust-based simulation at 10x expected throughput.
Documentation & Handoff
Auto-generated docs, runbooks, and developer onboarding guides.
