How should I start learning software development from scratch?

If you want a free, structured curriculum, take a look at OSSU’s computer science program. It organizes publicly available courses into something close to a full computer science degree. Alongside the theory, build small projects based on things you actually care about. Even a silly script, such as a recommendation tool, can make the learning process much more motivating.

I’d avoid relying on AI tools at the beginning and spend time understanding the fundamentals yourself. Python is a friendly first language, while C can teach you more about memory, pointers, and how computers work under the hood. Stick with a small number of languages until you’re comfortable solving problems, then branch out based on the kind of work you want to pursue.

Be prepared for this to take a while. Learn consistently, practice by building increasingly useful projects, and don’t expect a job immediately after finishing a few tutorials. The software job market can be difficult, and experienced developers are competing for roles too, so developing solid fundamentals and a portfolio is more valuable than chasing every new tool.

A formal computer science degree or master’s is one possible route, especially if you want a structured education and access to traditional recruiting. It isn’t the only route, but the core topics—programming, data structures, algorithms, operating systems, databases, and networking—are worth learning either way.
