My name is Houssam. I represented Morocco twice at the International Olympiad in Informatics (IOI), and I’ve been deeply involved in programming for over a decade.

What you’ll learn:

- Algorithmic thinking and problem-solving

- Python and C++ programming (from beginner to advanced)

- Preparation for coding competitions (Olympiads, technical interviews)

- Clean coding practices and development logic

Each lesson is tailored to your current level and goals, with a focus on clarity, depth, and measurable progress.
Perfect for those who want to learn programming seriously, sharpen their skills, or prepare for competitive exams.
Teaching that is rigorous, clear, and motivating.

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?"

Your project is broken? Deadline approaching? Can't deploy? I help developers and students fix bugs, optimize code, and deploy applications to production.
I Specialize In:

Emergency Debugging: Find and fix errors fast (frontend crashes, backend timeouts, database issues)
Deployment Rescue: Get your app live when nothing works (AWS, Vercel, Netlify)
Performance Optimization: Speed up slow applications (database queries, API responses, bundle size)
CI/CD Setup: Automate your deployment pipeline (GitHub Actions, testing, monitoring)

Common Problems I Solve:

❌ "My app works locally but crashes in production"
❌ "Database queries are too slow"
❌ "Authentication isn't working"
❌ "Can't deploy to AWS / Vercel"
❌ "Getting weird errors I don't understand"
❌ "Payment integration (Stripe) not working"

Technologies I Work With:

Frontend: React, Next.js, TypeScript, Vue, Angular
Backend: Node.js, NestJS, Express, Python (Django, Flask)
Databases: PostgreSQL, MySQL, MongoDB, Redis
Cloud: AWS (EC2, RDS, S3), Vercel, Netlify, Render
DevOps: Docker, CI/CD, GitHub Actions, Nginx

Perfect For:

Students: Fix your project before the deadline
Junior Developers: Debug production issues you can't solve alone
Freelancers: Get unstuck on client projects fast
Startups: Fix and deploy your MVP without hiring a full-time engineer

How It Works:

Live Debugging Session: We fix it together via screen share
Code Review: I show you how to prevent the issue in the future
Documentation: You get a summary of what was fixed and why

Average Resolution Time:

Simple bugs: 1-2 hours
Deployment issues: 2-3 hours
Complex debugging: 3-5 hours

Urgent projects accepted (same-day availability for emergencies).

After an initial assessment, this course is designed to transform your child from a passive consumer of technology into an active, ethical AI creator.

Based on the personalized roadmap developed in the first session, the 5-week program delivers structured, project-based learning tailored to your child's cognitive strengths and interests, specifically addressing any learning barriers identified during the diagnostic phase.

What we achieve in 5 weeks:

Week 1-2: Foundations of Machine Learning & Critical Thinking: We move beyond definitions, using interactive projects to understand how AI learns (data, bias, pattern recognition). This builds critical thinking about the technology they use daily.

Week 3-4: Ethical Generative AI for Creativity: Students learn to master prompt engineering to create digital art, stories, or game concepts using generative AI tools. Safety and Ethics are paramount: we focus on responsible usage, digital citizenship, and copyright basics.

Week 5: The Final AI Creator Project: personalized mini-project (e.g., training a simple image classifier or writing a fully co-authored AI story) to demonstrate autonomy and mastery of the core concepts.

As your specialized 10+ year tech educator and coach, I ensure:

SEN Integration: Continuous adaptation of project requirements and delivery methods to ensure students with Special Educational Needs (SEN) maintain confidence and measurable progress.

Skill Transfer: We teach skills that translate directly to school projects, not just AI theory, but advanced digital literacy and structured problem-solving.

The software development course I propose to teach students covers the entire application creation process, from needs analysis to software deployment. Students will learn the fundamentals of programming (variables, conditions, loops, functions), the principles of object-oriented programming, and best practices for code structuring and documentation. They will be introduced to web and/or desktop application development, the use of databases to store and manipulate information, and the use of modern development tools (programming environments, version control, testing). Emphasis will be placed on completing concrete projects to develop both technical skills and the ability to solve real-world problems independently and methodically.

Fort de plus de treize années d’expérience dans le domaine de l’IT, j’ai développé une expertise approfondie aussi bien sur des technologies de pointe que sur des langages de programmation plus généralistes. Cette double compétence me permet d’offrir un accompagnement adapté à différents niveaux, du débutant complet au professionnel souhaitant se perfectionner.

Cours avancés – Spécialisation SAP :
En tant que consultant et développeur SAP expérimenté, je propose des formations de haut niveau couvrant notamment :
- ABAP (développement avancé, optimisation, bonnes pratiques)
- Architecture SAP

Ces cours s’adressent aux professionnels, étudiants ou entreprises souhaitant monter en compétence sur l’écosystème SAP, comprendre ses mécanismes internes ou améliorer la qualité de leurs développements.

Cours accessibles – Langages de programmation généraux :
En parallèle, j’enseigne également des bases solides en programmation pour ceux qui souhaitent découvrir ou renforcer leurs compétences dans des langages plus courants, tels que :
- Java
- JavaScript
- HTML / CSS
- Python
- C / C++

Je peux aussi accompagner des personnes en difficultés d'utilisation informatique.

Ces cours peuvent être orientés initiation, pratique guidée, exercices progressifs ou projets concrets, selon les besoins et le niveau de l’apprenant.

Mon approche pédagogique
- Explications claires et structurées
- Mise en pratique immédiate
- Adaptation au rythme et aux objectifs de chacun
- Transmission de bonnes pratiques issues du terrain
- Focus sur la compréhension réelle plutôt que la mémorisation
