Check out my new class on the C programming language!

2703.7 EGP /س

C is the most important programming language of the last 50 years. This course is aimed both at absolute beginners and at amateur programmers who wish to become proficient in C. I follow Kernighan and Ritchie's book but I elaborate on the fundamental concepts that underlie the development and runtime environments, e.g. how the compiler works, what the stack is, etc.

Diplômé d'un master en Informatique. J'ai acquis un peu plus de 10 ans d'expérience en tant qu'ingénieur en Informatique.
Je vous propose mes services pour un accompagnement sur mesure sur des thématiques variées autour de l'informatique quel que soit votre niveau.
Les cours peuvent être dispensés à distance et je peux également me déplacer sur la métropole lilloise et aux alentours.
Au plaisir d'échanger avec vous !

I am an engineer by training, PhD in Computer Science, involved in research for 10 years. I supervised many dissertations (TFE, master, and a doctoral thesis). I have done (and still continue) to review articles in renowned scientific journals. I took part in several juries for the evaluation of scientific projects. With a perfect mastery of the appropriate office tools (word, powerpoint, excel, lyx, latex, beamer, slide, etc.), I am available to help you for the smooth running of your project: writing (French/English), structure, proofreading, presentation...
I also worked in higher education for several years, which allowed me to acquire enormous teaching skills.

The course will cover the following points:
- Office automation (Word, Excel)
- Network administration
- CCNA Training (This program provides the foundation for IT professionals who are familiar with the
Cisco networks and operating systems)
- Teaching network courses (LAN, MAN, WAN, TCP/IP protocols)
- Practical work (Packet tracer)
- Some notions on computer security

Do you want to level up in programming, networking, ethical hacking, or IT governance?

I’m here to guide you especially if you’re just starting out and need a clear roadmap to grow and find your place in the IT field. I’ve built a practical learning path for you, with free access to my own platform, where you’ll find well-structured resources to support you at every step.

What’s included:

- Hands-on slides, explained together
- Quizzes to test your knowledge
- Technical projects with my personal guidance

And everything you need to prepare for recognized certifications in the field.

I offer comprehensive training for the Cisco Certified Network Associate (CCNA) exam. In this course, you’ll learn essential networking concepts, including network fundamentals, IP connectivity, IP services, security fundamentals, automation, and programmability. I combine theoretical knowledge with practical skills through hands-on lab exercises and real-world scenarios. Whether you’re new to networking or looking to enhance your skills, this course will prepare you for success in the networking field.

Learn Agent-Based Modeling with a Pro!.

Got a complex system you want to crack? Or just curious about how a bunch of virtual agents can model everything from traffic jams to zombie apocalypses? With 5+ years of teaching bachelor’s and master’s students at TU Delft, I’m here to help you level up your agent-based modeling skills in Python using Mesa library.

We’ll explore how to:
• Simulate traffic jams (so you can finally figure out why your commute takes forever).
• Model epidemics (think less doomsday, more public health superhero).
• Model wealth distribution (yes, even agents argue about who gets the last piece of virtual pie).
• Build eco-simulations where foxes, rabbits, and plants fight for survival.

Whether you’re a total newbie or already know your way around Python, I’ll make the technical stuff simple, the concepts clear, and maybe even throw in a bad joke or two along the way.

Let’s turn your ideas into awesome simulations—and maybe have some fun while we’re at it!
