Become a production-ready backend developer. Master APIs, databases, authentication, and deployment. This roadmap is sourced from the best free resources curated for Indian learners.
Pick one language — Python or JavaScript — and master it deeply. Learn variables, functions, loops, data structures, and OOP. Everything else in backend development builds on this foundation.
By the end, you'll be able to
Mini-project
Build a CLI task manager that reads/writes to a JSON file. Add CRUD operations, due dates, and priority sorting.
Data is the core of every backend. Learn SQL deeply: queries, joins, indexing, normalization, and transactions. Start with MySQL or PostgreSQL — they power most production apps in India.
By the end, you'll be able to
Mini-project
Design the database for a food delivery app (users, restaurants, items, orders, payments). Write 20 queries: top restaurants, revenue per month, user order history, etc.
Learn how to build a web server. Understand HTTP, request/response, routing, middleware, and how to structure a backend project. Pick Express (Node) or Flask/Django (Python).
By the end, you'll be able to
Mini-project
Build a bookstore API with Express or Flask. Implement CRUD for books, search by author/genre, pagination, and input validation. Test every endpoint with Postman.
Learn to design proper REST APIs: resource naming, HTTP methods, status codes, pagination, and error handling. Then add auth: JWT tokens, bcrypt password hashing, and session management.
By the end, you'll be able to
Mini-project
Add user registration, login, and protected routes to your bookstore API. Use JWT tokens, hash passwords with bcrypt, and add role-based access (admin vs user).
Every backend team uses Git. Learn branching, merging, pull requests, and collaborative workflows before your first job — interviewers expect this.
By the end, you'll be able to
Mini-project
Contribute to an open-source backend project on GitHub. Start with docs or a small bug fix. Getting a PR merged is the best resume line.
Not everything fits in tables. Learn when to use NoSQL, document modeling in MongoDB, aggregation pipelines, and how to choose between SQL and NoSQL for a given problem.
By the end, you'll be able to
Mini-project
Build a chat app backend with MongoDB: users, conversations, messages. Use the aggregation pipeline to get unread counts and recent conversations.
Production code needs tests. Learn unit testing, integration testing, mocking, and how to write tests that catch real bugs instead of just hitting coverage numbers.
By the end, you'll be able to
Mini-project
Write a full test suite for your bookstore API: happy paths, edge cases, auth failures, and database errors. Aim for 80%+ coverage.
Ship your code. Learn Docker containers, environment variables, CI/CD pipelines, and how to deploy to AWS/Vercel/Railway. A project that isn't deployed doesn't exist.
By the end, you'll be able to
Mini-project
Dockerize your bookstore API, add a GitHub Actions CI pipeline, and deploy to Railway or AWS EC2 with a managed database. Set up environment variables properly.
Understand how real systems scale. Learn about load balancers, caching (Redis), message queues, microservices vs monoliths, and database scaling strategies.
By the end, you'll be able to
Mini-project
Draw the architecture for a URL shortener like bit.ly. Then build it: API, Redis cache, analytics tracking, rate limiting. Deploy it.
Backend interviews in India test: DSA (medium LeetCode), system design, SQL queries, API design, and sometimes a take-home project. Practice daily and build a portfolio of deployed projects.
By the end, you'll be able to
Mini-project
Do 3 mock system design interviews on Pramp or with a friend. Solve 50 LeetCode problems (focus on arrays, strings, trees, graphs). Apply to 20+ companies.
