I highly recommend Spring AI to developers using Spring Boot and React, as well as those considering the introduction of AI systems in corporate environments. This course goes beyond a simple introduction to libraries; it helps you understand the core concepts and internal structure of Spring AI, and strengthens your practical implementation skills through various hands-on examples. The course is based on Spring AI version 1.1.x and provides continuous technical support and expansion strategies to ensure you can adapt to future version upgrades. Furthermore, we expand the practical value of Spring AI technology by utilizing MCP (Model Context Protocol) to achieve cross-domain context integration, AI linkage in distributed environments, and AI architecture design suitable for enterprise environments. With the goal of building AI systems that can actually be deployed in corporate settings, this will serve as a practical guide that balances theory and hands-on experience.

This course focuses on the strategic application of Design Thinking for startups. It provides an in-depth look at the five-stage process of Design Thinking (Empathize, Define, Ideate, Prototype, and Test)—a human-centered innovation methodology—and teaches how to manage the uncertainties startups face while securing product-market fit. Additionally, the course explores integration strategies with Lean Startup and Agile methodologies and analyzes successful domestic and international startup cases such as Airbnb, Netflix, Toss, and Baedal Minjok. By covering a wide range of topics, including measuring the financial value of Design Thinking (ROI, KPI), strategies for organizational adoption, and the future outlook of Design Thinking combined with Artificial Intelligence (AI), this course helps strengthen practical business innovation capabilities.
