# Tutoring Session with Carlos Reyes

> One focused hour on whatever you’re working on: C++, Python, data structures, algorithms, AP Computer Science, coursework, or your own project. We learn by building — bring your code, and we work through it together. I’ll show you what’s happening under the hood and why it matters, not just which buttons to press. Teens, college students, and career changers welcome. Patient teaching, your pace, no dumb questions. Did you find me through a tutoring platform such as Crimson Education or Wyzant? I only take students booked independently. If you found me through a tutoring marketplace, please book through those websites instead.
