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."

From beginners just starting out in development, job seekers looking to develop practical skills, to young people exploring their career paths.
Our neighborhood coding studio aims to be everyone's starting point and a strong companion as we walk together.

Now, don't worry alone.
Our neighborhood coding studio will grow with you.

Welcome to Neighborhood Coding Studio !

Neighborhood Coding Studio was founded by a team of developers who studied computer science at top North American universities such as Carnegie Mellon, the University of Washington, the University of Toronto, and the University of Waterloo , and went on to gain hands-on experience at global tech companies like Google, Microsoft, and Meta .

It all began as a study group formed by computer science students across the US and Canada , created to grow together by sharing knowledge, solving problems, and learning from one another.
Although we were attending different schools in different time zones, the experience was so meaningful that it led us to one simple thought:

“What if we shared this way of learning with others?”

That thought became the foundation of Neighborhood Coding Studio .

Today, we are a team of around 30 active developers and computer science students , each taking responsibility for their area of expertise—designing and delivering a curriculum that spans from foundational knowledge to real-world development.
We're not just here to teach—we're here to help you see through the lens of real developers and grow together .

“To become a real developer, you must learn from real developers.”

Our courses take you through the entire web development journey—from start to finish—focused on hands-on practice, real-world projects, and practical feedback .
We care deeply about each learner's growth and are committed to supporting your path every step of the way.

Our philosophy is simple but powerful:
“True learning comes from doing, and true growth happens together.”
