When you play table tennis with someone, you can immediately tell whether they have true depth of skill. When playing with someone who is good at table tennis, you can learn not just from their skill but from the look in their eyes. That look of complete immersion -- shutting out everything else and focusing entirely on the game.
I am not yet great at my own language, but I believe that after a few conversations, you can sense a person's skill and depth in language as well. Like Lee Hayoung, the author of "I Respect My Twenties the Most," who went through the process of reading books, organizing thoughts, and crafting her own words -- there is a clear difference between someone who has gone through that process and someone who has not. I am not talking about speaking eloquently. I am talking about speaking with sincerity, not falsehood, rooted in one's own experience and thinking.
The same goes for developers. There is a definite difference between someone who has broken through countless difficult situations and someone who has not. Every time...
The difference between 2,500 points and 3,000 points may not look like much on the surface, but the gap in skill and depth is beyond imagination. To reach that level...
Why Should I Resign?
An Environment Where I Cannot Focus on Life
I think I am inherently slow at context switching. However, I believe that when I am immersed in one thing, I can dive deeper than anyone. That is why, in the past during table tennis matches, I often could not focus on the most important games, getting shaken by the words or gazes of people around me, and ended up accomplishing nothing. While on on-call duty, my focus breaks at the moments when I need to concentrate the most...
On-call Duty
I Want to Build Real Skills
I want to study English, algorithms, and data engineering knowledge intensely in a short period of time. And I want to properly challenge myself at a better company.
What Did I Learn?
There are several things that gave me insights during my time at the company. Looking back, most of them came from people, and these experiences are very precious.
- Kiyong Han's lecture ("Failure Is a Compass")
- EJ's management special lecture
- How to report well
- Underestimate your boss's memory, overestimate your boss's intuition
- Writing wiki documents
- Junghoon
- How to speak well and write good documents
- How to brand yourself smoothly and give the impression that you are good at your job
- Jungmu
- The thought that I need to become more humble
- Could I have shown that same kind of behavior?
- CI/CD
- Hosu's FastCampus lecture
- Jongho's management skills and mindset toward documentation (readability)
- Learning about Heeseung Lee, who created Armeria and the open-source Jetty
- Experience developing web backend and frontend with React and Python3 Django
- Dongeui's troubleshooting ability
- Jonggyun
- Eloquence, judgment, and the inclusiveness to embrace everyone
- Japanese proficiency
- Understanding of people
- Feedback that genuinely helps the person
- Honesty. Sincerity.
- For engineers, it is skill first and skill second. Without skill, people become petty and do ugly things. A lesson learned from observing others.
- Having done the LINER View filming
- Execution is what matters
- Meeting Shinken-san and Kkudeok-san
- The pulling power of a fun and humorous person
Are There No Risks?
- Can I do well at another company too?
Another reason I am resigning is that my skills are not overwhelmingly strong. I seem to have a bit of an academic background complex, and I lack confidence in English, Japanese, and algorithms. This was my first company, but let me take everything I should take with me.
- How to write documents
- How good do you need to be at languages?
- How to report, and what mindset to have for company life?
- Making your boss and colleagues shine
- Recording, sharing, and being someone who multiplies rather than just adds
- Can I push myself to grow without being at a company?
I cannot guarantee this. However, if the goal is clear, I am confident in running toward it. But I need to do it the right way. With AI advancing rapidly, the domain where a solo developer can operate is increasingly...
- AI-powered automatic table tennis score calculator (this would be enough)
- Sports experience web platform for travelers
- Build free websites for them and make it easy to book
- Table tennis VR content (Eleven)
- Creating outstanding development courses like Nomad Coder
- Will I get employed again? Is what I truly want actually entrepreneurship?
If I start a business, let me set a timeframe and launch one service per month, putting out ten total, and if there are no results from that process, go back to employment. Entrepreneurship is truly hard, and it is not something done by people who cannot get a job -- it is for people whose potential cannot be contained by a company and who must venture into a wider world.
Things I Think Need to Change
- Writing documents
I have often used the excuse of developing alone and needing to develop quickly as a reason not to create proper documentation. At some point, when collaboration is needed, someone else will need to touch my code, and I should leave room for them to easily modify and further develop it.
- Writing clean code with comments
Just like point 1, developers should show themselves through their code. Projects that help others and are admirable have soul poured into every single line of code. Let me become someone with felt depth, like Jungeun Choi. Jungeun Choi
- Language study methods
- Verify my skills at Toastmasters
-
Have confidence
-
Rather than fact-based conversation, have conversations that consider people's feelings
- I find stability in people who are embracing and make you feel warmth
- Read many books and make them my own
What Do I Want to Do?
- After all, I think development is what I enjoy the most.
- I seem to have a really strong desire for growth!
