My First Web Service Created with AI: From Deployment to Payment and Operations Without Coding

Many office workers are failing to properly protect their hard-earned money because they miss out on refunds they didn't know about or pay more in taxes than necessary. Studying taxes is not about memorizing difficult legal knowledge. It is the most practical form of financial management—understanding your pay stub and protecting your own money. In this lecture, we will cover the core tax strategies for office workers to actually save money and build assets, ranging from year-end tax adjustments to income management and tax-saving accounts. Point 1. How to protect your salary through year-end tax adjustments - Understanding tax-free items and deduction structures in your pay stub - Year-end tax adjustment strategies to increase refunds, such as personal and housing deductions Point 2. Tax strategies for managing income safely - Understanding the tax structure you need to know when additional income occurs - How to legally save on taxes when filing global income tax Point 3. "Tax-tech" strategies to build assets using taxes - How to utilize tax-saving accounts like ISA, IRP, and pension savings - Investment tax management strategies to increase after-tax returns

The most rapidly emerging task automation tool recently is 'Claude Code.'

Investing is not a gamble that should come at the sacrifice of your career, health, or family. This process will teach you how to build a reliable 'automated investment system' so that you don't waste precious time trying to time the market or getting swayed by its volatility. The core is simple: 'discarding market timing,' 'DCA automated investing,' and 'long-term investing for over 10 years.' You can experience the magic of compounding through DCA by consistently investing in high-quality assets over the long term. Point 1. A long-term investment system built with blue-chip US stocks and ETFs - Understand how to construct a portfolio centered on top-tier US stocks (TOP9) and ETFs - Build an investment structure that remains unshaken by market timing through DCA (Dollar Cost Averaging) Point 2. Long-term investment strategies to maximize the power of compounding - Understand the significance of long-term investing for over 10 years and the principles of compound growth - Correct common investment misconceptions regarding inflation risks and loss of principal Point 3. Investment strategies completed with tax-efficient accounts for employees - Summary of key benefits of tax-efficient accounts such as Pension Savings, IRP, and ISA - Understand practical investment strategies using US ETFs listed on the domestic market

Are you using AI but still unable to get it to do the work for you? This course is not just about simple usage; it is a process of creating your own "high-performing AI assistant."

This course is a lecture that focuses more on 'what attitude to invest with' rather than 'which stocks to buy.' Through questions from Ahn Seung-chan, who runs the 1.3 million-subscriber YouTube channel <Understanding: All the Knowledge in the World,> and answers from Kim Hak-kyun, a 30-year veteran analyst and Head of Research at Shinyoung Securities, we deliver the most important criteria for investing. Center Head Kim Hak-kyun, who has experienced both market booms and crashes for over 30 years, organizes the investor's mindset based on practical experience—covering the history of stock indices, human investment psychology, the power of compound interest, and investment habits that never fail. This course is not about flashy techniques, but a process of building investment principles for long-term survival.

This lecture does not view investment as a matter of "stock picking," but rather starts from understanding how asset prices have been formed and changed over the long term. It summarizes the essence of the 21st-century investment environment, created by the combination of ultra-long-term asset price trends, changes in currency value, and the structure of technology and hegemony. It provides investment criteria based on the shifts of the era, enabling individual investors to make judgments without being swayed by short-term trends, even in a highly volatile environment.

Wars, conflicts, and shifts in alliances happening around the world are no longer stories of distant lands. We are now in an era where these changes directly impact exchange rates, interest rates, industries, and the personal investment environment. Instead of consuming international affairs as "difficult news," this lecture starts by understanding why these conflicts recur and where capital moves as a result. To ensure that individual investors do not lose their way amidst global uncertainty, Professor Park Jung-ho provides an investor's perspective on reading the world order.

Dozens of economic news stories pour out every day, but it is not easy to determine what they actually mean for your salary and assets.

It’s okay if you don’t know how to code. This course focuses on the experience of using AI to build an ad-revenue-generating Android app from scratch and successfully launching it in just one day. Many people stop at these stages: “I built the app, but how do I monetize it?” “I tried adding ads but got stuck on AdMob, policies, and reviews.” “I gave up right before launch because of the privacy policy.” In this course, we will navigate through every "drop-off point": 👉 Idea → App Creation → Ad Integration → Store Launch Essentials → Actual Deployment. We let the AI do the work, and we make the decisions. The goal is to complete an app with a "functioning revenue structure" within a single day.
