📌 Is seniority just years of experience?

Many people think "3 years and I'm a middle, 5 years and I'm a senior". In reality, seniority is measured not by time but by the scope of responsibility. A junior completes an assigned task, a middle solves a task independently, and a senior identifies the problem itself and shows the team the way to a solution.

Habits that speed up growth 💡

First — ask for tasks slightly above your level: there is no growth in the comfort zone. Second — be active in code review: reading other people's code is one of the fastest ways to learn. Third — be able to explain your code: if you can't say why this particular solution was chosen, you haven't understood it deeply.

Fourth — beyond technology, pay attention to communication. Half of a senior developer's job is with people: clarifying requirements, defending solutions, mentoring others.

Patience and consistency 🚀

Growth is not linear: for months it feels like nothing is changing, then you suddenly notice you've reached a new level. The key is to keep going. It's not hard to imagine where a developer who learns one new thing every day will be in five years.
