Node.js Backend Development: APIs and Integrations for Your Product
A server side that holds the load and doesn't fail: APIs for applications, external service integrations, databases and background jobs.
A backend is the server-side logic of a product: the API applications talk to, integrations with payments and CRM, data storage and processing, background jobs. We design and build backends in Node.js — from the database schema to a documented, tested API.
We write in TypeScript: types at API boundaries catch errors before production. For each task we pick the right tool — REST or GraphQL, PostgreSQL or SQLite, queues or streams — and explain the choice in plain language.

What you get
- 01Data designDB schema, migrations and indexes for your queries: data stays consistent, lookups stay fast, changes stay safe.
- 02Integrations and webhooksPayment systems, CRM, mailings, maps and external APIs — with retries, idempotency and logging.
- 03SecurityInput validation, access control, rate limits and protection from common attacks — checked against OWASP checklists.
- 04PerformanceCaching, queues and background jobs: heavy operations never slow down API responses.
- 05Documented APIAn OpenAPI schema and clear docs: frontend and mobile teams plug in without telepathy.
- 06ObservabilityLogs, metrics and alerts: we learn about problems from monitoring, not from customers.
How we work
- 1
Analysis and planning
We define the domain model, data flows and load and security requirements.
- 2
Prototyping and design
We design the DB schema and the API contract, and fix them in documentation.
- 3
Development
We implement endpoints, integrations and background processes, covered with tests.
- 4
Testing
Load testing, security review, monitoring setup.
- 5
Launch and support
Deploy, CI/CD and documentation handover; support under contract.
