Online Maths Tutor Andrés

I'm a university-level math, computer science, and AI tutor based in Ecuador with 10+ years of teaching experience and 5+ years tutoring online. I've helped students master everything from first-year calculus to advanced topics like Theory of Computation, Discrete Mathematics, and the math behind Machine Learning.

🌍 Students from 13+ countries: United States, United Kingdom, Germany, Ukraine, United Arab Emirates, Spain, France, Italy, Australia, Argentina, Colombia, Peru, and Uruguay — including students from leading universities worldwide.

📘 University Courses I've Tutored:
ETH Zürich – Computer Science:
• Analysis I
• Linear Algebra
• Discrete Mathematics
• Algorithms and Probability (A&W – Algorithmen und Wahrscheinlichkeit)

King's College London – BSc Computer Science (Online):
• Foundations of Computing 1 (4CCS1FC1)
• Elementary Logic with Applications (4CCS1ELA)
• Data Structures (4CCS1DS1)
• Database Systems (4CCS1DBS)

General University Courses:
Calculus I–III, Multivariable Calculus, Linear Algebra, Probability & Statistics, Ordinary Differential Equations, Numerical Methods, Algorithms & Data Structures, Introduction to Data Science, Introduction to AI & Machine Learning

What students get when they work with me:
✅ Personalized lessons — fully customized to your syllabus, exam, and learning style
✅ Strategic study plans — built around your deadlines and long-term academic goals
✅ Interactive sessions — real-time problem-solving with advanced digital tools
✅ AI-friendly approach — I actively use AI tools (ChatGPT, Claude) to enhance learning, and I'll teach you how to use them correctly — as a learning aid, not a shortcut

✅ Bilingual support — fluent in English (B2) and Spanish (Native)

🤖 Artificial Intelligence & Machine Learning Foundations
I specialize in the mathematical and conceptual foundations of AI — the part where most students get stuck:
• Introduction to AI & Machine Learning (university-level)
• Math for ML — Linear Algebra, Probability, Statistics, and Calculus applied to ML
• Core ML concepts — supervised vs. unsupervised learning, model evaluation, gradient descent
Note: I focus on theory and the math behind AI/ML rather than deep learning framework implementation (PyTorch/TensorFlow).
