LEE SEOKHYUNG · BUILD & VERIFY
Build, run, and
verify it yourself.
Hello. I’m Seokhyung Lee, sharing what I learn by designing circuits and building web services with AI. I enjoy the process of learning by understanding the principles, creating small projects, and fixing anything that differs from what I expected.
A course where you can explain what you are building right now
and how far you have verified it.
01. From Circuit Principles to Real-World Design
I designed a 12-bit SAR ADC myself and gained experience with LVS/DRC verification and the chip fabrication process. Even designs that look correct in the schematic can encounter new problems during implementation and verification. Based on that experience, I explain the operation and signal flow of analog circuits, along with the fundamentals that lead into digital and ASIC design.
02. Building a Web Service and Fixing Errors
While building FactRaptor, we covered article content extraction, login, screen layout, and QA step by step. When extraction failed or settings were misaligned, we focused on reproducing the problem, narrowing down the cause, and checking again. The course also includes problems encountered during actual work and the recovery process.
03. Hands-On Practice Implementing Directly with AI
In the course using Astra and Codex, you’ll define a small feature, ask for its implementation with a prompt, and then check the result in the browser. We provide prompts you can copy and use for the exercises, diagrams that help you understand the structure, and materials for each session so you can carry the work forward into your own project.
A Collaborative Learning Approach
Understand — See how inputs, processing, and results are connected.
Building — Implement a small feature yourself.
Check — Run the normal flow and failure scenarios in practice.
Fixing — Check the changed result and move on to the next task.
For those curious about how signals flow through a circuit, and those who want to turn AI-generated screens into a working service, we’ll learn together. Rather than rushing to complete everything at once, let’s start by building up the experience of directly verifying one small result.
