Backend & API Engineering

API Development Company in India

APIs built to be a stable foundation for your product — documented, authenticated properly, and rate-limited from day one, not retrofitted after an incident.

The Backend Work That’s Invisible Until It Breaks

A good API is mostly invisible — nobody notices authentication, rate limiting, or clean documentation when they’re working correctly. They become very visible the moment they’re missing: a security incident from weak auth, a partner integration stalled because the API isn’t documented, or a single bad actor taking down your service because there’s no rate limiting.

We build RESTful and GraphQL APIs with JWT/OAuth2 authentication, rate limiting, and OpenAPI/Swagger documentation as standard practice, not optional extras — whether the API powers your own frontend, a mobile app, or external partner integrations.

What We Build

OpenAPI / Swagger documentation

Generated and kept current, so integrating teams aren’t reverse-engineering your API from example requests.

JWT & OAuth2 authentication

Industry-standard auth implemented correctly — not a custom token scheme with subtle security gaps.

Rate limiting & abuse protection

Built in from the start, so one bad actor or buggy client can’t take down the service for everyone.

Sub-20ms latency targets

Query and caching strategy designed for speed, checked against a real latency target before launch.

Technology Stack

Node.js
Express
Laravel
PHPPHP
PostgreSQL
Typical timeline: 3 – 6 Weeks for a scoped API; longer for a large multi-service backend

Our Process

01
API design & contract

Endpoints, auth flow, and data contracts are designed and documented before implementation starts.

02
Core build

Authentication, rate limiting, and core endpoints are built against the agreed contract.

03
Documentation & testing

OpenAPI docs are generated and the API is load-tested against a real latency target.

04
Integration support

We support your team or partners through their first real integration, not just a handoff document.

Pricing Approach

API projects are priced by endpoint complexity and integration count, not a flat day rate — billed in milestones like our other engagements.

Frequently Asked Questions

REST suits most straightforward CRUD-style APIs; GraphQL earns its complexity when clients need flexible, nested data fetching. We recommend one based on your actual client needs, not a default preference.
Yes — we design the API contract around your existing client’s real data needs, not a generic schema.
Yes — JWT/OAuth2 authentication, rate limiting, and standard security practices are built in as a default, not an upsell.
Yes — OpenAPI/Swagger documentation is standard deliverable, not an optional add-on.
