Gemini's Development Practice - Commerce Backend Basics
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.

Portfolio guide from a CTO who has reviewed 10,000 applicants is now open!🔥
Hello! This is Gemini.
My final recruitment-related lecture! A Technical Director's Portfolio Guide After Reviewing 10,000 Applicants is now open!
📍Go to the Portfolio Guide by a CTO who has reviewed 10,000 applicants!!🔥
Course Introduction
Facts learned from 10,000 applicants
While there is no set formula for a successful portfolio,
portfolios that are read to the end have a clear reason for it.
Every developer has different experiences and charms.
However, many people fail to properly showcase their strengths because they simply list their blogs, GitHub, and side projects.
Based on what I've felt while reviewing over 10,000 applicants, I will point out the do's and don'ts, as well as the perspective of a reviewer when reading a portfolio, one by one.
What you will learn
Section 1. Things You Should Not Do
Applicants may think they are appealing to the reviewer, but there are things that actually result in point deductions. Before filling it up, we will first identify what needs to be removed.
Section 2. What to do
Portfolios that capture a reviewer's attention have commonalities. Establish criteria for what experiences to show and how to present them.
Section 3. The Reviewer's Perspective
What does a reviewer look at first, where do they pause, and why do they close the window? We reveal the exact differences between a portfolio that is read until the end and one that is just passed over.
Section 4. Appendix
After listening to everything, you're bound to have lingering concerns like, "My situation is a bit different..." I have selected and answered only the most frequently asked questions for each specific situation.
