Designing a Data-Driven Job Search Strategy for Non-Majors — Hacking Job Hunting/Career Changes with Economics, Statistics, and AI

This is a practical portfolio guide shared directly by a CTO who has reviewed over 10,000 applicants. There is no such thing as a "guaranteed pass portfolio" or a "correct way to structure it" in this world. I will show you the reviewer's perspective: how they look at a portfolio, what they use to judge skill, and what content causes them fatigue. A portfolio is not simply about listing many items or decorating them flashily. The core of this lecture is understanding the process itself—properly organizing and communicating what problems you solved, and what you considered and chose during that process. Whether you are an experienced professional or a newcomer, this lecture will be helpful for any developer who has wondered how to organize and promote their portfolio, blog, GitHub, and side projects.

You can establish both the direction of your personal statement and the framework of your portfolio at the same time.

"Simply knowing technology well does not make you a good sales engineer."

Learn the work frameworks and mindset of a sales engineer that you can apply immediately in practice.

A practical side-project course for professionals who feel uneasy entrusting their career to just one company. By combining three elements—LinkedIn (trust), AI (productivity), and small products (validation)—you’ll build a version of yourself that works outside the company, too. Based on my own journey from 10 years at an advertising agency → 5 years as a data strategy leader → becoming an independent freelancer, I’ve organized everything into actionable steps you can start right after work: LinkedIn profile and writing routines, finding your selling points, five revenue models (courses/webinars · consulting/coaching · e-books/templates · partnerships/collaborations · communities/memberships), a worksheet for designing your first product, and sales channels and community operation funnels.

Have you ever been studying deep learning, only to lose sight of the bigger picture when model names and equations all appear at once? This course explains deep learning not as a collection of difficult formulas, but as the history of problem-solving that began with a single artificial neuron and progressed to ChatGPT. I have taught hundreds of hours of deep learning lectures to learners with diverse academic backgrounds and experiences at LG Electronics DX School. Through that process, I discovered a common difficulty: “I understand it while listening to the explanation, but when a new equation or model appears, I feel lost again.” So I improved the lectures by explaining what the problem was first, why existing methods failed, and what was changed to solve it—before covering the model’s structure or calculation methods. In this course, we follow a single visual metaphor—“drawing a line”—to connect the perceptron to CNNs, RNNs, Attention, Transformers, and large language models. Rather than calculating the equations directly, you will understand what problem each equation solves and learn to analyze new AI systems for yourself by asking the following question: “What problem was this model trying to solve, what did it change to do so, and what decisions did it leave to humans?” Ultimately, this course helps you develop the ability to distinguish between what should be entrusted to AI and what people must verify and take responsibility for, instead of blindly trusting or fearing AI.

If you receive stock recommendations from AI and leave the timing of buying and selling to it, will you actually make a profit? AI is not a prophetic tool that predicts future stock prices. Instead, it can be a powerful investment assistant that checks the emotions swaying your investment decisions, analyzes complex information, and helps you stick to long-term investment principles. In this course, you will understand the typical behavioral errors of individual investors—such as loss aversion, panic selling, and FOMO—and learn how to create unwavering investment criteria using AI prompts and investment analysis tools. From back-calculating target assets to portfolio design, utilizing tax-saving accounts, and setting up automated recurring purchases, complete your own AI investment system that even busy office workers can consistently execute. Point 1. Understand the limits of AI investment and use it properly Understand through data why AI is not suitable for stock recommendations and predicting trade timing Utilize AI in areas it excels at, such as earnings call analysis, ETF overlap diagnosis, and portfolio reviews Learn how to review counter-scenarios and risk factors so you don't just believe optimistic answers Point 2. Correct the malfunctions that sway investment psychology Diagnose recurring investment behavior patterns such as loss aversion, the disposition effect, panic selling, and FOMO Practice the 72-hour rule to reduce impulsive trading and routines for formalizing selling conditions Design AI prompts that help maintain long-term investment principles despite market volatility Point 3. Create a long-term investment system that sustains itself automatically Design a recurring investment plan and portfolio based on target assets and investment periods Review investment strategies through Monte Carlo analysis and tax-saving account simulations Complete an investment structure that executes without constant deliberation by setting up automated purchases and cash buffers
