How to become a developer?

Before diving in, learn what these specialists do, their typical responsibilities, and the types of projects they work on. This helps you identify which area interests you most.

You can learn software development skills through various avenues, including:

  • Formal Education. Obtain a degree in computer science, software engineering, or a related field. While not always required, it provides a solid foundation in programming, algorithms, and data structures.
  • Bootcamps. Enroll in intensive coding bootcamps to explore specific programming skills in a shorter timeframe.
  • Self-Study. Use free or paid online resources like tutorials, videos, and books to study independently.

Start with beginner-friendly programming languages such as:

  • Python: Easy to learn and widely used.
  • JavaScript: Essential for web development.
  • Java: Common in enterprise applications.

Practice by creating real-world projects such as:

  • A personal portfolio website.
  • A to-do list application.
  • A weather app using APIs.

Projects showcase your skills and provide hands-on experience with debugging, version control (Git), and deployment.

Create a portfolio to display your projects and skills needed for software developer. Apply for internships or entry-level roles to gain real-world experience. Work on freelance platforms like Upwork or Fiverr to build a client base and gain experience.

Prepare for coding interviews by practicing problem-solving on services like LeetCode, HackerRank, or Codewars.
