Answer to the many questions related to information technology.
Want to know how something works, or how you can prevent something.
You have come to the right place, I can teach you in all areas of information technology.
Below you see several questions to which I can give you a clear and straightforward answer. I can explain this to you at any level and we can go deep where you want it. Is your question not listed? Let me know. There are simply too many questions to write here.

How does the internet work?
How does a computer network work?
What is a DHCP server and how does DNS work?

How do I keep my identity hidden online?
What are cookies?
What does my computer store?
How does the Wehkamp site know that I like those pants?

How does Excel work? and Word? and Powerpoint?
What is a router?
How does WiFi work and can my neighbor on my network?
Do I have a strong password?
What is hacking?
How does a computer virus and ransomware work?
How does a firewall work?
What is blockchain?

I teach at different levels, if you are interested you can always send an email without obligation with your question. We can then make a personal study plan.
My specialization is internet security, but I got there by gaining knowledge within all facets of information technology. From system administration, network management and explaining the various functions in Windows or IOS to repairing the hardware of a PC.
I studied business informatics at the Hogeschool van Amsterdam. Nowadays I live on Curacao, but I can give great lessons via webcam. And through the possible use of team viewer or G + I can show on your computer how to configure a router, for example. Nothing is impossible ;-)

About Me
I am a 'tech junkie' I would love to read about the latest technologies all day and to pass this on to others while automating everything with a Raspberry PI.
Of course that's not possible, but I'm getting close. If I can make someone enthusiastic and convey what I have learned to you then my day is a success.
Enthusiasm is contagious, and a better infection than the virus that keeps us all over the world. Let me infect you with the most beautiful profession in the world, you will not regret it.

Objective: To understand AI without fear, to use it to simplify one's life, to know how to identify digital traps, and to use Word, Excel, etc. without difficulty.

1: Demystifying AI (What exactly is it?)
AI is not a movie robot: Difference between fiction and reality.

How it works (simply): The image of the "giant library": AI has read billions of books and uses them to predict the continuation of a sentence or create an image.

Where is it already present? Spell checkers, Netflix/YouTube suggestions, GPS, and voice assistants (Siri/Alexa).

2: Using AI to make life easier
Conversing with AI (ChatGPT, Claude, Gemini):

Ask him to write an administrative email or a complex letter.

Summarize a long newspaper article or document.

Plan a travel itinerary or find recipe ideas with what's left in the fridge.

AI for creativity and memory:

Generate images to illustrate a birthday card (Midjourney, DALL-E).

Using AI to restore or colorize old family photos.

3: Learning to "talk" to AI (The Art of the Prompt)
The context method: Why "Give me a cake recipe" is less effective than "I am allergic to gluten and I am hosting 4 people, give me a simple chocolate cake recipe".

The expert's role: Learning to tell AI "Act like a travel guide" or "Act like an expert gardener".

4: Precautions and Critical Thinking (The Survival Guide)
"Hallucinations": Understand that AI can make false claims with complete certainty (never take medical or legal advice from AI without verification).

Privacy protection:

Never give sensitive data (social security number, passwords, bank details) to an AI.

Knowing that everything we write to the AI is potentially used to train it.

Spotting "Deepfakes":

How to recognize a doctored image or video (details on the hands, strange reflections, slightly metallic voice).

Verify the information: the golden rule of cross-referencing sources.

5: Ethics and Impacts (To go further)
Copyright: Who owns an image created by AI?

The environmental impact: The water and energy consumption of AI servers.

The future: Will AI replace us or assist us?

Do you want to save time, improve your lessons, and explain complex scientific concepts more clearly using AI tools like ChatGPT?

This course is designed for chemistry and science teachers who want to use AI in a practical, structured, and pedagogically meaningful way — without needing any technical background.

I am a chemist and currently studying for a teaching diploma for upper secondary and vocational education at the University of Bern. I also teach chemistry in German to students from Swiss, German, and Austrian school and university systems, and I have experience applying modern teaching methods in real classrooms.

