I've just started my first year studying Computer Science, and I already feel overwhelmed by how much there is to learn. University provides the fundamentals, but I know I'll need practical skills to qualify for an internship after my third year. Because my time is limited by coursework, everyday responsibilities, air raids, and blackouts in Ukraine, I feel pressured to choose a specialization by the end of this year or sometime during my second year.
I'm struggling with several connected questions. How can I explore areas such as frontend, backend, mobile development, DevOps, or data without spending several months on every option? Is frontend still a reasonable path for a beginner despite the competition for junior roles and the impact of AI tools? I'm drawn to frontend because I enjoy creating things with visible results, but I'm worried that the market is already too crowded.
I'm also unsure how to learn effectively in the AI era. AI can generate boilerplate and explain concepts, so I don't know how much coding I should learn manually before relying on it. I have limited money and time, so I would prefer free resources, short practical projects, and perhaps AI-assisted learning rather than expensive courses or lengthy lectures.
How deeply should I study a technology before applying for my first trainee or junior position? What fundamentals should I focus on, when should I start using AI tools, and how can I choose a direction without wasting the limited time I have?

Don’t choose a field based only on online predictions about whether it is “safe” from AI or competition. Pick a manageable area, learn its core concepts, and build things that demonstrate you can solve problems. AI can produce code, but you still need to understand requirements, architecture, debugging, testing, security, and whether the output is actually correct.
You don’t need to memorize every library function or avoid AI completely. First learn enough programming to read and explain code, write small programs, debug errors, and work through a problem yourself. Then use AI to suggest approaches, explain unfamiliar code, generate repetitive pieces, or review your work. Verify everything and try to rebuild important parts without blindly copying them.
For now, a sensible plan would be to spend one semester learning programming fundamentals and basic tools, then spend the next few months building two or three small projects in one area. Those projects will teach you more about whether you enjoy the work than endless comparison between career paths.
One practical approach is to choose an ecosystem and a role instead of chasing every individual technology. For example, you could pick a major cloud platform and explore a role such as data engineering, cybersecurity, or platform operations. Once you understand the underlying concepts and can demonstrate them with projects, those skills can transfer between industries and employers.
DevOps and cloud work can be rewarding, but they usually involve Linux, networking, scripting, version control, deployment, and infrastructure concepts, so they may be easier after you have some programming and systems fundamentals. You don’t have to rule it out; just treat it as a possible longer-term direction rather than something you must master immediately.
Feeling overwhelmed at the beginning is extremely common, so try not to treat uncertainty as proof that you chose the wrong degree. You can make an educated guess about the kind of work environment you want, but you don’t need to make a permanent decision right now.
If you eventually want highly specialized work at a large company, you might explore a focused area such as backend development, data engineering, or security. If you prefer small teams or building complete products, a broader web stack—starting with JavaScript or TypeScript—can be useful. Either way, the early years are partly about discovering what kind of work suits you, not just collecting technologies.
Choose one direction for a few months and build small projects instead of trying to master every field. Your first choice does not lock you into a career, and learning the fundamentals will transfer to other areas later.
That makes sense, but I’m still unsure how much I need to know before applying for a first job. I also don’t have much money or time for long courses, so I’m considering free videos and AI explanations. Is it better to learn coding without AI first, or use it from the beginning while making sure I understand the result?
I initially considered DevOps, but I’ve heard it can be difficult as a first specialization. I’m also worried that entry-level jobs expect experience that beginners can’t get. How much coding should I memorize, and when is it appropriate to use AI for boilerplate without becoming dependent on it?
