Spend some days researching the possible fields. when you find the one you like, study the tech that surrounds that from the fundamentals. STICK with ONE language until you are good with it. My biggest mistake was to keep switching programming languages. Also, choose a field you like, if you do it solely for money, you can do it too, but it will be a pain. If you like low level, stick with this shit, if God gave you the grace to love Java, stick with that. If you love data, Python, etc. If you like cloud, devops, Golang, etc. The most important thing is you need to have fun while learning, and you need to focus on small things every day until they become big! The market is not good, but it will be better, just do the best you can.

With 3 year gap, you need to try to catch up how the things are, watch tutorials etc, see what people are doing differently from 3 years ago (tbh, it's not that different, they talk about AI slop now).

For example, React is still widely used for the frontend, angular for enterprise still sometimes, and vue with laravel a lot of the time. And java, C#, Go, and Node.js with TypeScript are still widely used for the backend. Rust (few jobs) is in ascension too for systems with C/C++, etc. C++/C# for games and now Godot with GDScript (few jobs). A lot of people focus on architecture, system designs, performance now too because of AI.

You can also go AI if you like math a lot. For generative AI, be careful with advices it gives you, also if the code you are generating on AI is not mundane for you, I believe its not a wise choice to generate it. Unless you spend time reading and evaluating everything. Because that can actually make you dumber. Just make sure you understand the code, its like copy pasting from stack overflow without understanding in steroids haha.
