Python is one of the best, if not the best, language to start learning programming. It is also one of the most widely used languages today, especially in cutting-edge areas such as machine learning.

This popularity means that Python is constantly evolving. It offers a wide range of tools and libraries, which are free and very varied.

As an aeronautical engineer, I like to share my knowledge and derive satisfaction from it by teaching and motivating others.

I'm used to working with people of different ages. I believe in the importance of segmenting learning, visualizing progress, setting concrete goals and practicing regularly.

Beyond these general principles, there is no magic rule or method. Some approaches work with some students but not with others. Adaptation to individual needs is therefore the main objective of private lessons. So I will do my best to find what motivates and helps my student.

I teach Python specifically for finance and data applications - the kind used in economics, business analytics, and quantitative programs. This isn't a general "learn to code" course; it's built around real financial data, benchmarking, and the workflows you'll actually use in coursework or early career work.

Topics include:
Python fundamentals through a finance lens (data structures, functions, control flow).
Working with financial data and datasets.
Performance benchmarking and writing efficient code.
Applying concepts from Hilpisch's Python for Finance.

I teach machine learning, AI and Python online to university students, postgraduates, career changers and serious beginners across the UK and Europe. Lessons are in English.

I hold an MSc in Electronics and Electrical Engineering with Distinction and I teach as a Visiting Lecturer on a Master's level module covering data analytics, machine learning and generative AI at a UK university. I also have two accepted international conference papers on deep learning for image classification. I set and mark postgraduate assignments myself, so I know where marks are won and lost on this kind of work.

Who this is for

Undergraduates and postgraduates on AI, ML, data science or computer science modules at any European university. Final year, Master's and thesis students working on a machine learning project. IB and A Level students moving into computing or engineering. Professionals retraining for data roles. Complete beginners who want to learn Python properly rather than copying it from videos.

I work with students on UK, IB and continental European programmes. I have tutored engineering students in Germany and international school students across several countries, so an unfamiliar syllabus or a module taught in a different structure is not a problem. Send me the material and I will work from it.

What we cover

Python for data science with NumPy, Pandas, Matplotlib and scikit-learn. Deep learning using TensorFlow and Keras. Core theory including regression, classification, clustering, decision trees, random forests, neural networks and CNNs, together with the linear algebra, calculus and statistics underneath them. Computer vision and image classification, which is my published research area. Model evaluation, overfitting and hyperparameter tuning. Writing machine learning work up to academic standard, covering methodology, results and critical evaluation.

How lessons work

Send me your module handbook, assignment brief, thesis spec or the code that will not run, and I plan the session around it before we meet. Nothing generic.

In the lesson I explain the concept with a worked example, then you take the keyboard while I watch and correct, because you learn far more doing it than watching me do it. You finish with annotated notes and a clear next step, and you can message me between sessions with questions.

Practical details

Online over Google Meet or Zoom with screen sharing and a shared whiteboard. Sessions run 60 or 90 minutes. I am based in the UK and teach across GMT and Central European time, with evening and weekend slots that suit students anywhere in Europe.

Tell me your course, your deadline and exactly where you are stuck, and I will come back with a plan for the first session.

I offer courses in mathematics, Python, and SQL, as well as an introduction to data and artificial intelligence. The content is tailored to your objective: consolidating the fundamentals, gaining a better understanding of a course, preparing for an assessment, or completing a first practical project.

My MIASHS degree from Toulouse Jean-Jaurès University and my experience in data and AI within the Airbus environment allow me to connect theoretical concepts to practical applications. I work primarily with Python, SQL, and data processing and analysis tools.

My approach: identify your difficulties, explain each concept with a concrete example, and then have you practice gradually. We work on your reasoning and independence, with tailored exercises and explained solutions.

In mathematics: tutoring for middle and high school students, tailored to the curriculum and individual needs. In Python and SQL: introduction, foundational knowledge, data manipulation, and small projects for beginners or those wishing to improve their skills. For AI: understanding the uses, limitations, and principles of current tools.

The courses are conducted in French, remotely. We define the objectives together before the first session.

This class is for people starting from zero or close to it: school students taking informatics, first-year university students struggling with their programming course, or adults who want to learn to code and don't know where to begin.

We work through the fundamentals properly rather than rushing: variables, conditions, loops, functions, lists and dictionaries, reading and writing files, and how to break a problem into steps before you write a single line. We go at your pace, and you write the code yourself while I guide you, because watching someone else type teaches you nothing.

If you're stuck on a specific university assignment or school project, bring it and we'll work through it together. I won't do it for you, but I'll make sure you understand it.

I teach in English and Polish.
