I offer mathematics lessons suitable for all levels and ages, up to baccalaureate level. I offer different types of courses:
- Regular lessons to maintain a constant level of competence.
- "Intense" courses over a period of a few days or weeks, during which we will work for several hours in a row in order to prepare for an exam or a specific project.
- Preparatory courses to help students make the transition to higher education.

My main objective is to help and accompany the student by offering theoretical courses, as well as practical exercises to apply the theory that we have studied together. I place great importance on concrete examples, because theoretical mathematics can seem abstract to many people.

I can also provide support to students who carry out studies or data analyzes as part of their written work.

As an engineer, I would like to help other students navigate the sometimes complex world of mathematics and physics. During my studies, I tutored for 6 years in secondary schools in the region of The Hague, Delft, Rotterdam and Antwerp. I try to go through the course material interactively with the student and link theoretical concepts as much as possible to examples from our daily lives in order to prepare and motivate the student.

So if you would like tutoring on one or more subjects in mathematics or physics, you can contact me.

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
