Ghost in the N8N (AI Automation Workflow)

CI/CD environment is indispensable in modern project development. Let's become a (real) deployment fairy with TeamCity, the most widely used tool in the field!!

In just 2 hours of hands-on practice, we build a local LLM with RAG-based QA system using the Docker + ollama + R2R framework. (Internal/in-house QA systems, personal portfolios, AI-powered work capabilities, and even commercial services are possible.)

"Level Up Your Python Alone!" Starting from Python basics, all the way to creating 2D games and an Ollama-based AI chatbot! This is a practice-focused introductory course where you learn core syntax like variables, conditional statements, and functions, and improve your skills by building things yourself.

This lecture aims to be a welcome resource for those who dream of becoming game programmers. 1) We share tips on resumes & cover letters, portfolios, and interviews needed for employment. 2) We share the story that continues from zero, through becoming a junior, and beyond.

We introduce a DevOps lecture based on practical cases experienced directly on the front lines of Silicon Valley. This lecture does not just stick to theory, but covers CI/CD related tools in a K8S environment that can be applied directly to actual engineering sites.

I've created an introductory CI/CD course that's easy for non-majors to grasp and immediately applicable in practice!

If you want to properly learn OCR technology that's truly used in practice, this one course is all you need! Aiming for over 98% accuracy even with unstructured documents and complex layouts, based on the latest SOTA models and real-world know-how, we build enterprise-level OCR projects together.

This course, Part3 of the Full-stack Course Series, solidly teaches the latest server and Docker technologies. It's structured to practically integrate Docker into your tech stack, meticulously testing its options, learning necessary related tech like Linux, and building complex services.

Packed with LLM Fine-Tuning Know-how, learned from Silicon Valley LLM Project Practitioners.

Forget boring theories! We're going straight into practice from the beginning of the lecture. Once you start, you'll be captivated by the charm of Excel Macro VBA that you won't be able to stop~!

Learn Macro VBA with Excel 2019!! However, you can also practice with 2016 and 2013 versions. Macros and VBA fill in the gaps that Excel alone lacks.

“The era of merely asking AI and getting answers is over.” Now, AI acts on its own. 'Action-oriented AI agents' have emerged that read emails, check remaining annual leave in HR systems, schedule meetings, search internal documents to summarize information, and organize necessary images and links. What's surprising is that all of this can be created even if you're not a developer. By leveraging the Azure AI Agent platform and Microsoft's latest frameworks (Semantic Kernel, AutoGen, etc.), anyone can now build multi-agent systems deployable in actual work, without coding. Directly create 'working AI,' 'connected AI,' and 'AI that judges and moves on its own.' The future is no longer a distant story. It begins now, at your fingertips.

No more lectures that start with boring grammar! Python practical application examples that jump straight into use

This course is designed to help you quickly learn server zero-downtime deployment methods using Nginx, Docker, and Spring Boot through hands-on practice. Learn Blue-Green deployment, which is frequently used in real-world scenarios, faster than anyone else!
