Looking to master programming and become a skilled developer? In this course, you'll learn the basics of Python and other programming languages, as well as how to use them to build machine learning models. We also offer specialized assistance for students in programming and database management using SQL.

Python is a powerful general-purpose language used in web development, data science, software prototyping, and more. Its simple and easy-to-use syntax makes it an excellent choice for beginners learning to program.

Additionally, upon request, we offer courses in other programming languages such as C, JAVA, R, and MATLAB.

Classes can be conducted remotely or in person, and we tailor our instruction to meet individual or group needs.

If you have any questions, feel free to contact us.

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).

My courses are designed for beginners as well as those with some prior knowledge who want to improve their programming skills or create their first web projects. I always begin by assessing your level and objectives (e.g., understanding the basics, completing an assignment, building a complete website, etc.). Then, I tailor the course entirely to your pace so you can learn without stress. I offer a comprehensive learning experience that combines theory (to understand the concepts) and practice (to apply them immediately). This allows you to progress faster and truly master what you learn. Teaching Methods: Simple explanations with concrete examples for the theory; Guided practical exercises to reinforce understanding; Mini-projects to directly apply each new concept; Correction and improvement of your own projects if you have any. Typical Session Structure: Quick review of previous concepts; New concept explained progressively; Practical exercises or mini-project to apply; Questions/answers + personalized advice; Work plan to continue between sessions (optional). What sets me apart: Simple teaching methods adapted to beginners; Balanced mix of theory and practice; Personalized support according to your objectives; Patience and step-by-step explanations; Possibility of creating concrete projects from the very first lessons.
