A computer programmer turns specifications into working, tested, documented code, and then keeps that code healthy as needs change. This roadmap takes you from your first program to being hired to owning complex systems. Programming is learned by writing a lot of code and fixing your own mistakes, so every stage ends in a project you can show an employer. About 88% of people in this job hold a bachelor's degree, but a strong public portfolio, solid fundamentals and clear communication can open doors for you too, especially at smaller companies and for apprenticeships. You can do this: go one s

Stage 1 of 3 · about 10 weeks
Write, run, and debug small programs in one language, and use Git to save your work.
Core programming in Python
Every program is variables, decisions, loops, and functions. Python reads almost like plain English, so you can focus on logic, which is the heart of the job (O*NET: 'symbolic logic'), instead of fighting syntax.
Debugging and testing
Much of a programmer's day is finding why code does not do what you expected. A calm, repeatable method beats guessing, and it is the core task 'correct errors and recheck the program'.
Git and GitHub basics
Employers expect version control from day one. It lets you undo mistakes, work with others, and show your work publicly.
Logic and basic math for code
Boolean logic, modulo, and simple algebra come up constantly in conditions, loops, and data handling. O*NET lists mathematics as a top skill for this role.
Command line basics
Servers, build tools, and scripts all run from a terminal. Being comfortable there makes everything faster.
Then 2 more stages (about 54 weeks in all) with lessons, drills, projects, 6 interview questions with strong answers and free resources.
