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).

Unlock the world of programming with a clear and practical course designed for complete beginners.
In this class, you'll learn the foundations of JavaScript, one of the most widely used languages in modern web development.

Through simple explanations and real examples, you’ll understand how to write your first programs, solve problems using logic, and build small interactive projects. My teaching approach focuses on practice, clarity, and step-by-step guidance—perfect for students who want to start their coding journey with confidence.

By the end of the course, you’ll be able to:

Understand variables, conditions, loops, and functions

Build basic JavaScript programs that run in the browser

Work with events and manipulate the DOM to create interactive pages

Apply programming logic to solve real-world problems

Develop a solid foundation to continue into front-end or full-stack development

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. My courses are suitable for students from middle school to university level, as well as adults wishing to learn web development or change fields.

Are you ready to build and publish your own Data Science Portfolio on a free platform?
In this course, I will guide you step-by-step through creating a clean, professional, and fully shareable portfolio website.

We will integrate your CV, your Data Science projects, and (if you have one) your GitHub profile into a ready-to-publish website.
By the end of the lesson, you will have a complete and personalized portfolio that you can confidently share with employers, recruiters, and collaborators.

You will also learn how to update and customize your portfolio so it truly reflects your skills and style.

Your portfolio will be completely free to maintain - no monthly, yearly, or one-time subscription fees. It will be fully open-source, and anyone can view it through a simple link without downloading anything or signing up for any platform.

This is a basic course to strengthen the students ability to understand the basics of programming and Web Development. At the end of the course, the students will develop an interest in programming with a good theoretical and practical knowledge of how things work.

In my lessons, I start by understanding exactly what the student needs, taking time to empathize and identify his/her challenges. I then check the students' prior knowledge and readiness for the topic he/she wants to learn. From there, I explain the content step by step, making sure the student can follow each stage clearly. I use visual and interactive tools, such as a tablet, to make learning more engaging and easier to understand. By the end of the lesson, I always ensure the student’s needs have been met and that they feel confident moving forward.

Arduino is a powerful and beginner-friendly platform for learning electronics and programming. If you’re interested in building real-world projects like smart devices, sensors, and automation systems, Arduino is the perfect place to start.
In this class, you’ll learn how to program Arduino using C/C++ basics, understand how electronic components work, and connect sensors, LEDs, motors, and displays. The course is designed as a practical, hands-on guide, focusing on building and testing real projects rather than just theory.
By the end of the class, you’ll be confident in writing Arduino code, reading sensor data, controlling hardware, and creating your own embedded system projects—from simple circuits to more advanced applications.

My classes are geared towards teenagers, young adults, and adults who want to learn programming from scratch. I explain the fundamentals with practical examples and simple projects, adapting the pace to each student. The goal is for you to acquire a solid and understandable foundation to confidently advance in the world of software.

I offer personalized academic support for primary and secondary school students to help them improve their understanding, confidence, and performance in school. My lessons focus on explaining concepts in a simple and clear way, assisting with homework, test preparation, and strengthening weak areas.
I adapt my teaching style according to each student’s learning needs and pace. Whether your child needs regular academic support, exam preparation, or help with specific subjects, I provide structured and supportive lessons in a friendly learning environment.
My goal is to help students build strong foundations, develop good study habits, and achieve better academic results with confidence.
