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.

Are you using ChatGPT, Gemini, or other AIs, but feel like you're only scratching the surface of their potential? Are your results often generic, inaccurate, or disappointing? It's time to move from a simple user to a true AI pilot. 🤖✨

This 4-hour intensive course, "Prompt Engineering: Mastering the Art of Communicating with AI," is designed to give you the keys to effective and powerful communication with language models (LLM).

> 🧠 “If I had an hour to solve a problem, I would spend 55 minutes defining the question.”

This is the essence of Prompt Engineering: the art of asking the right question to get the best answer. 🎯

🧰 Exclusive methods taught

During this practical and immersive training, you will discover two structured methods to transform your ideas into tangible results:

🔹 The ACTIF method
👉 A foolproof approach to building powerful text prompts. You'll learn how to define:

Action
Context
Tone
Identify
Format

...in order to obtain clear, targeted and impactful content, analyses or strategies. 📄💡

🔹 The IMAGES method
👉 Your visual passport to create high-value graphic prompts. Based on 6 pillars:

Intention
Pattern
Atmosphere
Grain
Aesthetic
Style

...it will allow you to generate images that faithfully reflect your creative vision. 🖼️🎨

👥 Who is this course for?

✅ Entrepreneurs and marketers who want to create targeted content and relevant strategies.
✅ Content creators, writers, designers who want to boost their creativity and productivity.

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?

Learn Arduino, robotics and electronics one to one with a qualified electronics engineer who teaches this at university level. Complete beginners through to degree students, online worldwide or in person in Birmingham, with a free 30 minute introduction before you book anything.

I'm Ghous. I hold an MSc in Electronics and Electrical Engineering with Distinction from the University of Chester, where I teach as a Visiting Lecturer on a Master's module, and I work as a freelance engineer designing circuit boards and writing embedded firmware for clients. I have taken a four layer ESP32 board from schematic to manufactured hardware, built the electrical power system for a CubeSat, and published two international conference papers on running neural networks on microcontrollers. When you ask why your sensor reads nothing or how to justify a design choice in a report, the answer comes from doing this work rather than from a tutorial.

Adults and hobbyists

If you own an Arduino kit and have stalled, or you can copy a project but cannot change it, this is the gap I close. We build what you actually want, home automation, data logging sensors, motorised builds, a device that talks to your phone, and underneath it you pick up the real skills: reading a datasheet, using a multimeter, wiring safely and debugging when nothing happens. No technical background required.

University and college students

Embedded systems, microcontrollers, robotics, control systems, circuit analysis and digital electronics. Arduino, ESP32, nRF52, PIC with MPLAB and STM32, plus Proteus, Multisim, Webots and PCB design in KiCAD. I also supervise final year and Master's projects from scoping through to the write up. I mark Level 7 work myself, so I know where reports lose marks. I teach students on UK, IB and continental European programmes and have worked with engineering students in Germany, so an unfamiliar syllabus is not a problem. Send me your course material and I will work from it.

School students, ages 9 to 18

Beginners who want to build something real, and students with coursework in Design and Technology, Computer Science or Engineering, whether on GCSE, A Level, IB or a national curriculum. Typical builds are a line following robot, an obstacle avoiding car, a live weather station or a motion triggered alarm. For lessons in Birmingham I bring all the equipment. Parents are welcome to sit in on the first session (UK DBS checked).

How lessons run

Tell me your level and what you want to build, or send your assignment brief, and I plan the session around it before we meet. I demonstrate first, then you take over while I guide, because nobody learns electronics by watching. Online students share a screen and I debug code and wiring photos live. Every session ends with something working and a clear next step, and you can message me between lessons.

Lessons run over Google Meet or Zoom, 60 or 90 minutes. I teach across GMT and Central European time with evening and weekend slots. Online students can start with any board they already own, or I will point you at one starter kit under 30 euros that covers the first several months.

Message me with your level and what you are trying to build and we will arrange the free 30 minutes.
