Am a PhD researcher in power systems engineering with a strong foundation in mathematics, probability, statistics, and data analysis, and several years of experience applying these tools to real-world problems. I specialize in making complex concepts simple, intuitive, and actionable, whether I’m teaching a student or helping a client extract insight from data.

📐 Online Math Tutoring
I provide one-on-one online tutoring for students at high school, undergraduate, and graduate levels. My teaching approach focuses on building intuition first, then connecting theory to problem-solving.

Subjects I tutor include:
• Calculus (I, II, III)
• Linear Algebra
• Probability & Statistics
• Optimization & Numerical Methods
• Differential Equations
• Engineering Mathematics

I adapt my explanations to the student’s background and learning style, and I emphasize why things work—not just how to solve problems. Many of my students come from engineering, data science, and economics backgrounds.

📊 Data Analysis & Data Science
I also work as a data analyst and data scientist, ML, helping clients turn raw data into clear insights and decisions.

What I can help you with:
• Data cleaning, preprocessing, and exploratory data analysis (EDA)
• Statistical modeling and regression analysis
• Probability-based and Bayesian modeling
• Machine learning
• Visualization and reporting (clear, publication-quality figures)
• Python-based analysis

My strength lies in rigorous analysis combined with clear communication. I don’t just deliver results—I explain what they mean and how they can be used.

How I Work
• Clear problem understanding before coding or teaching
• Well-documented, reproducible work
• Honest timelines and transparent communication
• Focus on long-term understanding, not shortcuts
