Hello, welcome to our neighborhood coding studio !

Our Neighborhood Coding Studio is an educational group created by developers who majored in computer engineering at major universities in North America, such as Carnegie Mellon, Washington, Toronto, and Waterloo , and gained practical experience at global IT companies such as Google, Microsoft, and Meta .

It started as a study group for computer science majors from the US and Canada who wanted to study and grow together . Even though we were from different universities and in different time zones, the time we spent solving problems together and learning from each other was very special, and naturally, I had this thought.

“What if we could teach others the same way we studied?”

That question was the starting point for our neighborhood coding studio .

Currently, about 40 current developers and computer engineering college students are in charge of their respective areas of expertise, and they directly design and teach a curriculum that covers everything from introductory to practical. Beyond simply imparting knowledge, we provide an environment where you can learn from the perspective of a real developer and grow together .

“Real developers should learn from real developers.”

We systematically cover the entire process of web development from start to finish, but we do not stop at theory, but develop your skills through practice and practical feedback .
Our philosophy is to think about and guide the growth of each and every student.

Our philosophy is clear:
"True learning comes from practice, and growth is accomplished when we do it together."
