Custom API Development
Build scalable, secure APIs that power your applications. REST, GraphQL, or gRPC - designed for performance, security, and developer experience.
API Technologies We Build
Choose the right API architecture for your use case
REST API
Industry standard for web services. Simple, scalable, stateless architecture with HTTP methods (GET, POST, PUT, DELETE).
GraphQL API
Query language for APIs. Fetch exactly what you need in one request. Strongly typed schema with introspection.
gRPC API
High-performance RPC framework using Protocol Buffers. Binary protocol for fast microservice communication.
Complete API Solutions
Everything you need for production-ready APIs
API Design & Architecture
RESTful design following industry best practices. Versioning strategy (URL or header-based). Resource modeling with proper HTTP methods. Pagination, filtering, sorting for large datasets. HATEOAS for discoverability. OpenAPI 3.0 specification.
Authentication & Security
OAuth 2.0, JWT tokens, API keys. Role-based access control (RBAC). Rate limiting and throttling. Input validation and sanitization. SQL injection protection. HTTPS/TLS encryption.
Interactive Documentation
Swagger/OpenAPI docs with try-it-out feature. Code examples in multiple languages
Monitoring & Analytics
Real-time metrics, error tracking, usage analytics, and performance monitoring
Performance & Scalability
Redis caching for fast responses. Database query optimization with indexes. Horizontal scaling with load balancers. CDN integration for static assets. Async processing for long-running tasks. Connection pooling and keep-alive.
Testing & Quality
Unit tests, integration tests, load testing, and automated API testing
Webhooks & Events
Real-time notifications, event-driven architecture, retry logic, webhook management
API Gateway
Centralized gateway for routing, rate limiting, authentication, transformation
API Development Technology Stack
Modern frameworks and tools for building robust APIs
API Development Process
From design to production deployment in 6-10 weeks
Requirements & API Design
1 week
Understand use cases, data models, and integration requirements. Design API endpoints, request/response schemas, and error codes. Create OpenAPI specification. Define authentication strategy and rate limits.
Backend Development
2-4 weeks
Build API endpoints with chosen framework (Express, FastAPI, Spring Boot). Implement business logic and data access layer. Add input validation and error handling. Set up database with indexes and constraints.
Authentication & Security
1 week
Implement OAuth 2.0, JWT, or API key authentication. Add rate limiting and request throttling. Input sanitization and SQL injection protection. HTTPS/TLS setup with proper certificates.
Testing & Quality Assurance
1-2 weeks
Write unit tests for all endpoints (80%+ coverage). Integration tests for end-to-end workflows. Load testing with Apache JMeter or k6. Security testing and penetration testing.
Documentation & Developer Portal
1 week
Generate interactive Swagger/OpenAPI documentation. Code examples in multiple languages (cURL, JavaScript, Python). Getting started guides and tutorials. Postman collection for testing.
Deployment & Monitoring
1 week
Deploy to cloud with auto-scaling and load balancing. Set up monitoring (New Relic, Datadog). Error tracking with Sentry. API analytics dashboard. 24/7 uptime monitoring with alerts.
