Custom Backend Development

Robust backend systems engineered to handle your traffic on day one and every day after.

What We Build

Our approach to Custom Backend Development

A great backend is invisible — it just works, scales, and doesn't become a bottleneck as your product grows. We build systems in Node.js, Python (FastAPI, Django), and NestJS with clean architecture, comprehensive tests, and the documentation your team needs to take ownership.

From RESTful APIs and GraphQL services to complex microservices architectures, we design for the scale you're heading toward — not just where you are today. Clean code, proper separation of concerns, and no shortcuts that become technical debt in three months.

Custom Backend Development
Why EagliX

What Makes Us Different

Clean Architecture by Default

Domain-driven design, separation of concerns, and code your team can actually maintain. No spaghetti, no magic, no 'only the original dev knows how this works.'

Tested From Day One

Unit tests, integration tests, and e2e coverage ship with every project. Minimum 80% coverage guaranteed. No more guessing if a change broke something downstream.

Security-First

OWASP best practices, proper auth patterns (OAuth2, JWT), input validation, rate limiting, and secrets management built into every project — not added as an afterthought.

API-First Design

Every endpoint is documented with OpenAPI/Swagger. Your frontend, mobile, and third-party partners get clear, versioned API contracts before a line is written.

Deliverables

Everything You Get

No ambiguity. Every engagement comes with a clear scope and defined deliverables agreed upon before work starts.

  • RESTful API or GraphQL service
  • Database schema design and migration files
  • Authentication and authorization system
  • Comprehensive test suite (unit + integration, 80%+ coverage)
  • OpenAPI / Swagger documentation
  • Rate limiting, error handling, and structured logging
  • Docker containerization
  • Deployment-ready configuration and environment setup
