I am a Ph.D. student at the University of Luxembourg. For the past 4 years, I taught the University: statistics and probability theory to first-year students, and economics to 3th-year students.

I really enjoy teaching. I am looking forward to helping students when they need reinforcement on different subjects, or anyone interested in learning the following topics:

For maths: System of equations, derivatives, integrals, type of equations, etc.

For statistics: Probability theory, descriptive statistics, regression analysis, multivariate analysis, hypothesis testing, and methods for causal inference.

For young professionals: I have extensive experience in data analysis, data management, and statistical modeling. My class mixes both theoretical and practical parts using financial data as examples.

If you are interested, just write me a message telling me what topics are you interested in learning.

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 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.
