arrow icon
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. You are also welcome to bring a dataset or project you would like to understand, provided it does not contain confidential information.

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)
• Additional professional training and certifications in Microsoft Excel, Power BI and Data Analytics
Experience / Qualifications
I work as a Senior Consultant and Professional Trainer at Dupleix Institute, where I design and deliver physical, virtual and hybrid training programmes for students, professionals and corporate organisations.

I have delivered courses in Power BI, Advanced Excel, SQL and SSIS, Python, R, artificial intelligence, financial modelling, project-finance modelling, fraud analytics, internal-audit data analysis, IFRS 9 Expected Credit Loss modelling, credit scoring, stress testing and ICAAP.

My professional experience also includes developing analytical dashboards, AI-assisted business tools, financial models, IFRS 9 systems, credit-scoring solutions and risk-management platforms for financial institutions. This experience enables me to connect academic concepts with practical workplace applications.

I prepare structured lesson materials, datasets, exercises and case studies, assess learners’ understanding and provide individual guidance. My lessons focus on practical skills, accurate reasoning and the learner’s ability to apply knowledge independently.

Stuck in Excel? Want to finally understand how those formulas really work? Do you need to create a pie chart of your expense report for work or school, but feel completely lost? Don’t worry! I’m here to help... at your pace, with no jargon or complicated explanations.

Whether you:
- are starting completely from scratch,
- already have some basic knowledge,
- or want to solve a specific problem,
we’ll tailor the session to your needs. No one-size-fits-all course, just practical help that actually works for you.

👨‍🏫 About me
I’ve been using Excel since I was a teenager — for personal use (like budgeting tools or calorie trackers) and professionally as part of my work and studies in data analysis. Thanks to my experience and structured approach, I explain Excel in a clear and understandable way. I know how frustrating it can be when something technical doesn’t work... and how satisfying it feels when it finally clicks.

🎯 Topics we can cover
- Smart formulas (IF, VLOOKUP, INDEX, MATCH, etc.)
- Creating charts, pivot tables, and dashboards
- Using Excel for budgeting, planning, or managing projects
- Data analysis and basic programming in Excel
- Preparing for Excel tests or improving job-related Excel skills

💻 Practical info
- Having your own laptop/PC is helpful, but not required
- Online or in-person sessions possible
- Have specific questions or files you’d like to work on? Let me know! I also have my own practice materials.

Feel free to send me a message with your question or goal. I’ll gladly look at how I can help you out!

Who should attend ?
This course is specifically designed for seniors, young retirees, or anyone wishing to update their computer skills at their own pace. No prior technical knowledge is required. Patience, clarity, and a supportive approach are at the heart of this training.

Why take this course?
Information technology should no longer be a barrier, but a tool to simplify your daily life and keep you connected with loved ones. This program has two objectives: to make you completely proficient with standard software (Word, Excel) and to introduce you, in a simple and engaging way, to the new Artificial Intelligence (AI) technologies that everyone is talking about.

Educational goals :
At the end of this learning cycle, you will be able to:

Drafting and formatting administrative or personal documents.

Managing a family budget or creating simple organizational lists.

Understand what Artificial Intelligence is (like ChatGPT or Gemini) and use it as a personal assistant on a daily basis.

Detailed program (Syllabus)
The program is adaptable to your initial level. Each session includes simplified theory and plenty of practice.

Module 1: The basics of office software (Microsoft Word)

Exploring the interface: the keyboard, the mouse, and the word processing screen.

Enter, correct and format text (bold, italics, colours, alignment).

Write an official letter or a letter to loved ones.

Save, find your document on the computer, and print it.

Module 2: Daily Organization (Microsoft Excel)

Understanding the principle of tables and cells.

Create simple lists (address book, shopping list).

Create a tracking table for the monthly budget (expenses, income).

Use basic formulas (automatic sum) to have the computer calculate for you.

Module 3: The Arrival of Artificial Intelligence (Chatbots)

What is Artificial Intelligence (AI)? A simple explanation and demystification.

Discover virtual assistants (ChatGPT or Gemini): how to access them for free and securely.

The art of the "Prompt" (the query): how to ask the right questions to the machine to get the best answers.

Practical workshops with AI:

Ask him to draft a complex email.

Looking for recipe ideas using leftovers from the fridge.

Have him summarize a long newspaper article.

Organize a travel itinerary from A to Z.

Module 4: Safety and Best Practices

Recognizing reliable information in the face of AI "hallucinations" (errors).

The golden rules for protecting your personal data on the internet and in Office documents.

My Pedagogical Methodology
The approach is entirely personalized. I adapt to your learning pace. Each new concept is immediately followed by a practical, concrete exercise directly related to your everyday needs (writing to an administration, planning your vacation, etc.). Simplified course materials can be provided at the end of each session to help you review on your own.

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.
