Practical Data Analytics with Excel, Power BI, SQL,R and Python

From 20 € /h

Data analytics is an essential skill for students, professionals and organisations that want to make informed decisions using data. This practical class will help you develop the skills required to clean, analyse, visualise and interpret data using widely used analytical tools.

Depending on your learning objectives, lessons may cover Microsoft Excel, Power Query, Power BI, SQL or Python. You can learn how to clean and transform datasets, write formulas and queries, develop data models, calculate meaningful performance indicators and design interactive dashboards.

Each lesson is customised according to your current level and goals. I use clear explanations, guided exercises, realistic datasets and practical projects to help you understand both the technical steps and the business meaning behind the results.

This class is suitable for beginners, university students, job seekers and working professionals. By the end of the programme, you should be able to analyse data more confidently, create professional reports and apply your skills to academic or workplace projects.

About Me

I am a patient, practical and supportive tutor who enjoys helping learners understand difficult concepts and apply them confidently. My teaching style combines clear explanations, step-by-step demonstrations, guided exercises and real-world examples.

Before beginning a lesson, I take time to understand the student’s current knowledge, challenges and learning objectives. I then adapt the lesson to suit their pace and preferred way of learning. I encourage students to ask questions, practise during lessons and explain their reasoning rather than simply memorising procedures.

I particularly enjoy teaching teenagers, university students, job seekers and working professionals who want to improve their academic performance or develop practical career skills. Depending on the subject, students may work with datasets, dashboards, financial models, case studies, coding exercises and realistic business scenarios.

My goal is to create a comfortable learning environment and help every student become an independent, confident problem-solver.

Education

• Master of Science in Financial Engineering — WorldQuant University, currently in progress
• Bachelor’s Degree in Forensic Accounting — University of Zimbabwe
• Microsoft Certified: Power BI Data Analyst Associate (PL-300)

I specialized in tutoring Microeconomics and Macroeconomics for students in IB and AP programs. I have students from various high schools in Turkey and besides that I also teach AP Microeconomics&Macroeconomics at a high school in Istanbul. I have a PhD in economics from Georgetown University and I have worked as an Associate Professor of Economics and Finance in various universities in Turkey.
With 10 years of experience as a Professor of Economics I do not let the students memorize the concepts. Instead I ensure that they get the logic and they are able to apply theoretical concepts to real life issues.

This class is designed for students who are new to economics, as well as learners from other academic or professional backgrounds who want to develop a solid understanding of economic thinking and fundamental economic theories.

With more than 4 years of teaching experience, I have learned that the most effective way to teach economics is not simply to explain theories, but to encourage students to think like economists. Instead of memorizing definitions and models, we will explore why economic ideas make sense and how they can be used to understand the world around us.

Real-life examples and practical applications are at the heart of this class. We will connect economic theories to everyday decisions, businesses, markets, government policies, prices, and other situations that students encounter in real life.

The goal is to give you more than an introduction to economics: by the end of the class, you should have developed a way of thinking that allows you to look at real-world situations through an economic lens.

I am a professional professor of economics in Poland since 2005. I teach Economics HL and SL in the IB program in one of the best schools in Warsaw since 2013. I can explain your doubts and help you with the Internal Assessments. I don't speak Spanish, I only speak English.
I graduated from Szkoła Główna Handlowa w Warszawie (Warsaw School of Economics) and have completed all the necessary trainings for the previous and current syllabus.
All the classes are based on what you need to know for your final IB exam, but I explain it in an unconventional way so that you understand better. I adjust the methodology to each my student. I have a lot of experience teaching groups and individuals. All my students always get good grades on Internal Assessments and final exams.

Kids don't need lectures about "good money habits." They need to feel what money does.
While adults debate finances at home, kids are already using money, without actually understanding how.

In this course, we learn by playing. And by thinking.
We'll explore together:
✓ Simulate a real shop: handle actual money, practice spending and saving, discover what it feels like
✓ Create a personal budget: not boring spreadsheets, but visuals, games, and real challenges
✓ Ask the real questions: Need vs. want. Why save? How do people earn? What's debt?
✓ Discover how systems work: Banks, loans, digital money, and financial security
✓ Think like an entrepreneur: What services can I offer? How do I create value? How do I turn an idea into money?

Why this is different:
Most kids think "money is complicated." This class shows them that money is a tool, not a mystery, not something to fear.
And, more importantly: that they can control it.

