Scalable API & Cloud Backend Architecture Agency India
High-concurrency Node.js, Express, PostgreSQL, and SQLite backends built for performance, security, and zero-downtime reliability in India.
Direct Engineering Execution for API & Backend Architecture
A great frontend is only as reliable as the backend supporting it. We design, build, and optimize secure backend systems, database schemas (PostgreSQL, SQLite, MongoDB), authentication pipelines (JWT, OAuth), payment gateways (Stripe, Razorpay), and scalable API endpoints ready for high traffic.
Core Technical Deliverables
- Node.js & Express RESTful & GraphQL API development
- PostgreSQL, SQLite WAL, and MongoDB database modeling
- Role-based access control (RBAC) & JWT security
- Payment gateway integrations (Stripe, Razorpay, UPI)
- Real-time WebSocket & Socket.IO communication pipelines
- Rate limiting, error handling, & security header hardening
- Graceful shutdown & production health check diagnostics
- Cloud deployment (AWS, Vercel, VPS with PM2)
How We Deliver API & Backend Architecture
Disciplined 4-stage execution from scope lock to production deployment.
Schema & Architecture Design
We design your data models, endpoint specifications, and authentication flows before writing backend code.
API Implementation
Clean, modular Express/Node.js architecture built with strict validation, error handling, and security.
Database & Security Hardening
Indexing, migration scripts, rate limiting, and JWT authentication pipelines thoroughly load-tested.
Deployment & Monitoring
Configured with environment variables, health checks, PM2/cloud infrastructure, and zero-downtime deployment pipelines.
