APIs your consumers can actually rely on.
We design and build APIs that are well-documented, consistently structured, securely authenticated, and operationally observable. REST and GraphQL. NestJS, FastAPI, Laravel — the right backend for your requirements. API-first as standard practice.

API work
we do regularly
REST API Design & Development
Resource-oriented REST APIs following proper HTTP semantics — correct status codes, consistent error responses, versioning strategy, pagination, filtering and sorting. OpenAPI 3.1 documentation included. Backends: NestJS, FastAPI, Laravel, ASP.NET Core.
GraphQL API Development
Schema-first GraphQL with Apollo Server (Node.js), Strawberry (Python), or Lighthouse (Laravel). DataLoader for N+1 prevention, subscription support for real-time data, persisted queries for production efficiency.
Third-Party API Integration
Integrating with payment providers (Stripe, Afterpay, PayPal), communication platforms (Twilio, SendGrid), CRMs (Salesforce, HubSpot), ERPs (SAP, Xero, MYOB). Retry logic, circuit breakers, dead-letter queues.
Webhook Systems
Inbound webhook receivers (Stripe, GitHub, Shopify) with signature verification, idempotency handling, and queued processing. Outbound webhook systems for notifying customers or partners of platform events.
API Gateway & Management
AWS API Gateway, Kong, or Nginx for routing, rate limiting, authentication, and logging across multiple services. Developer portal, API key management, usage analytics.
API Modernisation
Migrating legacy SOAP/WCF/XML services to modern REST or GraphQL. Versioning existing APIs without breaking consumers. Building adapter layers for transition periods.
Who hires us
Product teams whose APIs are consumed by mobile, web, and partners
You need an API that works reliably as a contract — well-documented, versioned, and stable enough that consumers can build against it without calling you every week.
Companies integrating with third-party APIs that keep breaking
Your Stripe, Salesforce, or ERP integration fails silently. Nobody knows until a customer complains. We build integrations with the observability and resilience that most initial implementations skip.
Startups launching an API for external developers
A public API is a product. Documentation, authentication, rate limiting, error responses, and changelogs are not optional features — they're what determines whether developers adopt your API or abandon it.
Enterprises retiring legacy SOAP or XML services
Need an API spec reviewed before development starts?
We'll review your planned API design, flag issues with authentication, versioning, and error handling before a line of code is written. Free — and faster to fix issues in spec than in code.
API-first.
Documented.
Integration-grade.
API-first is how we start every project
Authentication done correctly, every time
Third-party integrations that don't break
Documentation is a first-class deliverable
API-First vs Code-First
| Dimension | Code-first (typical approach) | API-first (EB Pearls standard) |
|---|---|---|
| When does the contract exist? | After backend is built |
✓ Before a line of implementation code
|
| Can frontend/mobile build in parallel? | ✗ Wait for backend |
✓ Build against spec immediately
|
| Documentation | ✗ Written after — often skipped |
✓ Generated from code, always current
|
| Integration testing | ✗ Discovered during integration |
✓ Contract tests validate both sides independently
|
| Breaking change detection | ✗ Manual review |
✓ OpenAPI diff in CI — caught before merge
|
| Third-party integrations | ✗ Happy path only |
✓ Retry, circuit breaker, DLQ built in

From kick-off to production
API Design & Contract
Write OpenAPI spec. Define authentication, versioning, error responses. Consumer review and sign-off before implementation.
Weeks 1–2
Core Implementation
Build API endpoints, business logic, data access layer. Auto-generate documentation from code. Unit and integration tests throughout.
Weeks 3–8
Integration & Auth
Wire third-party integrations with resilience patterns. Implement auth flows. Build webhook systems. Run contract tests.
Weeks 9–12
Production & Docs
Deploy to production. Publish hosted documentation. Configure rate limiting, monitoring, alerting. Handover and integration guide.
Final 2 weeks
How to work with us
Fixed-Price API Build
Defined scope and timeline. API contract agreed upfront, implementation delivered against it. From REST APIs to enterprise API platforms.
API Retainer
Ongoing API development, versioning, third-party integration management, and documentation updates as your product evolves.
API Design Review
We review your existing or planned API design, identify issues with auth, versioning, and error handling, and produce a prioritised improvement list.
Every question answered.
Designing and specifying the API contract (OpenAPI spec) before writing implementation code. Both backend and frontend/mobile teams agree on the contract first. Eliminates the most common integration bugs and enables parallel development without coordination overhead.
Yes. We assess the existing service, design the REST replacement, build an adapter layer that lets new systems integrate before the legacy system is decommissioned, and handle the migration without breaking existing consumers.
Yes — AWS API Gateway, Kong, or Nginx for routing, rate limiting, authentication, and logging across multiple backend services. Developer portal setup, API key management, and usage analytics. We recommend the right gateway based on your infrastructure and team size.
Build an API your consumers can rely on.
45 minutes. We'll review your requirements, discuss the API design, and give you a realistic view of scope, timeline, and what it takes to build an API that lasts.
