Hello! 👋
I'm Gym Coding, a coding education creator 😊

I teach simply enough for non-developers to follow, and with enough depth to satisfy professionals.
I am currently a full-stack developer of 13 years and the CEO of an IT startup.

I have personally designed and built everything from front-end, back-end, and AWS infrastructure, including service development for major corporations like KT and Kia, the Cafe24 e-commerce platform, smart city IoT data platforms,
and even the services I currently operate myself.

Currently, while focusing on education, I maintain my industry expertise by directly developing my own services.

Translating that real-world experience into a language that even beginners can understand—that is what I do through my lectures.

        Thank you, Yeji! I'm so glad you found the difficult concepts easy to understand. I believe anyone can learn complex programming syntax if it's explained step by step, which is how I prepared the lectures, so I'm happy to hear that it was helpful. Please feel free to ask any questions you may have as you continue learning! 💪
