Who Is DevOps Engineer? ⚙️

DevOps engineer = the one who connects developers and deployers

What they do:
👉 Setting up the server and infrastructure
👉 Automating deployment process (CI/CD)
👉 Monitoring applications (performance, bugs)
👉 Making systems scalable and reliable

Tools used:
• Linux
• Docker, Kubernetes
• CI/CD services
• Cloud platforms (AWS, Azure, GCP)

⚠️ This is NOT for beginners

Requirements:
• Good knowledge of back-end
• Basics of networking
• Knowledge of system architecture

Should you go into DevOps?
👉 Yes if:
• You like systems, not UI
• You enjoy automation
• You want high-demand skills

👉 Maybe not if:
• You’re just starting
• You prefer visual work

VS Code vs IntelliJ 💻⚔️

🟦 VS Code:
👉 Super fast & light
👉 Free & open-source
👉 Incredible extensions market
👉 Ideal for web development

🟪 IntelliJ:
👉 Full-fledged IDE
👉 Smart code completion
👉 Ideal for Java/Kotlin, back-end development
👉 Includes many features out-of-the-box (debugging, database support, testing)

Which one to choose?

👉 VS Code:
• You're a beginner
• You're doing web development
• You need speed & simplicity

👉 IntelliJ:
• You're working with Java/Kotlin
• You want an IDE with all features out-of-the-box
• You're working on complex projects

VS Code is a flexible editor
IntelliJ is a powerful IDE

What is JavaScript? 💻⚡

If you are on the Internet... you have JavaScript.

JavaScript = the language of the Web 🌐

What JavaScript does:
• Enables interactivity on websites
• Manages events, form submissions, animations
• Refreshes content without reloading the webpage

Where JavaScript can be found:
• Frontend (browser environment)
• Backend (Node.js)
• Mobile applications (React Native)
• Even desktop applications

Why is it so popular?
👉 Executes in EVERY browser
👉 One of the most in-demand skills

Is it worth learning JavaScript?
👉 YES if you are planning to develop websites or mobile applications
👉 YES if you aim for a career in tech

Without JavaScript, there would be no web development

Why Practice > Courses 💻

Courses are productive.
But they will not turn you into a developer.

Check it out 👇

1. Courses = theoretical

You don't gain any experience

2. Practice = hands-on

You create code
You make mistakes
You correct them

3. Tutorials fool you

Nothing is wrong on the screen. But in real life, everything fails at the first attempt

4. The more you practice, the better you learn

One project = ten tutorials

5. Companies are interested in your projects, no your courses

What is C++? ⚙️

C++ = Enhanced C with additional functionalities

What is C++?
• Programming language optimized for efficiency
• Runs closer to the hardware level
• Best used in high-speed applications

What makes it powerful?
• Highly efficient processing
• Manual memory management
• Class-based programming

In what cases is C++ applied?
• Video games
• Operating systems
• Embedded software systems
• Performance-driven applications

What makes it difficult?
• Difficult syntax
• Manually managing memory allocation
• Sloping learning curve

👉 Learn C++, if you:
• Interested in the basics of computing
• Interested in developing video games

👉 But... maybe, later on, if you are new to programming

Linux VS Windows for Developers 💻⚔️

🟩 Linux:
• Strong terminal
• Closer to server environments
• Lightweight and fast

🟦 Windows:
• Easier to get started with
• Good app/game support
• Zero configuration needed
• WSL: Linux on Windows

Linux:
👉 You’re in charge of everything
👉 You also need to solve everything

Windows:
👉 Everything just works
👉 Less flexibility

Which one to choose?
👉 Choose Linux if:
• You’re focused on backend/DevOps
• You enjoy experimenting and understanding systems

👉 Choose Windows if:
• You’re a beginner
• You value ease of use
• You use your PC for other tasks

Should You Learn TypeScript?👩‍💻

TypeScript = JavaScript + types

It will help you:
• Find bugs in advance
• Get the hang of the code faster
• Develop predictable logic

❓If TypeScript makes sense for you:
• The scope of your project grows
• You cooperate with other developers
• You revisit previously written code and can’t figure anything out

Should you learn it?
👉 YES IF:
• You’ve got basic knowledge of JavaScript
• You plan to work on a serious project
• Your career goals involve IT

👉 NO IF:
• You’re a beginner
• You struggle with JavaScript basics

Guys 👨‍💻, I’ve recently come to realise that writing code is only 30% of the game. The real trick is to make a high-end product out of your tech stack that people really need.

I’m kicking off a new experiment: moving beyond ‘tutorial hell’ and basic pet projects into building real-world, commercial solutions.

I’ll be sharing the technical side of this journey on my Instagram: how to adapt your skills for premium business needs, how to build high-converting UI components, and the process of scaling as a developer. If you want to see the ‘behind the scenes’ of this transition, join me here:

Is Backend Right For You? 💻

What is backend?
👉 Server-side scripting
👉 Database management
👉 Application programming interfaces
👉 Security

Why backend is so good:
👉 High demand
👉 Low competition compared to frontend
👉 Great problem-solving skills
👉 Can be used anywhere in tech

Backend is for you if:
👉 You love systems and logic
👉 You enjoy finding solutions to problems
👉 You're okay without any graphics/UI
