Hello, I am an electrical engineer having an extensive experience as a professor in higher education in engineering science and electrical engineering, as well as great experience as an embedded systems engineer, in EE architecture, ADAS, Testing and validations in the automotive sector.

I offer support courses and training in engineering science subjects, particularly in Automation and Industrial Control, to graduate students. My methodology is based on the acquisition of knowledge and course concepts in a very simple manner and also on practical experience using the most widely used software on the market.

Automation is the discipline that, generally speaking, deals with the control of systems. It is therefore very important in the industrial field, to which it provides solutions, study methods, and systematic analysis approaches. It is a scientific discipline that studies dynamic systems, signals, and information for the purposes of control or decision-making.

This course consists of six chapters, divided as follows:

Chapter 1: Introduction to Automation & Controlled Systems
Chapter 2: Mathematical Modeling of Controlled Systems
Chapter 3: Time & Frequency Analysis of Controlled Systems
Chapter 4: Controlling Systems & Block Diagram Algebra
Chapter 5: Stability & Performance of Controlled Systems
Chapter 6: Correction and Regulation of Controlled Systems

Passionate & empathetic teacher. I have a Master's in Physics with honors from the University of Leicester (which was featured at the time as a top 5 Physics university in the UK by The Guardian) and a - french - European School diploma in which I achieved 90% in Physics and 85% in Maths.

Helping others understand difficult topics and skills is something that I am very passionate about as an empathetic person. I have 5 years of experience teaching Physics and Maths to kids from unprivileged backgrounds both in a homework schools as well as via private teaching. In private teaching, I have experience tutoring people with learning disabilities (ADHD, Dyslexia, Discalculia and more), younger kids of ages 7-12 and older students preparing for their final baccalaureate exams in advanced maths/physics curriculums.

In my classes, I aim to:

- help students achieve better grades in exams/tests in all branches of Physics & Maths
- clearly explain and break down topics
- give context and or example applications of topics (to improve understanding and memorization)
- help with ADHD & other learning disabilities
- give practical advice for university applications (eg. UCAS in the UK) and discuss the exciting Physics research/work and projects you can work on later in life.

Physics has a plethora of useful and fascinating applications, from the detection of Gravitational Waves and Gamma-Ray Bursts to the development of novel Medical Imaging techniques and Nano-technology (eg: smartphones). It is a subject that I am very passionate about and I hope to make use of my years of experience and extensive knowledge to help you understand and love the subject! My lessons will always be tailored to the individual needs of the student, so please do not hesitate to contact me if you have questions!

The TU Delft Aerospace Engineering Bachelor is one of the most prestigious bachelor programmes the Netherlands has to offer. As it is highly sought-after by students all around the globe, there is a highly competitive selection procedure which needs to be completed to get admitted to this popular degree. A major part of this admission procedure is the selection exam, consisting of three different tests: Mathematics, Physics and First-Year Material.

As a cum laude graduate Aerospace Engineer at TU Delft, who has also been tutoring since 2017, I have a lot of experience and knowledge of the program to help you out with the right preparation to get in. Over the last four years, I have helped tens of students secure a spot! Moreover, I offer a free personalised lesson plan for each student, which is fully based on the admission syllabus and past exams, to ensure an even higher chance of admission for each student.

With my calm and stepwise explanation, weaker topics will be addressed, and your solution procedures will become more effective and accurate. Each lesson will either be theory, exercise-based or an opportunity to talk about the admission, student life, the city of Delft, what to expect from the study and whether it is the right fit for you.

Beat the 15% TU Delft Acceptance Rate! Over the past 2 years, more than half of my students have successfully passed the selection process. To kick things off, I’m offering a 2-for-1 first class: we’ll build your personalized study strategy and complete your first full lesson in a 2 hour sessions for the price of 1!

TU Delft is Europe's most prestigious university for aerospace studies, preparing some of the best engineers. However the selection procedure is tough and demanding, and only those prepared have a chance to succeed.

As a TU Delft student, I know from first hand how stressfull this process is, and can therefore help you succeed in the preparation of these exams.

Moreover, I have an extensive knowledge on the subjects tested on these exams, having taken them myself, completed the courses at university with excellent grades and teaching over 15 students for the entrance exam. The reviews left by the students show how satisfied they are with the classes!

Throughout the class, I will use a presentation to explain the main concepts of each exam (Maths, Physics and Aerospace Engineering), focusing on those subjects the student is struggling with most. After this, I will help the student complete some practice excercises, and then assign extra practice to complete on their own time. These exercises will then be reviewed in the following class to ensure the topics have been understood. Near the exam, I will provide you with more than 1000 exam-type questions for you to get toned-up right before the real test!

I am looking forward to help you in your journey as an aerospace engineer!

📐 Learn Calculus Without the Confusion — Step by Step!

Does calculus sometimes feel like a collection of complicated formulas that are difficult to remember?

Maybe you've learned the rules for derivatives or integrals, but you're not really sure why they work or when to use them.

Don't worry — you're not alone! 😊

I'm Reza, a Computer Engineer, teacher, and technology enthusiast. I enjoy teaching mathematics and technical subjects by breaking difficult ideas into smaller, easier-to-understand pieces.

My goal isn't to make you memorize a lot of formulas. I want you to understand calculus and become confident solving problems on your own.

📚 What can we learn together?

Depending on your level, course, and goals, we can work on topics such as:

Functions and graphs
Limits and continuity
Derivatives and differentiation
Rules of differentiation
Applications of derivatives
Related rates
Optimization problems
Curve sketching
Introduction to integration
Definite and indefinite integrals
Fundamental Theorem of Calculus
Applications of integrals
Mathematical problem-solving
Exam and homework preparation

If you're studying calculus at school, university, or as part of an engineering or computer science program, we can focus specifically on the topics you need.

🎯 How do I teach?

I believe calculus becomes much easier when you understand the idea before learning the formula.

That's why I usually start with an intuitive explanation, then work through examples together, and finally give you problems to solve yourself.

We'll take things step by step.

If you make a mistake, that's completely fine. In fact, mistakes are often one of the best ways to learn mathematics. We'll find out where the mistake happened, why it happened, and how to avoid it next time.

And please ask questions! There are no "stupid" questions in my classes. If something doesn't make sense, I'll try to explain it in a different way until it becomes clear.

👨‍🎓 Who is this class for?

This class can be suitable for:

High school students
University students
Engineering and Computer Science students
Students learning calculus for the first time
Students who want to strengthen their mathematical foundations
Students preparing for calculus exams
Students who need help with calculus homework or exercises
Anyone who wants to understand calculus rather than simply memorize formulas

I will adapt the lessons to your current level, your goals, and your learning pace.

💡 My teaching philosophy

For me, learning mathematics isn't about being "good at math."

It's about finding the right explanation, practicing enough, and gradually building your confidence.

You don't have to understand everything immediately.

We'll take it one concept at a time.

Understand → Practice → Make mistakes → Learn → Improve.

That's my approach to teaching.

🚀 Ready to make calculus easier?

Whether you're struggling with limits, derivatives, integrals, or simply want a stronger understanding of calculus, I'd be happy to help.

Let's stop being afraid of calculus and start understanding it. 😊

Learn Easy. Learn Smart. Let's solve it together! 📐
