API Design & Development

Gedank Rayze specializes in designing and building high-performance, scalable APIs that power modern applications. With experience spanning 7+ years of API platform ownership at vzaar and countless enterprise integrations, we deliver APIs that developers love to use.

API Paradigms

REST APIs

Industry-standard HTTP APIs with modern best practices:

  • OpenAPI 3.1 - Specification-first design with automatic documentation
  • JSON:API - Standardized response formats
  • HATEOAS - Hypermedia-driven APIs for discoverability
  • Versioning strategies - URL, header, and content negotiation

GraphQL

Flexible query language for complex data requirements:

  • Schema design - Type-safe, self-documenting APIs
  • Resolvers - Efficient data fetching strategies
  • Subscriptions - Real-time data with WebSocket transport
  • Federation - Distributed graph architecture

tRPC

End-to-end typesafe APIs for TypeScript applications:

  • Zero schema declaration - Types flow from backend to frontend
  • Full-stack type safety - Catch errors at compile time
  • Procedure-based - RPC-style API design
  • React Query integration - Seamless data fetching

Real-Time APIs

WebSocket and event-driven communication:

  • WebSockets - Bidirectional real-time communication
  • Server-Sent Events - One-way streaming
  • Socket.io - Cross-browser real-time engine
  • Pub/Sub patterns - Event-driven architectures

Technology Stack

Backend Frameworks

Node.js/Bun Ecosystem

  • Fastify - High-performance with schema validation
  • Hono - Ultrafast for edge deployment
  • Express - Flexible and battle-tested
  • Nest.js - Enterprise-grade with decorators

Python

  • FastAPI - Modern, fast, automatic OpenAPI docs
  • Flask - Lightweight and flexible
  • Sanic - Async Python framework

Specialized

  • ArangoDB Foxx - Microservices inside the database
  • OpenResty - High-performance Lua scripting
  • Cloudflare Workers - Edge API deployment

API Gateways & Management

  • Kong - Open-source API gateway
  • AWS API Gateway - Managed serverless APIs
  • Cloudflare API Shield - Edge API protection
  • Rate limiting - Throttling and quota management

Database-Native APIs

ArangoDB Foxx Microservices

Deploy APIs directly inside your database:

  • Zero network latency - API runs next to data
  • JavaScript/TypeScript - Familiar development experience
  • Built-in routing - Express-like request handling
  • Graph traversals - Complex queries in single requests
  • Transactions - ACID guarantees within services

Multi-Model Queries

  • Graph + document + key-value in single queries
  • AQL (ArangoDB Query Language) optimization
  • Clustered deployments for scale
  • Real-time change notifications

Edge API Deployment

Cloudflare Workers

Deploy APIs at the edge, closer to users:

  • Sub-millisecond cold starts - Instant response times
  • Global distribution - 300+ edge locations
  • D1 Database - SQLite at the edge
  • R2 Storage - S3-compatible object storage
  • AI inference - Run models at the edge

Netlify Functions

Serverless API endpoints:

  • Automatic deployment - Git-based CI/CD
  • Identity integration - Built-in auth
  • Background functions - Long-running tasks

Security & Authentication

Authentication Protocols

  • OAuth 2.0 / OIDC - Industry-standard auth flows
  • JWT - Stateless token authentication
  • API Keys - Simple service-to-service auth
  • mTLS - Certificate-based authentication

Security Best Practices

  • Input validation and sanitization
  • Rate limiting and DDoS protection
  • CORS configuration
  • Security headers (HSTS, CSP)

API Documentation

  • OpenAPI/Swagger - Interactive API documentation
  • Redoc - Beautiful API reference docs
  • Postman Collections - Ready-to-use examples
  • SDK generation - Auto-generated client libraries
