The Best Vibe Coding Course

Why learn 22-year startup developerand
8.5B KRW agency CEOfrom a
vibe coding?

Problems when learning from non-experts

  • They only teach AI tool installation and usage, security vulnerabilities and operational know-howare never covered

  • They can't solve the technical problems students face

  • They only share prompts, but don't teach how to communicate with AI and solve problems

What makes heyjames different

  • With 22 years of diverse tech stack experience, we chose the most secure and AI-friendly technologies

  • We support students through technical problem solving, code reviews, and launch consulting/sprints

  • Practical guidance for non-developers to progress step by step - including debugging and prompting

  • After vibe coding, continue with full-stack development courses to safely launch complex platforms

Agile Business Methodology

New IT products shouldn't be perfectly planned from the start. Build and respond to user feedback as you go.

Courses that produce real results

Unlike courses where you can't build anything after. Systematically learn how to communicate with AI and solve problems.

Built in just one week by students who couldn't write a single line of code

바이브코딩 강의

바이브코딩을 처음 접하는 저에게는 최고의 강의였습니다. 여러 코딩툴(Cursor, Windsurf, Claude Code)을 사용하면서 실습할 수 있어서 정말 좋았습니다. 제임스님의 목소리와 딕션도 훌륭해서 강의에 더 집중할 수 있었습니다.

바이브코딩 강의

바이브코딩으로 하나의 서비스를 만들고 배포하는 과정을 모두 지켜볼 수 있는 좋은 기회가 됐습니다. 단순히 비개발자도 뭐든 만들 수 있어요가 아니라, 바이브코딩을 통해서 점차 개발자가 되어가는 기회가 된다는 점에서 새로운 시민 개발자의 시대를 그려볼 수 있게 됐습니다.

제임스님께서 어떻게 개발을 요청하고 문제를 해결하는지 과정을 엿보는 것만으로도 큰 도움이 되었습니다. 무엇보다 바이브코딩을 통한 첫 제품을 만들 수 있는 경험이 앞으로의 개발 도전에 큰 힘과 용기를 주었어요!