What they take home:
A personal budgeting system they actually understand. Answers to questions they've been asking. And the mindset: money is a means, not an end.

Format: Online or Barcelona | 60-min sessions | Small group or one-on-one

For curious kids who ask questions about money.

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 accounting courses for secondary school students, particularly in vocational training, as well as for first-year bachelor's students at university or college.

The objective is to help the pupil or student understand accounting logic, master important entries and know how to solve exercises in a structured way, whether for a quiz, an exam, a qualification or a refresher course.

I primarily support pupils and students who wish to review the basics, better understand accounting mechanisms and practice on typical exercises.

Subjects covered according to your program:

• Basics of accounting:
debit/credit, asset and liability accounts, expenses and revenues, chart of accounts, account logic, supporting documents and reading statements.

• Journal and accounting entries:
recording of current operations, purchases, sales, payments, receipts, VAT, customer and supplier accounts, entries with or without discount.

• VAT and commercial transactions:
VAT to be recovered, VAT to be paid, purchase invoices, sales invoices, credit notes, trade discounts, rebates, incidental expenses and calculations related to commercial transactions.

• Depreciation:
straight-line depreciation, declining balance depreciation, depreciation schedules, depreciation charges, net book value and year-end entries.

• Provisions and adjustments:
provisions, deferred charges, accrued income, charges to be allocated, deferred income, inventory entries and year-end adjustments.

• Balance sheet and income statement:
construction of the balance sheet, assets/liabilities, equity, debts, expenses, revenues, profit or loss for the year, link between the income statement and the balance sheet.

• Basic financial analysis:
working capital, working capital requirement (WCR), net cash, simple ratios, reading and interpretation of financial statements.

• Cash flow:
operating cash flow, investment cash flow, financing cash flow, distinction between accounting profit and cash flow.

• Exam/qualification preparation:
Typical exercises, past quizzes, exams, case studies, problem-solving methods, guided correction and identification of common errors.

I can also help with economics depending on the level and program, particularly in microeconomics and macroeconomics: supply and demand, elasticities, costs, competition, market, growth, inflation, economic policy and basic models.

Method of working :

1. We identify the chapters that pose a problem;
2. I will re-explain the accounting logic with simple examples;
3. We redo the exercises step by step;
4. I show how to recognize the type of writing or calculation required;
5. We construct a clear method so that the student can do it on their own.

I do not limit myself to giving a correction: I explain the reasoning behind each writing and each calculation so that the subject becomes more logical and less mechanical.

I have been giving private lessons for over 7 years in mathematics, statistics, economics, and accounting. I also have a degree from Solvay/ULB and professional experience in finance and business controlling at Deloitte, which allows me to explain accounting with an approach that is academic, university-level, and practical.

Courses available in French or English, online or in person in Brussels or the surrounding area.

As a high school Economics and Management teacher and former lawyer, I currently teach law and economics in the final year of STMG (Science and Technology of Management and Business).
I offer private lessons to high school and university students who wish to better understand these subjects, consolidate their knowledge, acquire an effective work method or prepare for an exam.
In law, we work on understanding legal concepts and vocabulary, classifying facts, formulating legal issues, identifying applicable rules, and constructing rigorous legal reasoning. Depending on the level, support may also include practical cases and methodological exercises for higher education students.
In economics, I prioritize understanding mechanisms rather than mechanical learning: mastering concepts, analyzing documents and data, mobilizing knowledge and constructing a reasoned response.
The sessions are tailored to each student's needs: reviewing a poorly understood chapter, reinforcing fundamental concepts, methodology, targeted exercises, and preparing for an assignment or exam. I can also provide summary materials when necessary.
Particular attention is paid to the quality of reasoning, the precision of vocabulary, and written expression.
My goal: to enable the student to understand, reason methodically and gradually become autonomous.

Additional materials + practice qs | Lesson plans | Recording + session notes available

Our time together starts by mapping out a clear goal - better grades, understanding the content at a deeper level, or even the small things like figuring the "diagram bits" out. Whatever the goal, we'll lay it out and build a plan around it.

Each lesson is tailored to this plan, with one common theme - simplify
When they ask to "Assess whether a government tax on producer-side pollutants is the best way to reduce market failure."

We'll know exactly:
- What market failure actually means, and how governments fix it
- How to develop points for an "assess" question
- Which diagram we can use to flesh out our answer (and how to explain it properly)
- and many more pro tips :)
