Gemini's Development Practice - Commerce Backend Basics

This is a practical technical interview strategy lecture shared directly by a Technical Director who has conducted over N,000 technical interviews. There is no such thing as a "guaranteed way to pass" or a "guaranteed formula for success" in this world. I will show you the interviewer's perspective—how they perceive a resume during the preparation stage, and what they focus on and prioritize during the interview process. A technical interview is not a memorization subject with fixed answers. The core of this lecture is understanding the essence of the process itself: showing your true self to the interviewer and persuading them. Whether you are an experienced professional or a newcomer, this lecture will be helpful for any developer who has ever worried about technical interviews.

This is a practical resume writing strategy lecture shared directly by a Technical Director who has reviewed over 10,000 resumes. There is no such thing as a "guaranteed pass template" or a "must-pass formula" in this world. I will show you the perspective of a document reviewer—how they read resumes, what they focus on, and what makes them feel fatigued. A resume is not a subject for memorization. The core of this lecture is understanding the process itself of properly organizing and expressing who you are. Whether you are an experienced professional or a newcomer, this lecture will be helpful for any developer who has ever struggled with their resume.

"In the era of AI, what should developers do?" To answer this question, former Toss Payments Technical Director Jaemin Kim and Inflab CTO Hyangro share their insights. Beyond flashy technologies, discover the most practical answers on 'how to grow steadily within your given environment'!

Because you never know when or how software will grow, you always need to be prepared to continue growing. This provides one direction for that.

With the arrival of the AI era, the skills required of developers are becoming increasingly complex. You might have thought, "I just need to be good at frontend," but when you try to create your own service or integrate AI features, you eventually hit a massive wall called the backend. However, as you try to start backend development, are you overwhelmed by how much there is to learn—from database design and authentication (Auth) to storage management and complex infrastructure setup? Now, you can lay down that heavy burden. In this course, we use Supabase, which solves all these backend functions at once. We will guide you through the fastest shortcut to becoming a full-stack developer who can "instantly" complete a backend without complex server knowledge and bring ideas to life immediately.

[Only for those new to web development] Spring Boot REST API: Building step-by-step while properly understanding JPA

Learn the fundamentals of SQL and databases essential for practical work. Not only developers, but also planners and data analysts can learn SQL in depth.

[TPC DB!] A course that allows you to learn database modeling while thinking, learn database modeling step by step, and master everything from database modeling to web programming implementation all at once.

Through this course, you can learn SQL and database fundamentals, SQL syntax, database design for practical applications, database utilization through programming, and data analysis use cases.

This course focuses more on data modeling through entity design than on JPA technical explanations. Based on the principle that solid DB design is the foundation of application development, we analyze various design patterns—such as one-to-many, many-to-many, inheritance, and collections—alongside business scenarios. You will learn by directly observing the process of code being transformed into actual tables on screen. To ensure immediate practical application, we provide business use cases, source code, and test codes for each design pattern.

Just listen. The lecturing skill, captivating power, and lecture quality are different.

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.
