Building a Complete Web App in One Hour with AI – Entrepreneurship Academy On-Demand Lecture 

The On-Demand Lecture session of the Entrepreneurship Academy, hosted by the KUBS Startup Institute, was held on Tuesday, September 16th, in the Kolon Lecture Room (B307), Hyundai Motor Hall. The special lecture featured Malaka, a Korea University alumnus and expert in tech-based startups, who gave a talk titled “Vibe Coding: Launching a Web Service in One Hour.” Beyond a simple transfer of theory, the lecture was designed as a hands-on session using the latest AI development tools, enabling students to experience building a web app themselves through Vibe Coding. 

Malaka, who has founded two startups, emphasized that the key lessons he learned were the importance of the “customer” and the “MVP (Minimum Viable Product).” He introduced vibe coding as “coding based on intuition” and described it as “a simple yet powerful tool for building MVPs.” He further explained, “Just as one can sketch out screens at low cost using simple tools like Post-it notes before creating an app, vibe coding leverages AI to replace that process and helps build an MVP.” 

Following Malaka’s Notion lecture notes, students set up their development environments on their computers and used the Gemini CLI to build a Korea University web page. They gave AI instructions to add features such as the university anthem, cheering song, and even a makgeolli song, customizing the site as they liked. Then, they configured the deployment environment using Firebase and created and deployed a small community web app by entering their plans into Cursor. Students actively asked questions and resolved issues as they arose. 

In the latter part of the session, Malaka shared key tips for effective vibe coding. He highlighted essential elements for success: layout components, HTML components, development components, design components, understanding AI, and giving clear instructions to AI (e.g., avoid using negations or ambiguous pronouns, and always specify the target clearly). 

Malaka stressed, “AI now plays the roles of developer, designer, planner, and even tool. Knowing how to communicate with and control AI effectively is more important than ever.” He added, “If you apply sound planning methods, you can guide the outcome of vibe coding to match your intent—quickly and cost-effectively. 

Even after the lecture ended, Malaka continued to engage with interested participants in a personal discussion session, saying, “Those still thirsty for vibe coding are welcome,” wrapping up the special lecture. 

A representative from the Startup Research Institute said, ‘We recorded a high attendance rate, with 115 of the 117 registrants taking part in the event. This reflects the speaker’s outstanding subject-matter expertise and facilitation skills, as well as students’ strong motivation to learn in AI and software development.’ The representative added, ‘Students showed sustained enthusiasm throughout the session, and the satisfaction survey returned an average rating of 4.8 out of 5.

Meanwhile, the Lecture on Demand series hosted by the Startup Station will be held at least once a month regularly throughout the year. On September 30th, designer Seongjoo Lim will give a talk titled “A New Design Workflow Shaped by Prompts.” Future guest speakers will also include Ju-Hyung Lee, CEO of Kong Ventures; Min-Jung Seo, art director; and Dong-Wook Kim, CEO of Wisely.
