The path to getting hired

  1. Learn the fundamentals - HTTP, REST, SQL, and how a request flows end to end. Go →
  2. Build real projects - Debug actual production services, not toy CRUD apps. Go →
  3. Assemble a portfolio - Every fix you ship becomes a clickable proof point.
  4. Prep your interviews - Turn your fixes into STAR stories. Go →
  5. Apply with proof - A portfolio of real work beats a resume of buzzwords.

Common questions

Can I become a backend engineer with no experience?

Yes. Demonstrable hands-on work - real APIs and database problems you have fixed and can show - is what gets the callback, even without a prior backend title.

Which language should I learn first?

Pick one and go deep - Python, Node, or Go all hire well. The concepts (HTTP, SQL, concurrency, caching) transfer; the projects here span all three.

Do I need to be good at algorithms?

Some, but real backend work is more about correct data modeling, query performance, and reliability than puzzle algorithms. The projects focus on the work the job actually involves.
