Backend & API development services for production-ready systems.

Backend and API development services for production-ready systems. We build secure, high-performance REST APIs, GraphQL services and backend integrations with Python/FastAPI, Node.js and Go — type-safe, fully documented, tested, and deployed with security as a default.

Backend & API development that powers real products

REST APIs

Production-grade RESTful APIs with auto-generated documentation, Pydantic validation, and comprehensive error handling. Ready for frontend consumption from day one.

Microservices

Independently deployable microservices with event-driven communication, service discovery, and health checks. Built to scale horizontally under real load.

🔗

Third-Party Integrations

Connect your backend to payment gateways, CRMs, ERPs, cloud services, and any external API. Resilient integrations with retry logic and circuit breakers.

📊

Data Pipelines

ETL pipelines, background task processing, and data transformation services. Async by default, with Celery or native async workers for heavy workloads.

How we approach backend & API development

01 — Design

API-first architecture

We design the API contract before writing code. OpenAPI specs, data models, and authentication flows are defined and approved before implementation starts.

02 — Build

Iterative development

We build in short cycles with continuous integration. Every endpoint gets unit tests, integration tests, and automated security scanning before merge.

03 — Ship

Deploy with confidence

Dockerized deployments with health checks, structured logging, and monitoring. We hand off a production-ready system with runbooks and documentation.

Frequently asked questions

Backend and API development covers the server-side of your product: authentication, business logic, data persistence, integrations and the public APIs your frontend or other systems consume. We design API contracts first (OpenAPI), implement them with Python/FastAPI, Node.js or Go, and ship them with tests, monitoring and security baked in.
A typical REST API project takes 2-6 weeks depending on complexity. Simple CRUD APIs can be ready in 1-2 weeks. Complex systems with authentication, real-time features, and third-party integrations typically take 4-8 weeks.
Yes. FastAPI generates interactive API documentation automatically via Swagger UI and ReDoc. We also provide deployment guides, architecture diagrams, and developer onboarding documentation with every project.
Security is built into every API we ship. We implement JWT/OAuth2 authentication, input validation, rate limiting, CORS configuration, SQL injection prevention, and follow OWASP API Security Top 10 guidelines. Every project includes a security audit before delivery.
Yes. We handle migrations from Django REST Framework, Flask, or other Python frameworks to FastAPI. We analyze your existing codebase, plan the migration path, ensure zero downtime during transition, and validate that all endpoints behave identically after migration.
