Personal Description:

Hello! I'm Ivan, a dedicated data analyst and statistician with a strong academic background from the University of São Paulo, Brazil (one of the top 100 in the QS ranking of best universities in the world). With over 9 years of experience in both public and private sectors, I specialize in data analysis, statistical modeling, and business intelligence using Python, R, SQL, Power BI, and QlikView. Tutoring is my side job, but it receives a significant amount of my effort and attention. Beyond my analytical skills, I am passionate about teaching math, physics, Portuguese, and computer skills (whether it's basic Windows, Microsoft Office or Python/R for data science).

Tutoring Experience:

Since childhood, I've been the go-to person whenever someone needed assistance with material, particularly in Math, Portuguese, and English as a foreign language. My formal teaching journey began as a teaching assistant at the University of São Paulo, where I supported students in math, statistics, and data analysis courses. I've also developed curriculum materials, graded exercises and exams, always providing constructive feedback and paying attention to detail.

Tutoring Approach:

My methodology includes:
- active learning (exercises and problem-solving tasks)
- breaking down complex concepts into smaller parts
- continuous feedback and assessment
- real-world examples
- visually appealing presentations or notes
- role reversal, where I ask the student to explain to me (or to an imaginary person) what they have learned and pose questions to them
- repetition (especially spaced repetition), presenting the same content in different contexts
- inquiry-based learning, fostering curiosity
- structured and organized lessons so that students know from the outset what to expect and where we are heading
- demonstrations by solving exercises and encouraging students to solve them independently over time
- out-of-class exercises
- mnemonic techniques
- supportive and inclusive environment
- valuing mistakes as learning opportunities
