About David

Bio

I’m a retired data scientist/algorithmic trader turned full-time educator with a deep love for mathematics and physics.
I hold Master’s degrees in Engineering and Mathematics from Columbia University, (where I graduated with a GPA above 4.0), as well as an MBA from the London School of Economics. Having competed in national Math and Physics Olympiads and later taught at the graduate level, I know what it takes to succeed.

I’m a retired data scientist/algorithmic trader turned full-time educator with a deep love for mathematics and physics.
I hold Master’s degrees in Engineering and Mathematics from Columbia University, (where I graduated with a GPA above 4.0), as well as an MBA from the London School of Economics. Having competed in national Math and Physics Olympiads and later taught at the graduate level, I know what it takes to succeed.
I specialize in AP Mathematics, AP Physics, and SAT preparation, helping students strengthen their conceptual understanding, problem-solving skills, and exam technique. My goal isn’t just higher grades or test scores (though we’ll get those!) — it’s helping students truly understand what they’re learning and build the confidence to tackle any challenge independently.

My teaching journey began as a graduate student at Columbia, tutoring high schoolers who were struggling with math and science. Since then, I’ve served as a teaching assistant and Dean’s Tutor for advanced university courses, supporting students in mastering everything from Calculus and Linear Algebra to Engineering Physics.

In recent years, I’ve helped students significantly raise their SAT scores — often by 100–200 points — through clear explanations, practical test strategies, and personalized feedback. Whether it’s working through tricky AP Calculus concepts or optimizing your SAT problem-solving speed, I bring patience, structure, and genuine care to every lesson.

I genuinely love mathematics and physics. That love is what drives my teaching, it’s not just about getting the right answers, but about building deep understanding and intellectual curiosity. My ultimate goal as a tutor is to guide my students to a point where they no longer need a tutor.

ACT Math

ACT Math

I specialize in SAT/ACT Math tutoring, combining deep subject knowledge with proven test strategies. I tutor ACT Math in-person through Columbia’s Tutoring Agency, helping inner-city students improve their scores and confidence. I’ve helped students reach their target scores and often surpass them through clear explanations and structured practice. My sessions focus on building problem-solving skills, pacing, and accuracy under timed conditions. Over the years, I’ve created my own comprehensive library of ACT-specific materials, organized by mathematical themes, subtopics, and difficulty levels. I teach students how to spot patterns, interpret tricky phrasing, and avoid common ACT traps. My custom drills include the most frequent question types and word-play variations seen on real tests. We also focus on pacing and building accuracy under timed conditions, so students perform their best on test day. Every session includes a balance of guided problem-solving, review, and independent practice to reinforce key techniques. Beyond content, I help students develop the confidence and composure needed for high-stakes testing. My ultimate goal is not just a score increase, but to equip each student with problem-solving skills that last well beyond the SAT/ACT.
Algebra 1

Algebra 1

In Algebra 1, I focus on three pillars: Concept clarity: making sure you truly understand the “why” behind each topic, not just the steps. Structured problem solving: breaking questions into clear, repeatable methods you can apply under test conditions. Confidence building: using targeted practice and review to help you feel steady and prepared before quizzes and exams. Over the years, I’ve created my own structured materials that group problems by topic and difficulty, so practice is always focused and effective. I also teach strategies for recognizing patterns, reducing errors, and tackling word problems with clarity and confidence. Algebra 1 is a foundational subject in Mathematics and first real challenge for many so I’m committed to helping you not only improve your grades but also build real confidence in the subject. More than just preparing for exams, my goal is to help you truly understand and even enjoy mathematics so future topics like calculus come naturally.

Calculus

Calculus

Calculus is where mathematics truly comes alive. It’s the bridge between abstract ideas and the real world. I’ve taught students at every level, from AP Calculus AB/BC to advanced multivariable and graduate-level courses. With two Master’s degrees in Mathematics and one in Engineering from Columbia University, I bring both academic depth and practical insight from my years working in quantitative finance and data science. My approach focuses on building strong conceptual understanding before moving to problem-solving mastery. I’ve helped AP students move from struggling to confidently scoring 5s, and guided university students through the toughest topics - from limits and derivatives to differential equations and vector calculus. Lessons are personalized to the student’s pace, goals, and preferred learning style. Whether your aim is exam success or a deeper appreciation of the subject, I’ll help make Calculus clear, intuitive, and rewarding.

Linear Algebra

Linear Algebra

I hold a Master’s in Applied Mathematics from Columbia University, where I also served as a teaching assistant and Dean’s Tutor for advanced math courses, including Linear Algebra. My professional background includes work in data science and algorithmic trading, both deeply grounded in Linear Algebra concepts like vector spaces, eigenvalues, and matrix transformations. I focus on building true conceptual understanding rather than rote computation. My students learn not just how to solve problems, but why the methods work and skills that translate directly to higher-level math and real-world applications.
Physics

Physics

Having studied physics to the postgraduate level and tutored AP students for years, I know how to explain even the toughest topics in clear, relatable ways. I use structured study plans, targeted practice, and custom review materials I’ve developed over time. Each lesson is tailored to student's needs, whether they’re aiming to boost a grade, solidify fundamentals, or achieve a top AP score. I take pride in helping students not only excel on exams but also grow to appreciate the beauty of physics. My lessons focus on building intuition, confidence, and problem-solving skills, so you can tackle both conceptual and calculation-based questions with ease.

Friendly and Easy Going.

David was a great guy and I always felt comfortable asking him to explain stuff I wasn't able to follow. He would also go into depth on stuff I was confused about and would always make sure I came out knowing what I was having trouble with or that I was comfortable with the topic.
