Trusted teacher: Code alone is no longer enough; learn to design effective solutions. Why are some programs faster than others? Why can choosing a list rather than an array make all the difference? This course is not just a programming lesson: it's an immersion in the pure logic of computer science. Whether you are a student in the middle of revision, a passionate self-taught person or a professional preparing for a technical interview (FAANG, Big Tech), I will give you the keys to solve any complex problem with elegance and efficiency. ⏱️ Choose your format "Flash" format (60 min): Ideal for an intensive introduction. We focus on vital concepts and fundamental structures with exercises for immediate application. "Expert" format (90 min): The complete session. We delve into complexity (Big O), solve high-level algorithmic problems, and explore advanced structures (Trees, Graphs). 🎯 What you will master The art of optimization: Understanding temporal and spatial complexity (Big O notation) to write professional code. The engineer's toolbox: Easily manipulate Tables, Lists, Stacks, Queues, Dictionaries and Trees. The logic of resolution: Implement the most efficient sorting and searching algorithms. Critical thinking: Knowing how to choose exactly the right data structure for each situation. 📑 Your progress plan The Essentials (10 min): Why algorithms are the beating heart of modern computing.

Computer science · Microsoft excel
Trusted teacher: Microsoft Office is now a virtually indispensable software suite for almost everyone, whether during our school years, through PowerPoint presentations, document creation with MS Word, calculations and graph creation in MS Excel, or during our professional lives. In the latter case, we need to get even more out of it in a minimum amount of time. Some may have noticed that it's possible to automate a series of actions by recording "macros" to save time. But have you ever considered that behind these macros lies computer code generated for you in "Visual Basic for Applications" (VBA)? Understanding this type of code and how it manipulates the "object model" associated with the application being used (for example, the worksheets, rows and columns, cells, and the values they contain, in the case of Microsoft Excel) allows you to go further in terms of automation and flexibility. The course is adaptable to the student and their level. Depending on demand and the number of sessions, it can cover the fundamentals of programming (variables, types, declarations, manipulations, local and global variables, etc.), illustrated using VBA, as well as best programming practices (error handling, using comments, standardizing variable names, code modularity), culminating in the creation of a project enabling interoperability between different Microsoft Office tools (for example, associating notes taken with OneNote with dates in a perpetual calendar created in Excel). It may even cover concepts such as object-oriented programming (polymorphism, encapsulation) and the differences between compiled and interpreted languages. The sky's the limit :))

rating green star
Haralambie has provided incredible support throughout our sessions in a variety of challenging areas of mathematics. The breadth of Haralambie's expertise is evident in the many ways he can demonstrate the idea. I have benefitted from Haralambie's clarity in showing the relevance of specific theorems and how they connect with upcoming material. I have learned a lot from our sessions and he marries the conceptual gaps that come up by explaining the ideas and properties very well. Haralambie provides guidance, patience, and context to the topics covered in subjects that are otherwise disorienting. We work together to hammer out a conceptual stump. My learning experience with Haralambie is fun and engaging, and his input and guidance has been incredibly helpful in elucidating areas that I have missed which improves my approach to future problems.

I need to re-study 4 years of high school maths in only 5 months. Mahmood agreed to help me with this difficult task and thanks to his professional way of teaching I believe I can make this happen. He explains topics in detail and yet quickly enough to spare time for other topics. If you are unsure he points you to the right direction. Most important thing for me was that he made me realize that I first need to master concept #1 in order to be able to later master concept #5 and so on. You can see that he has a lot of teaching experience, he tries to understand the way YOU think and based on that he serves you clear explanation for topics you struggle to understand. I definitely recommend him as your next teacher!

rating green star
I've been studying with Mohamed for several months now, and I can confidently say he is one of the smartest and most effective teachers I've ever worked with. He not only has a deep understanding of Python and Data Science, but he truly knows how to teach. Mohamed has a rare combination of strong technical expertise and outstanding teaching skills. He can explain complex topics in a simple and clear way, and he always chooses examples and exercises that really help you grasp the material. What I value most is his focus on practical application: we don’t get stuck in theory — we move straight to solving tasks that are relevant to real-world work. This makes each lesson extremely useful and efficient 👌🏼
