Learn to code with method and logic
Whether it's to succeed in the NSI (Digital Sciences and Technology) specialization in high school, design personal projects, or prepare for higher scientific studies, mastering code relies on solid algorithmic thinking. I help students understand the structure of programming languages and the logic of data.

Subject areas and languages taught:

Algorithms & Logic: Designing data structures and solving problems.

Programming Languages: Python, C/C++, C# and Java.

Data Management: Analysis and SQL queries / databases.

Basic Web Development: HTML & CSS for creating structured pages.

The goal is to take the student from simply writing code to true autonomy in development.

Python is the programming language these days. It is simple, nice and almost all modern applications use it. With Python, we can now create artificial intelligence models that reduce human effort and give us more accurate and reliable results. The Java and C languages are not lacking in importance, they also make it possible to create applications optimized in terms of RAM.

The composition of the course depends on the level of the student and his own objectives. The first session is a one-hour evaluation session which allows the diagnosis of the level and the needs of the student. From this diagnosis we establish together a program that we will follow during our course.

Generally the course allows the student to assimilate:
* Predefined Data Types & Variables;
* Conditional Structures & Loops;
* Functions ;
* Object-oriented programming (OOP);
* Digital engineering;
* An introduction to databases (Examples and uses)
* Relational Algebra
* LDD, LCD, LMD, LCT
* SQL queries (SELECT, UPDATE, ...)
* Creation of a database and automation of queries using the Python language
* Handling files (TXT, Excel, CSV, JSON, Word);
* Data science;
* Introduction and some applications of Artificial Intelligence.

I am waiting for you to start this adventure.

Learn practical software development skills through structured lessons tailored to your current experience, learning goals and interests.

These lessons are designed for beginners and developing learners who want to understand how software is planned, developed, tested and improved.

Topics can include programming fundamentals, application development, problem-solving, program logic, working with data, databases, APIs, version control with Git and GitHub, debugging, testing and understanding the software development lifecycle.

Depending on your goals, lessons can also introduce technologies used in modern software development such as JavaScript, TypeScript, React, Node.js and working with front-end and back-end applications.

The focus is on learning through practice rather than simply studying theory. We can work through coding exercises, small applications, software challenges and portfolio projects to help you understand how the different parts of software development work together.

Lessons can also support students who want help understanding an existing project or want to strengthen particular areas of their development knowledge.

No previous programming experience is required for beginner lessons.

Learn SQL by writing real queries, not by memorizing theory.

I'm a working software engineer with a bachelor's degree in informatics, and I use SQL and relational databases in practice. I teach it step by step, with hands-on examples, so you understand what each query is doing and why.

I work with all major database systems: MySQL, PostgreSQL, Microsoft SQL Server, Oracle Database and SQLite. Whichever one your course, job or project uses, we can learn on that one and I'll point out the differences in syntax between them.

What we can cover:
- SELECT basics: filtering, sorting, grouping and aggregate functions
- JOINs (inner, left, right) and subqueries, explained visually
- Creating and modifying tables, keys, relationships and constraints
- Database design and normalization
- Indexes and writing queries that run faster
- Help with university or school assignments, exam preparation and practice tasks
- Preparing for a job interview or a first project that needs SQL

Lessons are 45 minutes long and adapted to your level. Complete beginners are very welcome, and if you already know the basics, we can go straight to the topics you find difficult. We work on example databases, or on your own assignment if you have one.

Lessons are available online, or in person in Zagreb. They can be held in English or Croatian.

I'm a Computer Science master's student at TU Delft and I build with these tools every day. I've written and open-sourced a pipeline for working with AI coding agents, and a lot of that work was about finding where the output quietly goes wrong. That's the part most tutorials skip.

This class is for people who use AI at work, or are being told to, and want to actually get something out of it. No programming background needed.

We cover: writing a prompt that gets a usable answer the first time, giving the model your own documents and data to work from, using it for drafting, summarising, analysis and research, building a repeatable workflow instead of starting from scratch every time, and the important part, how to spot when it's confidently wrong.

We work on your actual tasks, not toy examples. Bring something real from your job and we'll build a workflow around it.

I teach in English and Polish.

✈️ Former ENAC Airline Pilot Cadet
🧑‍💼 State Engineer in Electronics, Electrical & Telecommunications
🧑‍🏫+10 Years of Distance Learning +7000 Hours of Courses Taught
⭐ Co-Founder of www.Mathssansfrontieres.com
📚 Specializing in preparation for Baccalaureate/Rheto/Brevet/CE1D exams.
🌍 Proficiency in the following programs: 🇫🇷, 🇧🇪, 🇨🇭, 🇨🇦, 🇲🇦, 🇦🇪
📅 Available from 8 AM to 11 PM, with the possibility of adapting to multiple time zones.
♾️ If I am more than 5 minutes late, the session is free.

At 33, I proudly wear the hats of engineer and former ENAC cadet pilot. But my favorite role is that of a passionate teacher!

My educational journey, marked by steady progress from elementary to high school, taught me a valuable lesson: simplicity is the key to understanding. Inspired by Einstein's words, I strive to explain complex concepts with such clarity that even a child could grasp them. This pedagogical approach is at the heart of my teaching method.

The goal is to demystify and break down the lessons so that my students can, in turn, teach them with ease. My passion for mathematics, strengthened by over 10,000 hours of experience, naturally led me to teaching this discipline.

My personal quest is fulfillment through my daily activities. My career began in engineering before I ventured into piloting with the best flight school in Europe, ENAC. However, it was in distance learning that I discovered a true passion. This mobility allows me to teach from all corners of the world (Indonesia, France, Morocco, etc.) and to undertake assignments in Japan, India, Vietnam, Sri Lanka, and elsewhere, all while staying connected with my students.

The gratitude of parents, witnessing their children's progress, is invaluable. I greatly appreciate the friendly relationship I cultivate with my students.

Our courses transcend traditional subjects, embracing sports, cinema, manga, video games... I strive to create a relaxed atmosphere where learning becomes a pleasure, thus making the concept of time secondary.
