// API Development Services
APIs everything connects through.
REST, GraphQL, and event-driven APIs with versioning, OAuth, rate limiting, and documentation. Built to be the layer your products — and your partners — depend on for years, not quarters.

What We Build
API layers designed as contracts first — then engineered for throughput and abuse resistance.
mod_rest
active
REST APIs
Resource-oriented HTTP APIs with versioning, cursor pagination, filtering, and OpenAPI 3.1 specs shipped alongside the code.
OpenAPIJSON:APIHTTP
mod_graphql
active
GraphQL & Federation
Typed schemas, resolvers, persisted queries, and DataLoader batching to eliminate the N+1 problem before it reaches production.
ApolloHasuraRelay
mod_rpc
active
gRPC & Internal RPC
Strong contracts and efficient binary transport for service-to-service calls where both ends are ours to control. Deliberately not a partner-facing API.
ProtobufgRPCBuf
mod_events
active
Webhooks, Queues & Events
Signed outbound events, exponential retry queues, idempotency keys, and replay tooling so no partner misses a payload.
KafkaRabbitMQHMAC
mod_stream
active
WebSockets & Server-Sent Events
Live surfaces — order books, job progress, notifications — paired with a reconnect and backoff strategy rather than just an open socket.
SSEWebSocketBackoff

Third-Party Integrations
Stripe, Twilio, Salesforce, HubSpot, ERP, and bespoke partner systems wired together with sync jobs and conflict handling.

API Capabilities
The engineering that makes an API dependable under load and under scrutiny.
[01]
api
API Design & Modeling
Resource modeling, contract design, and a published OpenAPI 3.1 spec before implementation starts.
[02]
api
REST Architecture
Versioning strategies, cursor pagination, cache headers, and consistent machine-readable error envelopes.
[03]
api
GraphQL & Federation
Schema-first design, real-time subscriptions, and Apollo Federation across independently deployed services.
[04]
api
Service-to-Service Contracts
Protobuf-defined interfaces with Buf linting and breaking-change detection in CI, so a breaking change cannot merge unnoticed.
[05]
api
Authentication & AuthZ
OAuth 2.1, API keys, short-lived JWT rotation, granular scopes, and role-based authorization.
[06]
api
Rate Limiting & Quotas
Token buckets, per-key quotas, burst allowances, and transparent 429 responses with Retry-After headers.
[07]
api
Webhooks & Streaming
Signed payloads, exponential backoff, dead-letter queues, and event replay tooling for partner recovery. Queue choice is driven by delivery guarantees, not fashion: Kafka for high-throughput ordered event streams, RabbitMQ for routed work queues.
[08]
api
Third-Party Integrations
ERP, CRM, payments, logistics, and marketing APIs with scheduled sync and two-way reconciliation. Enterprise SSO arrives as SAML or OIDC, not a bespoke login form.
[09]
api
Observability & SLOs
Structured logs, distributed tracing via OpenTelemetry, uptime probes, and latency dashboards against published SLOs.
// 03_api_pipeline
API Delivery Pipeline
Contract-first development from consumer mapping to production SLA.
phase_01
Discover
Map every consumer, document current flows, and identify where integrations break today.
phase_02
Design
Contract-first design: schemas, versioning plan, auth model, and a spec partners can review.
phase_03
Develop
Endpoints built with validation, contract tests, and SDKs generated from the same source of truth.
phase_04
Deploy
Gateway rollout, sandbox keys, staged partner onboarding, and usage dashboards from day one.
phase_05
Grow
Deprecation cycles, new endpoint surfaces, and SLA tuning as request volume climbs.
