FAQ

Common questions about this CV

Do I need a CS degree to become a Backend Engineer?

No. A solid GitHub and the ability to solve problems and explain architecture in interviews matter far more. Some banks and large enterprises still ask, but even there it rarely blocks a hire.

Which language should I pick for backend in 2025?

Python and Node.js have the most junior and mid-level openings. Go is growing fast in fintech and infrastructure. Java still dominates banking and enterprise. Pick what you actually enjoy writing, you'll be using it for years.

How many portfolio projects do I need for my first backend job?

Two or three production-quality projects with tests, CI/CD, and a clear README beat fifteen half-finished repos. Recruiters spend about 30 seconds on your GitHub, and that's enough to see engineering taste or the lack of it.

Do I need Kubernetes knowledge at the mid level?

Basic understanding, yes. You should be able to deploy a service and read pod logs. Deep kubectl skills are usually expected at senior or DevOps level. Docker, however, is non-negotiable today.
