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.

In this training, we will try to describe what is object-oriented programming (often abbreviated as OOP) and model this approach with these different concepts. My goal is to advance the student to reach his goal without overloading it.

Do you want to learn how to program desktop applications in Java, C language, C ++, CSharp (C #), PSeint, Visual Basic .NET, Macros in Excel?

Do you want to learn how to program mobile applications in App Inventor 2?

My teaching methodology is Project Based Learning (PBL).

In this way, to build an application, I will teach you that the really important thing before sitting down to code (by attempt and error) in front of the computer, is the analysis and design of the algorithm (which constitutes 90% of the success of the program to be implemented. ), for this, with an example from the real world, the construction process will be explained: 1. Example with data from the real world, 2. Collection of information on requirements (input data, calculations, output data), 3. Hierarchy of operators (mathematical formulas versus computational formulas), 4. Desk test on a spreadsheet, 5. Constants, variables and data types to use, 6. Algorithm construction, 7. Flowchart, 8. Desk test on paper, 9. Implementation of the algorithm in the chosen programming language, if it is in console mode, it is implemented directly, if it is in form mode, the user interface is drawn on paper (UX) first.

Learn web development through practical, hands-on lessons designed to help you understand how modern websites are actually built.

Lessons can cover HTML, CSS, JavaScript, responsive web design, React, website creation, Git and GitHub, development tools, testing and deploying websites online.

Rather than focusing only on theory, we'll work through practical exercises and projects so you can apply what you're learning and gradually build your own websites.

Lessons can be adapted around your current experience and goals. Whether you're completely new to coding, already learning web development, working on your own project or looking to strengthen your existing skills, we can focus on the areas where you need the most support.

Topics can include:

• HTML and website structure
• CSS and responsive design
• JavaScript fundamentals
• React and component-based development
• Website creation and development
• Git and GitHub
• Development tools and debugging
• Testing websites
• Deploying projects online
• Building portfolio projects
• Understanding the web development process

The aim is not simply to give you answers, but to help you understand why things work, how to solve problems independently and how the different parts of web development fit together.

I am an experienced computer science teacher with many years of teaching experience and a university degree in Mathematics and Computer Science.

I offer individual online lessons in programming and computer science for school students, as well as support for university students in selected subjects. Lessons can cover Python, MATLAB, SQL and databases, algorithms and programming fundamentals, computer systems, and web development with HTML, CSS and JavaScript.

My lessons are adapted to each student's previous knowledge, current curriculum and individual goals. I explain concepts step by step and focus on understanding the logic behind programming rather than simply memorizing code.

We can work on current school or university topics, programming exercises and assignments, fill gaps in knowledge, prepare for tests and exams, or develop practical programming skills.

Lessons are taught online in Serbian, Bosnian or Croatian, which can be particularly helpful for students from families from the former Yugoslavia who live and study in Germany, Austria, Switzerland or other countries.

Do you want to learn SQL, better understand databases, or get support with your exercises and projects?
As a computer science teacher, I have taught databases at the university level. I offer progressive support tailored to each learner's level.
We can work on data modeling, relational databases, tables and relationships, primary and foreign keys, as well as SQL queries: SELECT, WHERE, JOIN, GROUP BY, subqueries and other concepts depending on your level.
The sessions emphasize practical application: explanation of concepts, concrete examples, exercises, and then problem-solving.
The course can also serve as support to understand a course, prepare for an assessment or progress on a personal or academic project.

Learn to program with a practical, patient approach. I'm a working software engineer with a bachelor's degree in informatics, and I teach students who want to truly understand code, not just copy it.

Languages and technologies I can teach:
- Java, C++ and C#: fundamentals, object-oriented programming, data structures and algorithms
- JavaScript and TypeScript: from the basics to modern syntax, typing and working with APIs
- HTML & CSS: building and styling real web pages
- SQL and relational databases: queries, joins and database design

What we can do together:
- Learn programming from scratch, step by step, with no prior knowledge needed
- Work through university or school assignments and prepare for exams
- Build a small project from idea to working result
- Understand concepts you are stuck on, such as recursion, pointers, OOP or async code
- Prepare for a technical interview or your first job in IT
- Learn good practices used in real-world software development: clean code, debugging, version control (Git)

Lessons are 45 minutes long and fully adapted to you. We write code together, I explain the reasoning behind each step, and you gradually take over. Beginners are very welcome, and so are students who already know the basics and want to move forward faster.

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