This course is accessible for all skill levels, from those who want to learn programming to those who are already familiar with it.

Therefore, the purpose of the course will depend primarily on your knowledge and what you wish to learn.

Obviously, if you are a complete beginner, you will be given an algorithm course to familiarize yourself with programming methods.
These algorithm courses will be complemented by exercises in Pascal, Python or Java (or other programming language according to your preference) where other concepts will appear as we go along (procedures, object-oriented, ...).
SQL courses will also be offered for intermediate and/or advanced level students.

The idea of this course is to help you understand concepts either through theory, through kata, or both.

The most advanced courses will focus on frameworks such as Vaadin, JavaFX, ...

In short, feel free to contact me for further information and/or to provide me with the information that will allow me to offer you a tailor-made course that meets your needs.
I remain available for an initial contact to assess your level or knowledge if you need it.

Data skills can change your career, and you don't need to be a "math person" or have a technical background to learn them. If you can use a computer and you're curious, you can do this. In just 10 hours of one-to-one lessons, you'll go from "I don't know where to start" to analyzing real data on your own.

Maybe you're a student who needs to analyze data for a course or a thesis. Maybe you're looking for your first job in data, finance or business and want a skill that employers ask for. Maybe you already use Excel every day, but your reports take hours and you suspect there's a faster way. Or maybe you've never written a line of code and the idea feels intimidating. This class is built for all of you, and every lesson starts from where you are today.

I'm an engineer, and I work with data, statistics and programming (SQL, Python, R, Excel) every day. I don't teach theory for its own sake. I teach the way I use these tools in real work: you get a real question, a real dataset, and a clear method for turning one into the other.

In 10 hours, you will be able to:

Write SQL queries on your own. Select, filter, sort and group data, combine several tables with JOINs, and answer real questions such as "which product sold the most each month?"
Clean and analyze data in Excel. Use lookup formulas, conditional calculations and PivotTables, and build clear charts, instead of spending hours on manual work.
Build your first Power BI dashboard. Import data, clean it with Power Query, create interactive visuals, and share a report that looks professional.
Explain your results. Turn a business question into a query or a dashboard, check that your results make sense, and present them to someone who doesn't know the data.
Show a finished project. Leave with a portfolio-ready analysis you can use in an interview or in your thesis.

How the 10 hours are organized (we adapt this to your level and goal)

Hours 1-2: Foundations. We define your goal, check your level, and cover your first SQL queries (SELECT, WHERE, ORDER BY).
Hours 3-4: SQL in depth. Grouping and summarizing data, JOINs across tables, and cleaning messy data.
Hours 5-6: Excel for analysis. Advanced formulas, PivotTables, and charts.
Hours 7-8: Power BI. Importing and cleaning data, building visuals, and creating an interactive dashboard.
Hours 9-10: Your project. We put everything together on a realistic dataset (sales, finance, HR or your own data), and I give you feedback and a plan for what to practice next.

If you already know some Excel or SQL, we skip what you know and spend more time on what you need. If you want to go deeper later (for example advanced DAX, Python or statistics), we can continue from the same foundation.

How the lessons work

Every lesson is one-to-one and tailored to you. You practice on your own screen with my guidance, so you learn by doing rather than by watching. Between sessions I can give you short exercises if you want extra practice, and you can send me questions anytime. If you have your own files or work data (anonymized, of course), we can use them, which makes the learning much more relevant. Otherwise I provide practice datasets.

I explain in English or French (or Arabic if that's easier for you), and I'm patient. There are no silly questions. If something doesn't click, I'll explain it another way until it does.

Who this class is for

Students in business, economics, engineering, science or social sciences
Job seekers and career changers who want a first step into data analysis
Professionals who want to automate reports and work faster
Complete beginners. No previous experience with SQL or Power BI is needed.

I offer academic support in Python and SQL programming, aimed at secondary and higher-education students as well as individuals transitioning into data-related, IT roles or those who follow AI-focused courses.

I work in the field of AI and data science, combining both theoretical foundations and practical applications. Having learned Python and SQL almost exclusively on my own, I am well aware of the blockers that learners face, whether it be programming logic, debugging, code structure and so on.

Lessons are fully tailored to your needs:
• learning Python or SQL fundamentals
• assistance with assignments, projects, or coursework
• exam preparation
• improving best practices and problem-solving skills
• help throughout your training sessions.

The focus is on deep understanding, autonomy, and developing a structured analytical mindset, rather than mindless learning.

The time spent on lesson preparation and any necessary research is fully included in the proposed rate. I can travel to the student’s home for an additional fee.

Are you studying DAM, DAW, ASIR, Computer Engineering or other technological training and need help with SQL or databases?

The classes are online, one-on-one, and fully tailored to your syllabus, level, and goals. We can start from scratch, prepare you for a subject or exam, help you with practice problems, work on a project, or delve deeper into more advanced topics.

