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

From 18 £ /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.

Extra information

Please bring a laptop with a reliable internet connection. Depending on the selected subject, you may need Microsoft Excel, Power BI Desktop, a SQL environment, Python or Jupyter Notebook installed. I can assist you with the required software setup during the first lesson.

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.

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.

Microsoft Office skills are expected in almost every professional environment — yet most people have never been properly taught how to use these tools efficiently.
This course covers Word, Excel, and PowerPoint at whatever level you need, from basic document formatting to advanced Excel functions and automation.
Excel (most popular):

Formulas and functions (VLOOKUP, INDEX/MATCH, IF, SUMIFS, and more)
PivotTables and data analysis
Charts and professional dashboards
Macros and VBA automation — eliminate repetitive tasks entirely

Word: Professional document formatting, styles, tables, mail merge
PowerPoint: Clean, professional presentation design and structure
This is a hands-on course — we work directly on your files and your real-world tasks, not generic exercises. You'll leave each session knowing exactly how to apply what you learned to your actual work.
Ideal for students, job seekers, administrative professionals, and anyone who wants to stop wasting time on manual work.

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.

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.
