Acerca de mí

The demand for Software Engineers has been rising extremely hight for the last 5 years and it presents great opportunities for people eager to learn and to develop themselves.

I believe it's very important how the tutor is teaching and presenting the materials to the students and the communication and common effort is the goal for successful results.

I am currently a Lead Software Engineer, working for a bank in Amsterdam. My technical expertise is mainly in Java, Javascript, Bash scripting and Software as a concept and way of thinking.

I have experience both as a professor and a lead engineer in many teams, as I like to help and explain to people any topics regarding software engineering, principals and how to be successful in the IT world.

If you need my help and want to share my experience with you do not hesitate to contact me!

As a current Master's student in Aerospace Engineering at TU Delft, I have successfully navigated the entire Bachelor's curriculum and the competitive selection procedure, so I am fully equipped to guide you through the study plan and specific admission requirements. I offer personalized tutoring sessions designed to ensure comprehensive preparation for the entrance exams. These classes include a detailed review of key concepts in Mathematics and Physics, intensive practice with relevant exercises, and specific strategies to tackle the test effectively. I also place a dedicated focus on mastering the First Year Material (FYM) section (often the most challenging and unfamiliar part for applicants) to help you build the confidence and skills necessary to succeed. Furthermore, I am happy to discuss the degree program itself and explore the opportunities available in Delft to help you prepare for your future student life.

80% of my students got accepted in the 2025 exam, I am sure I can help you out in the 2026 exam!

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. I have previous experience as a tutor back in high school, helping students improve their grades from Cs to As.

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 10 students for the entrance exam.

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.

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

Electronic engineering student. I'm looking to tutor secondary school (ESO) and high school (Bachillerato) students, as these are the subjects I'm most proficient in. My preferred subjects are mathematics, physics, technical drawing, and technology. I aim to teach through understanding, ensuring students know what they're doing and don't learn blindly. I start with theory and then apply it to fully grasp the concepts.

After an initial assessment, this course is designed to transform your child from a passive consumer of technology into an active, ethical AI creator.

Based on the personalized roadmap developed in the first session, the 5-week program delivers structured, project-based learning tailored to your child's cognitive strengths and interests, specifically addressing any learning barriers identified during the diagnostic phase.

What we achieve in 5 weeks:

Week 1-2: Foundations of Machine Learning & Critical Thinking: We move beyond definitions, using interactive projects to understand how AI learns (data, bias, pattern recognition). This builds critical thinking about the technology they use daily.

Week 3-4: Ethical Generative AI for Creativity: Students learn to master prompt engineering to create digital art, stories, or game concepts using generative AI tools. Safety and Ethics are paramount: we focus on responsible usage, digital citizenship, and copyright basics.

Week 5: The Final AI Creator Project: personalized mini-project (e.g., training a simple image classifier or writing a fully co-authored AI story) to demonstrate autonomy and mastery of the core concepts.

As your specialized 10+ year tech educator and coach, I ensure:

SEN Integration: Continuous adaptation of project requirements and delivery methods to ensure students with Special Educational Needs (SEN) maintain confidence and measurable progress.

Skill Transfer: We teach skills that translate directly to school projects, not just AI theory, but advanced digital literacy and structured problem-solving.