We can work on content such as:

* database design and modeling;
* entity-relationship diagrams;
* relational model;
* standardization;
* creation and modification of tables;
* SQL queries;
* JOIN and relationships between tables;
* subqueries;
* aggregation and grouping functions;
* views;
* procedures and functions;
* triggers;
* transactions;
* PL/SQL;
* query optimization and debugging;
* Connecting databases to applications.

We can work with **MySQL, MariaDB, PostgreSQL, Oracle** and other database management systems depending on the technology you use in your subject or project.

My goal is not for you to memorize queries. We will work to help you learn to analyze what information you need, which tables are involved, how to relate them, and how to build the solution step by step.

We can also work on your own exercises, practices, databases or projects, as well as prepare exams and assignments for vocational training or university.

In addition to the classes, you will have access to our educational platform with its own documentation, examples, exercises, practices and other resources to continue working between sessions.

I work as a data consultant and hold a master's degree in Data Science and Statistics from UCLouvain. I use SQL and databases in a professional context.

I offer SQL courses for students, beginners and people wishing to learn how to query and manipulate data in a structured way.

The lessons are tailored to your level and your goal. We can work on, among other things:

* understand how a relational database works;
* Write your first SQL queries;
* SELECT, WHERE, ORDER BY and DISTINCT;
* GROUP BY, HAVING and aggregation functions;
* understand and use the different types of JOIN;
* subqueries and CTE;
* SQL functions and window functions;
* Data manipulation and analysis using SQL;
* understanding and optimization of queries;
* solving exercises and preparing for exams;
* Debugging and correcting SQL queries.

I favor a practical approach: we start with exercises or concrete datasets and gradually build the queries. The goal is to understand the logic behind SQL rather than memorizing commands.

I can also assist you with an exercise, project or student work by explaining the process, the questions and the errors encountered, without doing the work for you.

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.

Are you studying DAM, DAW, ASIR, Computer Engineering or other technological training and need help with SQL or databases?

The classes are online, one-on-one, and fully tailored to your syllabus, level, and goals. We can start from scratch, prepare you for a subject or exam, help you with practice problems, work on a project, or delve deeper into more advanced topics.

We can work on content such as:

* database design and modeling;
* entity-relationship diagrams;
* relational model;
* standardization;
* creation and modification of tables;
* SQL queries;
* JOIN and relationships between tables;
* subqueries;
* aggregation and grouping functions;
* views;
* procedures and functions;
* triggers;
* transactions;
* PL/SQL;
* query optimization and debugging;
* Connecting databases to applications.

We can work with **MySQL, MariaDB, PostgreSQL, Oracle** and other database management systems depending on the technology you use in your subject or project.

My goal is not for you to memorize queries. We will work to help you learn to analyze what information you need, which tables are involved, how to relate them, and how to build the solution step by step.

We can also work on your own exercises, practices, databases or projects, as well as prepare exams and assignments for vocational training or university.

In addition to the classes, you will have access to our educational platform with its own documentation, examples, exercises, practices and other resources to continue working between sessions.

I work as a data consultant and hold a master's degree in Data Science and Statistics from UCLouvain. I use SQL and databases in a professional context.

I offer SQL courses for students, beginners and people wishing to learn how to query and manipulate data in a structured way.

The lessons are tailored to your level and your goal. We can work on, among other things:

* understand how a relational database works;
* Write your first SQL queries;
* SELECT, WHERE, ORDER BY and DISTINCT;
* GROUP BY, HAVING and aggregation functions;
* understand and use the different types of JOIN;
* subqueries and CTE;
* SQL functions and window functions;
* Data manipulation and analysis using SQL;
* understanding and optimization of queries;
* solving exercises and preparing for exams;
* Debugging and correcting SQL queries.

I favor a practical approach: we start with exercises or concrete datasets and gradually build the queries. The goal is to understand the logic behind SQL rather than memorizing commands.

I can also assist you with an exercise, project or student work by explaining the process, the questions and the errors encountered, without doing the work for you.

Data runs the world, and SQL is how you talk to it. Learn to query, design, and manage databases with confidence.

I've worked with SQL and databases for 3 years, building queries, analyzing data, and securing databases behind real applications for government, financial, and telecom organizations. I'll teach you the practical skills used on the job, not just textbook theory. No boring lectures, just live, hands-on practice.

You'll learn:

How databases work: tables, rows, keys, and relationships
Writing queries with SELECT, WHERE, ORDER BY, GROUP BY, and JOIN
Inserting, updating, and deleting data safely
Database design basics: normalization and schemas
Subqueries, aggregate functions, and useful real-world query patterns
Performance basics such as indexes, plus how to keep your data secure and avoid SQL injection

Perfect for: beginners, students, career changers, developers, analysts, and anyone preparing for a data or IT role.

You'll walk away with the ability to write your own queries, understand how data is stored, and a strong foundation for data analysis, development, or backend work.

No experience needed, just curiosity and a computer. Book your first session and let's get querying!

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.
