Backend & API Services That Power Everything
You need backend development that handles real traffic, real data, and real business logic without falling over. Whether you want to hire a backend development company to build the server-side infrastructure for a new product, bring in experienced backend developers for custom API development that connects your frontend to your data, or need full API development services covering architecture, database design, authentication, and deployment, the goal is always the same: build backend and API systems that are fast, secure, and reliable enough that nobody ever thinks about them.
Backend and API development typically costs between $15,000 and $100,000 depending on complexity, integrations, and scale requirements. A focused API with 10 to 15 endpoints and database setup starts around $15,000. Full backend systems with microservices, authentication, third-party integrations, and CI/CD run $40,000 to $100,000.
Core Capabilities and Features
RESTful API Development
The standard for most web and mobile applications. Your REST APIs are built with clean endpoint design, proper HTTP semantics, consistent error responses, pagination for list endpoints, and comprehensive documentation (OpenAPI/Swagger). Every API is designed for the clients that consume it: frontend applications, mobile apps, third-party integrations, and internal services.
- Clean endpoint design with proper HTTP methods, meaningful status codes, and consistent error responses
- Pagination, filtering, and versioning from day one so future changes do not break existing clients
- Comprehensive OpenAPI/Swagger documentation for frontend, mobile, and third-party consumers
Database Design and Engineering
The database is the foundation of your backend. Your schemas are designed for PostgreSQL (the default for relational data), MongoDB (for document-oriented data), and Redis (for caching, queues, and real-time features). Migrations, indexing strategy, query optimisation, connection pooling, and backup automation are all handled.
- PostgreSQL for relational data, MongoDB for document-shaped data, Redis for caching and real-time features
- Indexes planned during schema design, not added reactively when users complain
- Query performance tested under realistic load before deployment with caching layers that reduce database load by 80 to 90%
Third-Party Integrations
Most applications need to connect to external services: payment processors (Stripe, PayPal), email platforms (SendGrid, Postmark), authentication providers (Auth0, Firebase Auth), cloud storage (S3, Google Cloud Storage), messaging (Twilio, WhatsApp API), and dozens of others. Your integrations are built with proper error handling, retry logic, webhook processing, and fallback behaviour.
- Payment processors, email platforms, authentication providers, cloud storage, and messaging services
- Error handling, retry logic, webhook processing, and graceful degradation for every integration
- Budget 1 to 2 weeks per complex integration with full API client development and testing
Why It Matters
Your users will never compliment your backend. But they will leave the moment it stops working. The backend is the part of your application that determines whether it scales, whether it stays secure, and whether it remains maintainable as your team and codebase grow. A well-built backend handles 10x your current traffic without redesign. A poorly built one starts breaking the moment you get your first real users. The cost of a bad backend is not measured in server bills. It is measured in lost users, security breaches, developer hours spent debugging instead of building, and the eventual realisation that the entire thing needs to be rewritten because it was not designed for the product it became. The teams that get the most from their backend investment are the ones who treat it as infrastructure, not a detail. They invest in API design before coding. They write tests. They monitor. They document. And they build for the scale they are growing into, not just the scale they have today.
By the Numbers
$16.29B
The API economy is growing at 34% annually. APIs are business products that drive revenue, enable partnerships, and power every digital experience.

90%
Over 90% of new enterprise applications use APIs as core architecture. Building without APIs is building without a future.

354
The average enterprise manages 354 APIs. Each needs design, security, monitoring, and documentation.

$4.5M
API security incidents are among the most expensive breaches. Broken access controls account for 40% of all API attacks. Security must be built in from day one.

46.5%
Nearly half of developer time goes to building and fixing APIs. Proper design, testing, and documentation upfront frees engineering time for features.

"The backend is the part of your product nobody sees and everybody depends on. Every slow page, every failed transaction, every security incident traces back to a backend decision. Make the decisions right the first time."

Investment Overview
Number of API Endpoints
A backend with 15 endpoints is a focused project. A backend with 80+ endpoints covering a full business domain is significantly more complex.
Authentication & Authorisation Complexity
Basic JWT auth is straightforward. Multi-tenant systems with role-based access, team hierarchies, and permission inheritance add architecture and testing work.
Third-Party Integrations
Each integration (Stripe, SendGrid, Auth0, etc.) requires API client development, webhook handling, error recovery, and testing. Budget 1 to 2 weeks per complex integration.

Frequently Asked Questions
Everything you need to know about this service.
- What is the difference between frontend and backend development?
- Frontend development builds what users see and interact with: buttons, forms, pages, and animations. Backend development builds what runs behind the scenes: the server, the database, the business logic, and the APIs that connect the frontend to the data. The frontend sends requests. The backend processes them and returns responses. Both need to be well-built for the application to work properly.
- How long does backend development take?
- A focused API backend with 10 to 20 endpoints, database setup, authentication, and deployment takes 4 to 8 weeks. A full-featured backend with microservices, complex business logic, multiple integrations, and real-time features takes 8 to 20 weeks. The biggest variable is complexity: the number of resources, the business rules, the integrations, and the testing requirements.
- Should I use REST or GraphQL?
- REST is the default and works well for most applications. It is simple, well-understood, cacheable, and easy to document. Use GraphQL when you have multiple client types that need different data shapes from the same backend, or when your frontend has complex, customisable data requirements. GraphQL adds schema management complexity, so do not use it unless you need the flexibility.
- What database should I use?
- PostgreSQL for most applications. It handles relational data, JSON data, full-text search, and geographic data. It scales to millions of rows without issue. Use MongoDB when your data is genuinely document-shaped without complex relationships. Use Redis as a caching layer on top of your primary database, not as a replacement.
- How do you handle API security?
- Security is built into every layer: JWT or OAuth 2.0 for authentication, role-based access controls for authorisation, input validation on every endpoint, rate limiting to prevent abuse, HTTPS for all communication, and encrypted storage for sensitive data. We follow OWASP API Security guidelines and test for the top 10 API vulnerabilities before deployment.
- What happens if the application needs to scale?
- Your backend is designed for scale from the start: stateless API design, horizontal scaling capability, database connection pooling, caching layers, and load-balanced deployment. When your application needs to handle 10x current traffic, the architecture supports it without a rewrite.
