Scalable API Development for Data-Heavy Platforms.

We architect and develop robust REST & GraphQL backends optimized for external developer adoption and high-frequency internal use.

The High Cost of Poor API Design

!

Inefficient loops fetching the exact same data dozens of times per page load (N+1 query issues).

!

Lack of rate limiting, entirely exposing your database to scrapers or DDoS attacks.

!

Inconsistent JSON payload structures forcing frontend engineers to write messy parsing logic.

!

Zero automated documentation, making developer onboarding a nightmare.

Strict RESTful Standards & GraphQL Schemas

An API is a product in itself. We construct backend architectures that prioritize predictable interface contracts. Using heavy caching layers (Redis) and rigorous authentication standards (OAuth 2.0 / JWT), our APIs safely decouple your proprietary data layer from the consumer clients.

What's Included

  • Containerized API microservice (Docker)
  • Comprehensive Postman Collections for all endpoints
  • Rate limiting and abuse prevention configurations
  • Database connection pooling architecture

How We Work

1

Schema Design

Designing the exact JSON interface contracts and planning HTTP verb compliance.

2

Logic Implementation

Building the controller logic, data abstraction layers, and JWT authentication flows.

3

Load Testing

Aggressive load testing using Artillery or K6 to guarantee endpoints support projected traffic.

Type-Safe Contracts

Utilizing tRPC or Zod validation to ensure payloads are perfectly strongly-typed end-to-end.

Bank-Grade Auth

Implementation of secure rotating refresh tokens and httpOnly cookie protections.

N+1 Elimination

Deeply optimized ORM queries targeting sub-50ms execution times for heavy JOIN tables.

Frequently Asked Questions

Should we use REST or GraphQL?

REST is best for public simplicity and caching. GraphQL excels at highly related data models where the frontend needs exact payload control. We can advise during discovery.

Can you wrap our legacy SOAP system into a modern REST API?

Yes, we frequently build middleware adapters to modernize enterprise legacy systems for modern web consumption.

How do you secure API routes?

We deploy strict JWT validation, CORS whitelisting, payload sanitization (against SQLi), and progressive rate-limiting buckets.

Custom Backend API Architecture for Web and Mobile

Modern software relies on decoupled connectivity. A specialized API development agency understands that your backend is the nucleus of your digital operation. By implementing strict OpenAPI specifications, Node.js performance tuning, and Redis caching layers, Dazzcode guarantees that your external facing interfaces are resilient against massive traffic spikes while providing a flawless developer experience for third-party integrators.
