[VOD] The Reality of the 2026 Developer Job Market: How to Find Opportunities in 'Legacy'

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.

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 course focuses on building the real skills needed in actual development work. The goal is not simply to learn how to write code well, but to experience how to work well as a developer. The examples are based on the commerce domain, covering cases frequently encountered in real-world work environments, and are provided in SpringBoot & Kotlin. However, it's a course where anyone can contemplate and experience real-world development through thought-provoking content, without being dependent on any specific language or framework. Based on the practical perspective of a senior developer and former director at Toss Payments who led a large-scale payment service organization, the course is designed to help you learn the thought processes and design decisions used in actual work environments.

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.

Messy code, a flood of requirements... If you're looking for a breakthrough with AI, Learn how to become a "high-performing developer" by leveraging AI in legacy environments, taught by the former VP of Engineering at Toss Payments. Legacy code isn't going anywhere, even in the age of AI. It’s no exaggeration to say that every company has legacy code, unless they were founded today. So, how should we utilize AI in this reality? In this course, the former VP of Engineering at Toss Payments, who led a large-scale payment service organization, demonstrates firsthand how to work effectively using AI in legacy environments. This isn't just a course about how to use AI or basic coding skills. The goal is to help you develop your "critical thinking" as a developer and truly understand what it means to work effectively.

You can learn about Text-to-SQL systems that generate and query SQL statements in real time in response to user questions.

If you're confident in development but your resume is bland, you need this course now. Using OOOO + practical revision examples, you will directly write resumes that technical interviewers will be curious about.

We will summarize all the hot topics regarding Generative AI, LLMs, and Agents from throughout 2025! Focusing on the announcements from the three major AI developers (OpenAI, Google, and Anthropic), we will take a look at the trends of AI that have advanced remarkably in '25.

Listening to the interview speech can help you pass the interview with flying colors.

Hundreds of saved materials, but zero materials opened again. Materials that are just piled up and never looked at. Are you perhaps doing the same? We're sharing a case study of someone who built their own OS to solve this problem.

The real story of an AI-native company run by GolbinHacker, the 1st place winner of Kakao AI TOP 100 and author of the bestseller "The Best Prompt Engineering Lecture." It explores how just two developers build and operate a service, along with the new competencies developers and organizations need in the AI era through real-world cases.

Beyond the basics of API design, CRUD implementation, and JWT authentication, all the way to backend architecture design! This is an introductory system design course to help you create 'your own backend architecture' so you can confidently discuss design experience in interviews.

Learn how to turn a vague idea into a "completable work." The reason you fail to finish writing on your own is not a lack of talent, but a lack of planning, structure, genre, and scene-level design. Based on my Master of Fine Arts (MFA) in Screenwriting, over 10 years of writing experience, and the achievement of winning two awards with a single work, I will organize professional-standard writing techniques step-by-step online. In this main lecture, "Chapter 1: Film Planning," we will cover everything from planning methodologies to writing loglines and statements of intent, while also learning prompt engineering to utilize AI as a planning and assistant writer. Ultimately, you will work with the instructor to complete a one-sentence logline for the project you wish to write. The course proceeds with the perspective that the writer's judgment and design are what matter most, while AI is simply a tool that makes that process more efficient. The full curriculum for [Film and Drama Storytelling in the AI Era: Story Design for Creating Works and Careers] follows a 5-chapter roadmap: Film Planning → Structure → Plot & Character → Genre → Scene & Adaptation. By following each step, you can eventually expand your work into a full-length feature film screenplay (or a series proposal + scripts for episodes 1-2, depending on your goal). (Note: This course is sold individually by chapter.)

This is a recording of a meetup with CEO Yongho Ha, who has been at the center of the AI evolution—from starting as a first-generation data scientist to achieving two machine learning startup exits and serving on the National AI Strategy Committee. Have you ever felt that the more you use AI, the more unclear your own expertise becomes? We’ve all been there. This anxiety stems from "Workslop" and the technical, cognitive, and intentional debt that accumulates without us even realizing it. This meetup begins by diagnosing the true nature of this anxiety and moves on to practical discussions for working with stability—covering everything from verification skills and structural design to learning methods for building your own criteria for judgment.

This introductory course is designed to help even those new to UX/UI design systematically understand the basic design workflow and build the foundational skills required in the field. Even as AI is utilized in the design process, designers must possess fundamental UX design competencies to maintain long-term competitiveness. This course is structured to help you master those basics step-by-step, more thoroughly than any other course.

We will build 'Kagong Map'—a service I personally operate—from scratch, learning the entire real-world workflow from research and development to deployment, operations, and even automation by delegating tasks to AI agents. And I promise you two things: first, you will grasp the big picture of how a service works so you can evaluate AI outputs yourself; second, you will learn to embed workflows and standards into the environment so that AI produces consistent results every time. When you can make the judgments and the AI follows your lead, your ideas truly become real services.
