RESTful API Design
We design clean, resource-oriented REST APIs following OpenAPI 3.0 specifications — with consistent error handling, pagination, versioning, and hypermedia links that are intuitive for any developer to integrate.
BACKEND ENGINEERING
APIs & Backends Built for Performance & Scale
We design and build robust REST and GraphQL APIs with sub-100ms latency, 99.9% uptime, and bulletproof security. From single-purpose microservices to complex distributed backends, we engineer the foundation your product depends on.

GraphQL APIs
We build type-safe GraphQL APIs with efficient resolvers, DataLoader for N+1 prevention, persisted queries, real-time subscriptions, and schema-first development with codegen for client type safety.
Authentication & Authorization
Robust auth systems using JWT, OAuth 2.0, and API keys — with role-based and attribute-based access control, token refresh strategies, and seamless integration with identity providers like Auth0 and Cognito.
Rate Limiting & Security
We implement layered security: rate limiting per user and IP, request validation with Zod/Joi, SQL injection prevention, CORS configuration, HTTPS enforcement, and security headers — protecting your API from abuse and attacks.
API Documentation
Auto-generated, interactive API documentation using Swagger UI and Redoc, supplemented with developer guides, authentication walkthroughs, code snippets in multiple languages, and a Postman collection for rapid testing.
Microservices Architecture
When a monolith is no longer sufficient, we architect and implement microservices with gRPC or REST communication, an API gateway, service mesh, distributed tracing, and centralised logging for operational clarity.
How we work
Fixed milestones, working software every fortnight, and no surprises on the invoice.
- 01
API Design & Contract
We define your API contract first — resource models, endpoint design, authentication flows, error codes, and pagination — producing an OpenAPI spec that serves as the single source of truth before any implementation begins.
- 02
Build & Test
We implement the API with a test-first approach: unit tests for business logic, integration tests for each endpoint, contract tests for external dependencies, and automated load tests to verify performance under realistic traffic.
- 03
Security Audit
Every API goes through a security review covering OWASP API Top 10 vulnerabilities, authentication bypass attempts, rate limit validation, injection testing, and mass assignment checks before any production exposure.
- 04
Production Deploy
We deploy with zero-downtime strategies, configure health checks and circuit breakers, set up distributed tracing with OpenTelemetry, and establish SLO-based alerting so you know about degradation before your customers do.
Work we have shipped
Accountable partners, not outsourced vendors
How we price, who we staff and what happens after launch — the parts that decide whether a project actually lands.
Fixed scope, fixed price
You know the cost and the timeline before a line of code is written. No hourly billing, no scope-creep surprises.
You own everything
Full source code, credentials and intellectual property transfer to you on final payment. We sign the IP assignment on day one.
Senior engineers only
Every project is staffed by engineers with years of production experience — no juniors learning on your budget.

Common questions
If your question is not here, a senior engineer will answer it within one working day.
Ask our teamREST is the right choice for most public APIs, simple CRUD operations, and when working with teams unfamiliar with GraphQL. GraphQL excels when clients have diverse data requirements, mobile apps need to minimise over-fetching, or you're building a BFF (Backend for Frontend) layer. Many of our projects use both — a public REST API and an internal GraphQL API for the product frontend.
We implement defence in depth: input validation on every request, parameterised queries to prevent injection, JWT signature verification, CORS whitelisting, rate limiting per user and IP, brute-force protection, security headers (HSTS, CSP), and infrastructure-level WAF rules. All APIs undergo OWASP API Security Top 10 review before launch.
Start with a well-structured monolith — it is faster to build, easier to debug, and simpler to deploy. Migrate to microservices when you have identified specific bottlenecks, need independent scaling of particular domains, or have separate teams that cannot coordinate deployment safely. We actively discourage premature microservices for products under 12 months old.
We use URL path versioning (v1, v2) for public APIs due to its explicitness and simplicity. For internal APIs, we use header-based versioning or GraphQL schema evolution with deprecation directives. We maintain deprecated versions for a minimum of 12 months after announcing sunset dates, giving integrators ample migration time.
We implement distributed rate limiting using Redis with sliding window or token bucket algorithms, configurable per API key, user tier, and endpoint. Limits are communicated via standard headers (X-RateLimit-*), breaches return proper 429 responses with Retry-After headers, and we provide higher rate limit tiers for enterprise customers with SLA commitments.
