Ex-Amazon SDE & Northeastern MS | Algorithms, Data Structures, Web Dev, Interview Prep

Hi, I'm Chaoyi, a CS tutor with a Master's from Northeastern University (GPA 3.86) and industry experience as a Software Engineer Intern at Amazon. I've spent 2+ years teaching as a Graduate TA and Peer Mentor at Khoury College of Computer Sciences, helping students master Data Structures, Algorithms, and programming concepts. My background is unique: I started as an interaction designer in China before transitioning into software engineering. I know firsthand what it feels like to struggle with CS and how to break it down clearly and patiently. I specialize in: - Data Structures & Algorithms (CS courses and technical interviews) - Web Development: React, TypeScript, JavaScript, Node.js - Debugging & Code Review — fix bugs and understand why they happen - Homework & Project help — step-by-step guidance, not just answers - Exam prep & interview readiness — from Amazon experience and 350+ LeetCode problems My teaching is practical and concept-first. Once you understand *why* something works, you stop memorizing and start thinking like an engineer. I use real-world examples and live coding to make hard topics approachable. Whether you're in AP CS, struggling with algorithms, or prepping for tech interviews, let's work together and get you there!
