While adults are still debating whether kids should use AI, they are already using it.
The question isn't "should they?" it's "how do we do it intelligently?"

In this course, your child will discover:
✓ What AI actually is: not magic, not mystery. How machines think, what they can do, what they can't
✓ How ChatGPT really works: not just "ask a question and get an answer," but why it responds that way, where it fails, when to trust it
✓ What LLMs are (Large Language Models): in language they understand, not tech jargon
✓ Create with AI: custom avatars, interactive stories, real projects using real tools
✓ Think critically about AI: Bias, privacy, creativity. What does AI do better than humans? What can't it do?
✓ Real-world applications: How AI transforms medicine, education, art, gaming, everyday life

Why this is different:
Most AI courses for kids teach "here's the tool, use it." I teach how to think about AI.
Your child will learn to see AI not as black magic or a solution to everything, but as a powerful tool with real limits.
And, more importantly: that they can control how they use it.

What they take home:
Real projects they created (custom avatar, interactive app, analysis of a real AI case study). A genuine understanding of how it works. And the ability to use AI responsibly and creatively.

Format: Online | 60–90 min sessions | Flexible, adapted to their age and pace

For curious kids asking "How does ChatGPT actually know things?"

Ever wondered what really happens when you open a website or hit "send"? Let's find out together.

I've spent 3 years working hands-on with real networks: analyzing live traffic, managing firewalls, and troubleshooting network issues for government, financial, and telecom organizations. I'm Fortinet certified (FCA, FCF) and hold the CNSP (Certified Network Security Practitioner) certification. I'll teach you networking the way it's actually used on the job. No boring theory dumps, just live, hands-on learning you can use right away.

You'll learn:

How the internet works: IP addresses, DNS, DHCP, and HTTP/HTTPS
The OSI and TCP/IP models, made simple
Subnetting, routing, switches, and firewalls
TCP vs. UDP, ports, and how connections work
How to read real traffic with Wireshark and test networks with ping, traceroute, and Nmap
How to spot suspicious traffic and keep a network healthy

Perfect for: beginners, career changers, students, developers, and anyone preparing for Network+ or CCNA.

You'll walk away with a clear picture of how data travels, the confidence to troubleshoot real network problems, and a rock-solid foundation for your IT career.

No experience needed, just curiosity and a computer. Book your first session and let's dive in!

Most cybersecurity courses skip the part everything else sits on: how Linux, processes and memory actually behave. You're expected to "just know" it. I teach that part, one to one, at your pace.

Who I am: a backend team lead with 7+ years in production, and a CTF player. My team placed 9th of 200+ at Standoff 15, a three-day live offensive-security competition, and I've published Hack The Box writeups and a malware analysis. I also mentored groups of 14-17 students at LANIT-Tercom's developer summer camps in 2021 and 2022.

What we can cover (you pick):
- Linux fundamentals: shell, files and permissions, users, processes, services, logs, package managers
- Linux for security: what attackers and defenders actually look at on a box
- How computers work: boot, CPU and memory, processes and threads, syscalls, file systems
- Your first TryHackMe / Hack The Box machines, coached step by step (legal platforms only)
- Privacy basics: threat modelling, passwords and 2FA, what a VPN does and doesn't do
- "I'm stuck on this uni topic": concepts explained, not answers handed over

How lessons work:
1. You tell me what you want to understand or what you're stuck on.
2. We share a screen and you drive. I ask questions, point and explain. I only take the keyboard to show something, then hand it back.
3. After the lesson you get a written recap: what we covered, commands, links and one small task for next time.

I won't do graded homework for you. I'll make sure you understand it well enough to do it yourself.

Good fit for: cybersecurity and CS students, self-taught people moving into security who keep hitting gaps in the basics, and developers who want to stop being scared of the terminal.

Send me a message with what you're working on and we'll plan your first lesson around it.

FIRST CLASS
In the first class, we'll discuss your goals, assess your current level, and answer your most pressing questions. From there, we'll design a personalized learning plan, outlining the topics, pace, and frequency of your classes. You'll leave the first session with a clear path forward and some initial learning.
