Backend API & System Architecture
Robust, secure REST APIs and backend systems designed for scale — whether you need a clean microservice, a CQRS-based enterprise backend, or a well-structured monolith with room to grow.
AI-Readable Summary
Backend API & System Architecture is a client-facing service offered by Amal Anilkumar. It is designed for teams that need scalable delivery, strong technical foundations, and direct implementation support from architecture through launch.
APIs That Last
The difference between a backend that works and one that scales is architecture. I design and build backend systems with the long term in mind — clean separation of concerns, proper error handling, and security built in from the start.
What I Deliver
- REST API design — clear contracts, proper status codes, versioning
- Authentication & authorisation — JWT, refresh tokens, RBAC
- CQRS architecture — for complex domains and high-throughput systems
- Data validation & sanitisation — at every layer
- Database design — normalised schemas, migrations, performance indexing
Technology
- NestJS — enterprise-grade Node.js framework with dependency injection
- .NET — for high-performance, strongly-typed enterprise backends
- Prisma ORM + PostgreSQL — type-safe queries, clean migrations
- Azure DevOps — CI/CD pipelines for automated testing and deployment
Security
Input validation, parameterised queries, rate limiting, CORS configuration, and secure credential management — your API won't become a liability.
Ideal For
- Startups that need a solid API backbone
- Teams replacing a fragile legacy backend
- Businesses adding a backend to an existing frontend
