Private 1-on-1 Online Coding Classes for Kids in the US
Guide your child from passive screen time into active software engineering and autonomous robotics. From Scratch game mechanics to Python, AI, and AP Computer Science prep — taught live 1-on-1 by Silicon Valley-caliber mentors mapped to CSTA Standards & AP Computer Science Frameworks.
Dedicated Silicon Valley mentor assigned to your child's pace.
What American Students Build
From intuitive drag-and-drop block logic to university-level object-oriented Python, machine learning, and hardware robotics.
What Your Child Actually Builds & Deploys
No passive lectures. Every month concludes with a deployed playable game, live web app, or hardware prototype verified in our curriculum.
Interactive Treehouse Platformer
Playable 2D platformer with custom character sprites, jump physics, coin/fruit collection variables, and sound effects.
Pygame 2D Arcade: Dark Maze Quest
2D arcade adventure coded in Python: keyboard velocity controls, sprite hitboxes, and dynamic player flashlight surface masking.
HTML5 & CSS Grid
Responsive Pet Portfolio Web App
Multi-page mobile-responsive website coded from scratch with CSS Grid layouts, interactive pet profiles, and live web hosting.
Arduino C++ Firmware
Autonomous Sonar & Line Rover
Physical robotic rover with HC-SR04 ultrasonic distance sensors, infrared path-tracking modules, and C++ autonomous motor loops.
We don't teach kids about technology.
We teach them to think in it.
Private 1-on-1 mentorship for American students — converting passive screen addiction into autonomous engineering, mapped to CSTA standards, and scheduled in your local US time zone.
Passive Consumption
The Screen Time Trap
Hours lost to infinite algorithmic video feeds, repetitive games, and non-productive screen fatigue with zero computational thinking.
Active Engineering
Computational Intuition
Transforming fascination with tech into real Python code, custom physics engines, algorithmic logic, and responsive web apps.
Tangible Mastery
College-Ready Portfolios
Deploying working projects to GitHub, wiring physical microcontrollers, and building pride in software they created from scratch.
1-on-1 Dedicated Mentorship
Every session is 100% private. An expert mentor focuses entirely on your child's questions, curiosity, and pacing — zero waiting, zero peer distraction, and real-time screen coaching.
Your US Time Zone (ET · CT · MT · PT)
Whether you're in New York (ET), Chicago (CT), Denver (MT), or Los Angeles (PT), we offer weekday after-school and weekend times that fit your family.
CSTA & AP Computer Science Prep
Direct alignment with College Board AP Computer Science Principles and AP CS A (Java) standards to give your teen a tangible high school edge.
Creator Portfolio, Not Worksheets
Students build playable games, publish live websites, and engineer physical Arduino rovers they can proudly showcase in college applications.
Paper first.
Code second.
We teach children to think before they type. Every project starts with planning — what will it do? What does the user see? Only then do we open the laptop.

Every STEMulus mentor is an industry professional — developers, AI researchers, and robotics engineers who genuinely celebrate when your child has an "Aha!" breakthrough.
In their own words.
Authentic feedback from US parents whose kids attend weekly 1-on-1 STEMulus sessions.
"Daniel built his first playable game in 3 sessions. His confidence with math, logic, and computers has soared. The 1-on-1 focus made all the difference."
"What impressed me most was that nobody tried to sell us. The discovery session was genuine, informative, and our mentor gave clear milestones for AP CS."
Transparent USD Pricing · Private 1-on-1
All classes are private 1-on-1, 60 minutes long. Billed monthly. Pause or cancel anytime with zero lock-in contract.
Coding Foundations & Python

Your Child’s Safety Is Our #1 Priority
Every mentor undergoes identity verification and thorough multi-state criminal background screening. Sessions are conducted in secure virtual classrooms with open-door parent access and zero private unmonitored messaging.
Frequently Asked Questions for US Parents
What hardware or software does my child need?
A laptop or desktop computer (Mac, Windows, or Chromebook) with a reliable internet connection, working webcam, and microphone. All coding software used (Scratch, Python, VS Code, Replit) is free.
How does the free 45-minute discovery session work?
It is a real, live 1-on-1 session with a mentor. Your child will build their first hands-on mini-project during the call. The mentor assesses their learning style, and we share a personalized curriculum recommendation. No credit card is required.
Can STEMulus help my teen prepare for AP Computer Science?
Yes. We offer targeted 1-on-1 mentorship for AP Computer Science Principles and AP Computer Science A (Java), covering data structures, object-oriented design, pseudo-code analysis, and College Board exam practice.
