Hire Backend Developers
The backend is where your business logic lives. Anubiz Labs provides backend developers who design APIs, architect databases, implement authentication, build integrations, and write the server-side code that powers your application. Our engineers build systems that are fast, secure, and maintainable — the invisible foundation that makes everything else possible.

We implement, you ship. Async, documented, done in days.
API Design and Implementation
Our backend developers design APIs that are intuitive for consumers and efficient for servers. They build RESTful APIs with consistent resource naming, proper HTTP status codes, pagination, filtering, and comprehensive error responses. They implement GraphQL APIs with optimized resolvers, DataLoader batching, and subscription support for real-time features.
Every API includes input validation, rate limiting, authentication, and authorization. Documentation is generated automatically from code annotations using tools like Swagger, OpenAPI, or GraphQL introspection. Your frontend team, mobile developers, and third-party integrators get clear, accurate API documentation without manual maintenance.
Our developers also build webhook systems, event-driven architectures, and message queue consumers that extend your backend beyond request-response patterns.
Database Architecture and Optimization
Choosing the right database and designing an efficient schema is one of the most impactful decisions in any project. Our backend developers evaluate your data access patterns and recommend PostgreSQL, MySQL, MongoDB, Redis, or specialized databases like TimescaleDB or Elasticsearch based on actual requirements — not personal preference.
They design schemas that balance normalization with query performance, write migrations that can be applied and rolled back safely, implement indexing strategies that keep queries fast as data grows, and set up replication for high availability. When your database becomes a bottleneck, they diagnose slow queries, add appropriate indexes, implement caching layers, and optimize data access patterns.
Security and Authentication Systems
Backend security is not a feature — it is a fundamental requirement. Our developers implement authentication systems with JWT, OAuth 2.0, SAML, and passwordless flows. They build role-based and attribute-based access control that enforces permissions at the API level. They encrypt sensitive data at rest and in transit, manage secrets securely, and follow OWASP guidelines for preventing common vulnerabilities.
They conduct security reviews of existing codebases, identifying SQL injection risks, insecure direct object references, broken authentication flows, and data exposure through verbose error messages. Every fix is accompanied by a test that prevents the vulnerability from reappearing.
For compliance-sensitive applications, our developers implement audit logging, data retention policies, GDPR data export and deletion endpoints, and encryption standards required by regulations like PCI-DSS and HIPAA.
Scalability and System Design
Our backend developers design systems that handle growth without rewrites. They implement horizontal scaling with stateless services, vertical partitioning for database-heavy workloads, caching strategies with Redis or Memcached, and queue-based architectures that decouple processing from request handling.
They understand distributed systems challenges — eventual consistency, idempotency, retry logic, circuit breakers, and graceful degradation. When one service is slow or down, the rest of your system continues to function. Users experience degraded service instead of complete outages.
