Hi there! I’m Alex. I hold Bachelor’s degrees (with Honors) in Applied Mathematics and Statistics from UC Berkeley, and a Master’s in Statistical Science from UC Santa Cruz. I’ve worked with students at many levels — from high school through graduate coursework.

Before grad school, I spent a year as a high school math substitute teacher. Since completing my Master’s, I’ve tutored a wide range of subjects including Calculus, Discrete Math, Algorithms, Probability Theory, and Bioinformatics.

In my sessions, I plan ahead with clear examples and targeted practice problems. I’ve found that working through problems together in real time is the best way to identify challenges, strengthen intuition, and build lasting confidence.

If this approach sounds right for you, feel free to reach out with questions or schedule a lesson. I look forward to helping you reach your goals!

Approved Subjects

Chess

Chess

I am an experienced chess player with a rating around 1900 and a deep understanding of both strategy and tactics. I have taught students of different ages and skill levels, helping them improve their openings, middlegame planning, and endgame technique. My approach emphasizes critical thinking, pattern recognition, and building confidence at the board. Whether the goal is to compete in tournaments or simply enjoy the game more, I tailor lessons to each student’s needs.
Common Core

Common Core

I have worked as a substitute teacher across multiple grade levels, where I delivered lessons aligned with Common Core standards in math, English, and science. My classroom experience required adaptability, clear communication, and strong classroom management to ensure students stayed engaged and on track. I am skilled at breaking down challenging concepts into understandable lessons while supporting diverse learning styles. This hands-on teaching experience has given me a strong foundation in guiding students through Common Core material effectively.
Computer Science

Computer Science

I have extensive experience in computer science, with a strong foundation in algorithms, data structures, and programming languages such as Python, Java, and C++. My background includes advanced coursework in algorithm design, graph theory, and parallel computing, as well as hands-on experience solving complex problems through competitive programming. I also bring practical expertise in data science and statistical modeling, making connections between theory and application. I enjoy tailoring lessons to each student’s needs, helping them build confidence while mastering challenging concepts.
Data Science

Data Science

I hold a Master’s degree in Statistical Science with extensive experience in data science, machine learning, and applied statistics. My background includes hands-on work with Python, SQL, and advanced algorithms, as well as research in graph theory and large-scale data analysis. I have also guided students and peers through topics ranging from probability and regression to deep learning and parallel computing. My goal is to make complex data concepts intuitive, while helping students gain the confidence to apply them in academic, professional, or research settings.
Data Structures

Data Structures

I have over two years of professional experience as a bioinformatics software engineer, where I applied data structures and algorithms daily to analyze large-scale biological datasets. I’ve also tutored students in Discrete Math, Algorithms, and Computer Science fundamentals, helping them strengthen their problem-solving intuition. My approach emphasizes breaking down complex structures into intuitive concepts and guiding students through hands-on practice.
Discrete Math

Discrete Math

I served as a teaching assistant for Discrete Math during my undergraduate studies at UC Berkeley, where I also completed advanced coursework in theoretical computer science and combinatorics. My experience includes leading discussion sections, grading, and holding office hours to help students master proofs, logic, set theory, and graph theory. Since then, I’ve worked with students one-on-one to build problem-solving confidence and strengthen mathematical reasoning. I emphasize clear explanations, step-by-step proofs, and plenty of practice problems to help students succeed.
Econometrics

Econometrics

I have a Master’s degree in Statistical Science with a strong foundation in econometrics, applied statistics, and data modeling. My expertise includes regression analysis, causal inference, and time series forecasting, along with hands-on experience applying these methods to real-world economic and financial data. I am skilled in using tools such as R, Stata, Python, and SQL for empirical analysis. I enjoy breaking down complex concepts into approachable lessons, helping students gain both the theoretical understanding and practical skills needed for success in econometrics.
Finite Math

Finite Math

I hold a BA from Berkeley in Applied Mathematics and have extensive experience tutoring finite math topics, including probability, logic, set theory, linear programming, and matrices. I focus on making abstract concepts clear through step-by-step explanations and practical examples. Many of my students come to me feeling unsure about math, and I enjoy helping them gain confidence and problem-solving skills they can use both in their coursework and beyond. My teaching style is patient and tailored to each student’s needs, ensuring they not only succeed in class but also understand how finite math connects to real-world applications.
Geometry

Logic

Logic

I have a BA in applied Mathematics and extensive experience tutoring courses in logic, discrete math, and proof writing. My expertise includes propositional and predicate logic, set theory, Boolean algebra, and formal proof techniques. I enjoy helping students strengthen their reasoning skills, whether they are preparing for advanced mathematics, computer science, or philosophy. My approach emphasizes clarity, step-by-step explanations, and building the confidence to tackle abstract logical arguments independently.
Machine Learning/ AI

Machine Learning/ AI

I hold a Master’s degree in Statistical Science with strong expertise in machine learning, artificial intelligence, and data science. My background includes building models for classification, regression, clustering, and deep learning using Python, TensorFlow, PyTorch, and scikit-learn. I also emphasize the mathematical foundations of ML, including linear algebra, probability, optimization, and algorithms, to help students deeply understand the 'why' behind the methods. I enjoy guiding learners through projects and problem sets that connect theory to real-world applications, from predictive modeling to natural language processing.
Probability

Probability

I have an MS in Statistics from UC Santa Cruz and a BA in Statistics (with honors) from UC Berkeley.
Real Analysis

Real Analysis

I have a BA from UC Berkeley in Applied Mathematics with extensive experience studying and teaching proof-based courses such as Real Analysis, Advanced Calculus, and Measure Theory. My background includes guiding students through rigorous topics like sequences, series, continuity, differentiability, and integration, as well as the foundations of metric and normed spaces. I place special emphasis on helping students strengthen their proof-writing skills and develop the intuition behind formal definitions. My goal is to make challenging material more approachable, while preparing students for success in advanced mathematics.
