How to Become a Modern Backend Developer in 2018: A Step‑by‑Step Roadmap

Modern website development has changed dramatically, and many newcomers feel confused; this article provides a comprehensive roadmap for becoming a modern backend developer.

1. Learn a language

Choose a scripting language; Python is recommended due to its rapid demand growth and abundant job opportunities.

2. Apply what you learn

Practice by building small programs such as implementing common bash commands, scraping Reddit’s /r/programming feed to JSON, saving directory structures as JSON, and automating daily tasks.

3. Learn package managers

After mastering the basics, learn the language’s package manager: pip for Python, npm or Yarn for Node.js, Composer for PHP, RubyGems for Ruby.

4. Standards and best practices

Follow language‑specific style guides (e.g., PEP 8 and Google Python Style for Python) and community conventions for other languages.

5. Security

Read the OWASP guide, understand common security issues, and learn how to avoid them in your chosen language.

6. Build and publish libraries

Publish Python packages to PyPI or Node.js packages to npm, then contribute to open‑source projects on GitHub.

7. Testing

Learn unit testing, integration testing, mocks, stubs, and coverage measurement, and apply them to your code.

8. Test‑driven practice

Write unit tests for all programs, especially for contributions on GitHub, and track test‑coverage metrics.

9. Relational databases

Understand concepts such as keys, indexes, normalization, and tuples; start with MySQL (or MariaDB/PostgreSQL) as the first database.

10. Hands‑on project

Build a simple blog application that includes user registration/login, CRUD for blogs, access control so users see only their own posts, unit/integration tests, and query indexing.

11. Learn a framework

For Python, use Django (or Flask for a micro‑framework); for Node.js, use Express.js.

12. Framework practice

Refactor the blog using the chosen framework and integrate testing code.

13. NoSQL databases

Explore NoSQL options (MongoDB, Cassandra, RethinkDB, Couchbase) and start with MongoDB.

14. Caching

Implement application‑level caching with Redis or Memcached and integrate it into the blog.

15. Create RESTful APIs

Study REST principles (Roy Fielding), design RESTful APIs, and understand that REST goes beyond simple HTTP endpoints.

16. Authentication methods

Learn OAuth, Basic Authentication, Token Authentication, JWT, and OpenID, and understand their differences and appropriate use cases.

17. Message brokers

Understand when to use message brokers; start with RabbitMQ (Kafka is also an option).

18. Search engines

When simple queries no longer suffice, adopt a search engine solution appropriate for your scale.

19. Docker

Use Docker to keep development and production environments consistent, clean, and easily deployable.

20. Web server knowledge

Learn the differences, limitations, and tuning methods of various web servers.

21. WebSockets

Optional but useful for real‑time updates; implement WebSocket support in the blog for live list refresh.

22. GraphQL

Study GraphQL APIs, understand how they differ from REST, and why they are sometimes called “REST 2.0”.

23. Graph databases

Explore graph models for flexible relationship handling; try Neo4j or OrientDB.

24. Continuous learning

Stay open, keep exploring topics beyond the roadmap, and practice consistently; the key to mastery is hands‑on experience.