In this course, I will show you how to use AI tools effectively to support your teaching — not replace it.

We will focus on practical applications such as:
• Creating structured lesson plans in minutes
• Generating worksheets, exercises, and exam-style questions
• Explaining complex concepts (e.g. bonding, equilibrium, thermodynamics) in simple and clear ways
• Designing experiments and classroom activities
• Differentiating content for mixed-ability classes
• Creating summaries, visual explanations, and teaching materials

In addition, I will introduce you to useful scientific resources and databases that can significantly improve your teaching and content preparation, including:
• Finding molecular structures and chemical data
• Accessing reliable information about compounds and reactions
• Exploring protein structures and basic bioinformatics resources
• Introduction to drug-related databases and real-world applications

We will also briefly cover modern teaching approaches in an international context, including:
• Understanding differences between school systems (e.g. Swiss, German, IB/international approach)
• Structuring lessons in a clear and student-centered way
• Selecting effective textbooks and practice materials
• Recommendations based on real teaching experience

This combination of AI tools, scientific resources, and modern pedagogy allows you to create more effective, structured, and engaging lessons.

I use these tools and methods regularly in my own teaching and will guide you step by step, providing practical examples you can directly apply in your classroom.

My goal is to help you teach more efficiently, reduce preparation time, and improve the quality of your lessons.

All sessions are adapted to your subjects, level, and teaching context.

Are you intrigued by the world of cybersecurity? This course is designed to teach you the fundamentals of web penetration testing in an accessible, straightforward, and guided way. You don't need advanced knowledge of networks or systems; we'll cover everything gradually and adapt it to your level. All you need is a desire to discover how internet security really works.

During our sessions, we will move from essential theory to practice. Together we will cover:

- Web Fundamentals: How browsers and servers communicate (HTTP/HTTPS protocols, request and response structure).
- Reconnaissance phase: techniques for gathering information about a target before analyzing it.
- We will understand and exploit common security flaws in a fully controlled manner (SQL Injections, Cross-Site Scripting (XSS), authentication problems...).
- Industry tools used by real auditors (Burp Suite, Nmap, Ffuf...).
- We will not only attack, but we will also look at the logic behind how these flaws are mitigated to protect the applications.

The course is essentially aimed at computer enthusiasts with no prior experience in cybersecurity, as well as web developers looking to understand attacks in order to write more secure code, or even vocational or university students who need a more practical approach.

My approach, as I mentioned, is 100% practical and adapted to your learning pace. All the practice is conducted within an ethical framework, using controlled testing environments, virtual machines, and laboratories, completely within the bounds of the law.

We'll start by tackling small challenges together, and as you gain confidence, I'll guide you to audit intentionally vulnerable applications on your own.

A personalized programming course for all levels, from complete beginner to advanced. The goal is simple: to empower you to truly code by understanding what you're doing. Whether you come with no experience, are preparing for an exam, or are in engineering school, this course adapts to your situation. We teach the fundamentals of programming by applying them to concrete problems that motivate you: creating a program, debugging code, building a small project. No abstract theory at first, but real learning through practice.

I don't start by explaining things, but by presenting you with a concrete problem to solve. As you solve it, you naturally discover the theoretical concepts because they become necessary and logical. During each lesson, you code live while I guide you with strategic questions; I never give you the answers on a silver platter. I regularly check your understanding and adjust the pace according to your progress. We use the language best suited to your goals: Python for beginners or for clarity in algorithms, JavaScript for web development, and Java/C++ for advanced concepts.

You'll learn solid fundamentals: variables, loops, conditionals, functions, and debugging. Depending on your level, we'll delve deeper into data structures, object-oriented programming, advanced algorithms, and complexity analysis. There's no set timeframe: we progress at your own pace, working on projects that truly interest you. My commitment: personalized attention, genuine adaptation to your goals, professionalism, and a real passion for helping you succeed in programming.
