I will develop scalable REST API and backend architecture
by Shivam ThakurAgra, Uttar Pradesh· IT & Software Engineering
About
The backend is the part nobody sees until it fails at the worst possible moment. I am Shivam Thakur, a full stack software developer and software engineer in Agra, Uttar Pradesh, and I design and build scalable REST APIs and backend architecture in Node.js and TypeScript that hold up under real traffic.
Clean contracts, sane data modelling, proper authentication, and the kind of logging that lets you find out what went wrong at two in the morning without guessing.
API design done properly
- RESTful resources with consistent naming, status codes and error shapes
- OpenAPI documentation your frontend or mobile team can work against
- Versioning, so improving the API does not break existing clients
- Pagination, filtering, sorting and partial responses as standard
- GraphQL or WebSockets where the use case genuinely calls for them
Architecture and performance
- Database schema design, indexing and query optimisation
- Redis caching, job queues and background workers for slow work
- Rate limiting, request validation and abuse protection at the edge
- Horizontal scaling behind a load balancer, containerised with Docker
- Load testing, so the capacity number is measured rather than assumed
Security and operations
- JWT and OAuth authentication with refresh tokens and revocation
- Role and permission checks enforced in one place, not per endpoint
- Input validation and protection against injection and common OWASP risks
- Structured logging, error tracking, health checks and alerting
- CI/CD pipeline, staging environment and automated database backups
Backend engineering for teams in Agra, Noida and Gurugram
A lot of this work is with product teams in Noida and Gurugram that have a strong frontend and need someone to own the API and data layer properly — or to come in and fix a backend that has stopped coping with its own traffic. Remote engagement is the norm there and it works well: shared repository, pull requests, and a weekly review call.
Closer to home, I build backends for startups and software teams in Agra and across Uttar Pradesh, and for businesses in Agra, Mathura and Delhi that need an API layer so their website, mobile app and internal tools all read from the same source of truth instead of three copies drifting apart.

Frequently asked questions
What does backend and API development cost?
This listing starts at ₹65,000 for a complete API — schema design, endpoints, authentication, documentation and deployment. Larger systems with microservices, queues, real-time features or heavy third-party integration are quoted after an architecture session. Audits and performance rescue work on an existing backend are quoted separately and usually start smaller.
Can you fix an existing backend that has become slow?
Yes, and it is a common engagement. I start with a paid audit — profiling the slow queries, checking indexes, looking at N+1 patterns, caching and connection pooling — then give you a prioritised list with the expected gain for each fix. Usually a handful of missing indexes and one or two query rewrites account for most of the problem.
Will my frontend or mobile team get proper documentation?
Yes. Every API ships with OpenAPI documentation, an interactive explorer, example requests and responses, and a Postman collection. Error shapes are consistent across every endpoint, so client-side error handling can be written once rather than per call.
Do you work with clients outside Agra?
Yes, and backend work in particular is mostly remote. Product teams in Noida, Gurugram and Delhi, startups across Uttar Pradesh, and businesses in Agra and Mathura. I work inside your repository with pull requests and code review, so your team keeps full visibility rather than receiving a black box at the end.
REST or GraphQL — which do I need?
REST for most cases: simpler to cache, simpler to debug, and every client library supports it. GraphQL earns its place when you have many different clients each needing a different shape of the same data, or deeply nested reads that would otherwise mean a dozen round trips. I will recommend based on your clients, not on preference.
How do you handle authentication and security?
JWT with refresh tokens and proper revocation, or OAuth where third-party sign-in is needed. Permission checks live in shared middleware rather than being repeated per endpoint, which is where holes usually appear. Every input is validated against a schema, secrets stay in environment configuration, and the build is checked against the OWASP top ten before handover.
Can the API scale if traffic grows suddenly?
It is designed to. Services are stateless so more instances can be added behind a load balancer, expensive work moves to background queues, frequently read data is cached in Redis, and the database is indexed for the queries actually being run. I load test before handover so you have a real number for what it holds, not a guess.
