Scalable Node.js backends and REST APIs built for production — not just demos.
A great frontend is only as good as the backend powering it. At CodeTagz, we build production-grade backends using Node.js and Express — the same stack powering companies like LinkedIn, Netflix, and Uber. Our backends are designed to handle real traffic, real data, and real security requirements from day one.
We specialise in REST API design, PostgreSQL database schema design, and building systems that integrate with third-party services — payment gateways, SMS providers, cloud storage, and external APIs. Whether you need a backend for a new web app, a mobile app, or to replace a legacy system, we deliver clean, documented, deployable code.

01
Database design is where backend quality is determined. We model your entities, relationships, and constraints carefully before writing server code.
02
We document every endpoint — method, path, request body, response shape, and error codes — before writing a line of server code. This eliminates integration surprises.
03
Authentication, input validation, rate limiting, and security headers are implemented from the start — not bolted on later.
04
We test each endpoint and provide a Postman collection or API documentation so your frontend team or future developers can integrate immediately.
Why It Matters
01
One backend powers both your web application and mobile app. Build once, serve everywhere — consistent data, consistent behaviour.
02
Rate limiting, CORS policies, Helmet headers, input validation, and parameterised queries prevent the most common attack vectors.
03
Proper indexing, connection pooling, and query optimisation mean your database stays fast even as your data grows.
04
Your backend comes with API documentation and clear code structure so you or any developer can understand and extend it.
From Our Work
Our backends power Guiding Verses, StreamVault, NewsByte, and TopicsCorner — different products, same quality of architecture.
FAQ
Yes. We can build a backend API to connect to an existing React, Next.js, or React Native frontend. We'll need to align on the API contract first.
Yes — we can work with an existing PostgreSQL database, or build migrations to move from MySQL or MongoDB to PostgreSQL if required.
We use Multer for file handling and store files in Cloudflare R2 or AWS S3. Files are served via CDN for performance.
Yes — we can implement WebSocket-based real-time features (chat, live notifications, dashboards) using Socket.io or Server-Sent Events depending on the use case.
A standalone REST API backend typically costs ₹50,000–₹2,00,000 depending on complexity. We quote a fixed price after understanding your requirements.
