1. Fundamentals of Networks and Systems
Before breaking something, you need to know how it works. In this stage you will learn:
The OSI Model: Understanding how data travels from an application to the physical cable.
Essential protocols: What TCP/IP, DNS, HTTP/S and FTP are and how they work.
Command line: Overcoming the fear of the Linux terminal and the Windows CMD.
2. The Security Triad (CIA)
This is the industry's "Lord's Prayer." A good course will teach you how to protect these three fronts:
Confidentiality: Ensure that only authorized people see the data (Encryption).
Integrity: Ensuring that the information is not altered (Hashing).
Availability: That the systems are active when needed (Mitigation of DoS attacks).
3. Types of Attacks and Threats
This is where the theory gets exciting. You will learn to identify:
Social Engineering: How attackers deceive people (Phishing, Vishing).
Malware: Differences between viruses, Trojans, ransomware and spyware.
Web Vulnerabilities: Basic concepts such as SQL Injection or Cross-Site Scripting (XSS).
4. Defense and Mitigation
It's not all about attack; most of the real work is about protecting:
Using Firewalls and Antivirus: Basic Configuration.
Identity Management: Two-factor authentication (2FA) and biometrics.
Basic cryptography: How public and private keys work.
SIEM Log event management.

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)

Whether you're preparing for IB, IGCSE, GCSE, or simply want to build confidence in Mathematics, I'm here to help. I have over 3 years of teaching experience and 7 years of professional software engineering experience, allowing me to explain mathematical concepts in a clear, logical, and practical way.

My lessons are tailored to each student's needs and learning pace. I believe understanding the "why" behind a concept is far more valuable than memorising formulas. During lessons, I use carefully prepared practice questions and exam-style exercises, many of which I create myself using professional typesetting tools like LaTeX that is used by IB and Cambridge directly.

I encourage students to ask questions freely and develop strong problem-solving skills. Whether you're aiming to improve your grades, prepare for school exams, or study for international curricula such as IB, IGCSE, or GCSE, I'll help you build confidence step by step in a supportive learning environment.

I use a Pen Display Tablet to write on it using Goodnotes as the writing app, which I share the link to the whiteboard used with the students.

Lessons are available online or in-person (within 30 mins train travel from Shinjuku, Tokyo), and are conducted in English.

As a Master's student in Data Science at EPFL, a graduate of CentraleSupélec (ranked in the top 3% of my class) and holder of a Bachelor's degree in microtechnology from EPFL, I offer tutoring in mathematics, physics and computer science, from primary school to university level.
My teaching experience
I was a student teaching assistant at EPFL for 8 courses, working with over 400 students. I currently lead the linear algebra and ICC (Information, Computation, Communication) exercise sessions. Each week, I adapt my explanations to each student's level: that's what I love most about teaching.
What I propose
• Primary and secondary school: consolidate the basics (calculation, fractions, geometry, equations), regain confidence and improve methodology.
• Gymnasium / high school (maturity, baccalaureate): functions, analysis, probabilities, vectors, mechanics, electricity, exam preparation.
• University / EPF / preparatory classes: analysis, linear algebra, probability and statistics, numerical analysis, programming (Python, C/C++).
My method
I begin by identifying the real obstacle: a misunderstanding of the concept, a lack of methodology, or stress. Then, I build the sessions based on the student's lessons and exercises. The goal isn't just to pass the next test, but to understand the material and become independent.
Whether you need occasional homework help, regular support, or intensive exam preparation, I adapt to your needs.

Your application is running on your machine... and then what? Knowing how to containerize and automate deployments has become an expected skill for every developer, and it's often what junior candidates lack during interviews. I'm a full-stack engineer and I implement these pipelines in production (Docker, GitLab CI/CD, GitHub Actions, GCP Cloud Run, Kubernetes). I'll teach you how to do the same, on your own project.

Program (adapted to your level):

Docker basics: images, containers, Dockerfiles, volumes, networks
Docker Compose: Launch a complete app locally (front end + API + PostgreSQL database)
Optimizing your images: multi-stage builds, lightweight images, security best practices
Continuous integration: your first pipeline with GitHub Actions or GitLab CI
Automatic quality control: tests, linting, and formatting are performed with each push.
Build & registry: build and publish your images (Docker Hub, GCP Artifact Registry)
Continuous deployment: put your app online in the cloud (GCP Cloud Run), manage environment variables and secrets
Final project: a complete pipeline, from git push to online application, including database migrations

For who ?

Developers (Node.js, React, Python, PHP...) who want to master deployment
Students and career changers who want a solid project for their portfolio
Teams or freelancers who want to automate their production deployments

Prerequisites: knowledge of how to use Git and having already coded a small application (in any language).

Each session is practical: we work directly on your code, and you leave with a working pipeline.

