The IT world is like a huge city: streets, professions, directions. Someone writes interfaces, someone builds servers, someone sets up an infrastructure of dozens of services. If you're just starting out, it's important to understand where to turn at the start, because the growth rate and your lifestyle depend on it.
Frontend is everything the user sees
The frontend developer is responsible for the visual part of websites and applications: buttons, forms, animations, smooth transitions. He works with HTML, CSS, JavaScript and modern frameworks like React, Vue, or Angular.
Frontend is about aesthetics, UX and instant results. Each change is visible immediately: you literally "draw" the site with code.
Perfect for those who love design and attention to detail.
Backend — the heart of the application
If the front is the facade of the house, then the backend is the pipes, wires and boiler room. Backend developers create logic and databases, process requests, configure authorization and API. Technologies: Python (Django/Flask), Node.js, Java, Go, PHP and databases like PostgreSQL, MySQL, MongoDB.
Backend is about architecture, logic and reliability. Structure, algorithms and the ability to think systematically are important here.
Suitable for those who like "guts" and solving logical problems.
Mobile - code in your pocket
Mobile developers create apps for Android and iOS. Android is more often written on Kotlin or Java, iOS — on Swift, and for both you can use Flutter or React Native.
Mobile is about convenience and performance. You create things that people actually use every day, from alarm clocks to banking apps.
Perfect for those who want to see the result in action — right on the phone.
Data Science — the power of data
Data scientist analyzes huge amounts of data and builds forecasts: from recommendations in Spotify to predicting market demand. Tools: Python, pandas, NumPy, scikit-learn, TensorFlow.
Data Science is about statistics, machine learning and analytical thinking. You create intelligence that helps businesses make decisions.
Suitable for those who love mathematics and experiments.
QA - bug catchers
QA (Quality Assurance) engineers make sure the code doesn't break. They test the product — manually or using autotests (for example, Selenium, Playwright, Cypress).
QA is about attention and responsibility. It's easier to catch a mistake at the test stage than to fix the production at night 🌙
Suitable for those who like neatness, scripts and want to quickly enter IT.
DevOps — infrastructure wizards
DevOps engineers combine development and operation. They set up CI/CD, containerization (Docker, Kubernetes), monitoring and deployment.
DevOps is about automation and stability. If the servers live without restarts, then DevOps did everything right 💪
Suitable for those who love systems, processes and "hardware" in action.
How to choose a destination?
Try a few: create a website, write a bot, make a mini-game.
Listen to yourself: Are you more into visual, analytical, or systemic?
Don't be afraid to change course: IT is a flexible field. Many started with testing and became developers.
The main thing is to start and not stop.
In the attachment Code you can take courses in Python, JavaScript, DevOps and Data Science from scratch. Kodik will help you choose a direction, collect a portfolio and communicate with other students in Telegram channel.
