About Ammar
I am a PhD Engineer, university professor, researcher, and multidisciplinary technical educator with more than 25 years of experience in engineering, data analysis, statistics, research methodology, programming, databases, and professional software applications.
I have taught and supported university students, graduate researchers, engineers, analysts, managers, professionals, and career-transition learners. My students range from complete beginners to advanced learners working on assignments, dissertations, research studies, dashboards, database applications, technical projects, and workplace analyses.
My teaching approach is based on a simple principle: complex subjects become much easier when the theory, method, software, and real-world application are connected clearly.
I do not teach software as a collection of isolated commands. I explain what the analytical problem means, why a particular method or tool should be used, how the calculations and data structures work, how to identify errors, and how to verify that the final result is technically and logically correct.
My expertise includes:
• Microsoft Excel, Power Query, Power Pivot, dashboards, macros, and VBA
• Python, pandas, NumPy, Matplotlib, Seaborn, Jupyter Notebook, Anaconda, and Visual Studio Code
• SQL, MySQL, Microsoft Access, Oracle, SQL Server, and PostgreSQL
• Relational database design, normalization, entity–relationship modelling, ETL, and data warehousing
• Microsoft Power BI, DAX foundations, Tableau, data visualization, and analytical storytelling
• Statistics, research methodology, data preparation, validation, reproducibility, and technical reporting
Lessons are personalized to your level and objectives. I can help you learn systematically from the beginning, understand difficult theory, solve technical problems, complete an assignment, analyze research data, improve a professional report, prepare for an examination or interview, or develop an end-to-end analytical project.
My goal is to help you become more accurate, confident, and independent. You should leave the lesson understanding what was done, why it was done, how to verify it, and how to apply the same reasoning to future problems.

B- PERSONALIZED TUTORING: LEARN TO THINK
-------------------------------------------------------
Data analysis is not simply about using Excel, writing SQL queries, or building dashboards. It is a complete reasoning process:
Define the question → understand the data → prepare it → analyze it → verify the results → visualize the evidence → communicate the conclusion.
My lessons help you understand this full workflow so that you can work accurately, independently, and confidently with academic, research, business, engineering, or organizational data.
Each lesson is personalized to your current level, software environment, dataset, assignment, examination, workplace task, or professional objective. We begin by identifying what you already know, the expected result, and the main conceptual or technical difficulties. We then establish a clear and practical learning plan.
The first free lesson combines a discussion of your background, objectives and tutoring needs, an initial assessment of your current knowledge, personalized planning and scheduling, and a short trial lesson so that we can determine the most effective way to work together.
Lessons may follow a complete real-world workflow:
Question definition → data import → cleaning → database design → SQL extraction → Excel or Python analysis → BI modelling → dashboard development → interpretation → report or presentation.
You may work with your own assignment, thesis data, research project, professional dataset, business report, or portfolio project, provided that confidential information is handled appropriately.
A typical lesson may include conceptual explanation, live software demonstration, guided practice, troubleshooting, validation, and a concise summary of the next steps.
My objective is not merely to fix one formula, complete one query, or build one chart. It is to help you understand the analytical process, select the correct tool, identify why errors occur, verify your results, and communicate reliable conclusions.