During lessons, I use carefully prepared practice questions and exam-style exercises, many of which I create myself using professional typesetting tools like LaTeX that is used by IB and Cambridge directly.

I encourage students to ask questions freely and develop strong problem-solving skills. Whether you're aiming to improve your grades, prepare for school exams, or study for international curricula such as IB, IGCSE, or GCSE, I'll help you build confidence step by step in a supportive learning environment.

I use a Pen Display Tablet to write on it using Goodnotes as the writing app, which I share the link to the whiteboard used with the students.

Lessons are available online or in-person (within 30 mins train travel from Shinjuku, Tokyo), and are conducted in English.

I am a certified computer science professor who helps graduates and students with exam retakes and competitions. I tutor preparatory classes (MPSI, MP, PSI, ECS, etc.) up to university level (Bachelor's & Master's in Science or Economics). My method is based on understanding the lessons, practicing correctly, organizing the concepts, and completing exercises and problems of your choice. Each session includes verbal exercises, methodological tips, and subsequent personalized advice. You will receive a video recording and an annotation in PDF format after each session. The online courses are conducted via Google Meet, 5 days a week, with flexible scheduling. I am available between sessions to answer questions. Contact me for an initial consultation.

Want to break into systems, legally? Learn penetration testing from someone who does it for a living.

I'm a cybersecurity engineer with 150+ penetration tests and vulnerability assessments for government, financial, and telecom organizations. I hold CRTP, eWPT, and eJPT certifications, and I'll teach you the same methodology I use on real engagements. No boring theory dumps, just live, hands-on practice.

You'll learn:

The pentesting process: scoping, recon, scanning, exploitation, and reporting
Network and web application testing basics
Common vulnerabilities like SQL injection, XSS, and broken authentication
Core tools: Nmap, Burp Suite, Nessus, Metasploit, and Wireshark
How to document findings and write reports that clients actually act on
How to build a home lab and keep practicing on your own

Perfect for: beginners, students, career changers, developers, IT staff, and anyone preparing for eJPT, PNPT, OSCP, or CEH.

You'll walk away with a clear pentesting workflow, real hands-on skills, and a solid roadmap for a career in offensive security.

Basic computer skills are enough, and networking knowledge is a plus. Book your first session and let's start hacking (ethically)!

As a Master's student in Data Science at EPFL, a graduate of CentraleSupélec (ranked in the top 3% of my class) and holder of a Bachelor's degree in microtechnology from EPFL, I offer tutoring in mathematics, physics and computer science, from primary school to university level.
My teaching experience
I was a student teaching assistant at EPFL for 8 courses, working with over 400 students. I currently lead the linear algebra and ICC (Information, Computation, Communication) exercise sessions. Each week, I adapt my explanations to each student's level: that's what I love most about teaching.
What I propose
• Primary and secondary school: consolidate the basics (calculation, fractions, geometry, equations), regain confidence and improve methodology.
• Gymnasium / high school (maturity, baccalaureate): functions, analysis, probabilities, vectors, mechanics, electricity, exam preparation.
• University / EPF / preparatory classes: analysis, linear algebra, probability and statistics, numerical analysis, programming (Python, C/C++).
My method
I begin by identifying the real obstacle: a misunderstanding of the concept, a lack of methodology, or stress. Then, I build the sessions based on the student's lessons and exercises. The goal isn't just to pass the next test, but to understand the material and become independent.
Whether you need occasional homework help, regular support, or intensive exam preparation, I adapt to your needs.

Your application is running on your machine... and then what? Knowing how to containerize and automate deployments has become an expected skill for every developer, and it's often what junior candidates lack during interviews. I'm a full-stack engineer and I implement these pipelines in production (Docker, GitLab CI/CD, GitHub Actions, GCP Cloud Run, Kubernetes). I'll teach you how to do the same, on your own project.

Program (adapted to your level):

Docker basics: images, containers, Dockerfiles, volumes, networks
Docker Compose: Launch a complete app locally (front end + API + PostgreSQL database)
Optimizing your images: multi-stage builds, lightweight images, security best practices
Continuous integration: your first pipeline with GitHub Actions or GitLab CI
Automatic quality control: tests, linting, and formatting are performed with each push.
Build & registry: build and publish your images (Docker Hub, GCP Artifact Registry)
Continuous deployment: put your app online in the cloud (GCP Cloud Run), manage environment variables and secrets
Final project: a complete pipeline, from git push to online application, including database migrations

For who ?

Developers (Node.js, React, Python, PHP...) who want to master deployment
Students and career changers who want a solid project for their portfolio
Teams or freelancers who want to automate their production deployments

Prerequisites: knowledge of how to use Git and having already coded a small application (in any language).

Each session is practical: we work directly on your code, and you leave with a working pipeline.
