I’ve finished developing my blog. The very blog I’m writing in right now. I named it Bug Loop. If someone asked me, “Why is it called Bug Loop?”, I would answer that I came to realize a simple truth: development = the loop of debugging. Being trapped in an endless loop of bugs, going “huh? what? wait... ugh…” repeatedly, relentlessly, endlessly. That, my friend, is development.

I’ve come to understand that development isn’t about a single grand, innovative idea, but about how sincerely you resolve countless small problems that nobody will ever notice... a cliché, but undeniably true.  

Why I Built It Myself

I’ve actually been interested in web development since 2022. 

And what’s the first step to starting anything? Buying books. (Yes, I am self-roasting here.) 

I bought a ton of books, and also found many free PDF resources online… but when it came to actually coding, I always felt overwhelmed and never took the step. I just kept reading. And reading. People say “you have to actually do it to learn,” but what can I say? My personality was like this: “I’ll start once I *feel* fully prepared.” That feeling, of course, never came. So I just kept reading. 

I let the dream of “I’ll learn web development someday” ferment deep inside me. In 2023, I briefly debuted as a pianist and hastily made a personal website using WordPress, then quit being a pianist just as quickly, left the site abandoned for a while... and only in 2025 did it finally hit me: ChatGPT could be an incredibly powerful tool for web development. Or rather, it’s not that I realized it late — it’s that ChatGPT’s performance had improved to the point where it could actually be useful for real development. 

When it comes to development, it’s not that I “don’t know anything.” I do understand the basics and the logic. But finding the cause of each problem, and figuring out the optimal solution, requires a huge amount of time and energy. I’m human — I have limits in parallel thinking. But AI can process knowledge rationally and efficiently, saving me from the sluggishness that emotions and fatigue cause. 

By leveraging AI, I drastically boosted my productivity, and the quiet fermentation of my desire for full-stack web development suddenly ignited into a flame. That’s how the development progressed so quickly.  

Because I’ve personally experienced how powerful AI can be in web development, I now understand when news articles say developer jobs are decreasing. Of course they are. Naturally...

Features and Tech Stack 

I really built everything from scratch, without relying on pre-made templates or components.

Features Implemented 

The editor I am currently writing this post in

• Custom editor for writing posts (probably what took the longest)
• Post view page (with floating table of contents button)
• E-book viewer page (created when shifting the blog’s identity toward being an e-book-focused blog)
• Sign-up system (currently disabled)
• Login
• Sticky label header
• Expandable/collapsible header panel
• Sidebar panel for profile display and post search
• Multi-language system (Korean, English, French, Chinese, Japanese, Spanish)
• Dark mode toggle

Tech Stack

These are the technologies I used:

Front-End

• HTML5 + EJS — multilingual and dynamic content rendering (EJS stands for Embedded JavaScript, meaning you can write JavaScript directly inside HTML, so pages are generated automatically as needed)
• CSS3 — responsive layouts, component styles, dark mode
• Vanilla JavaScript (ES6) — implemented all UI interactions manually (vanilla = nothing added)
• SVG — logo and character editing and animation (used while experimenting on another blog; I plan to use this more actively after studying Adobe properly) 

Back-End

• Node.js — server runtime (environment for running JavaScript on the server)
• Express.js — routing / sessions / middleware (handles which page to send for which request, login sessions, etc.) 
• bcrypt — password hashing
• multer — image upload handling

Database

• MySQL — storage for posts / users / categories / multilingual resources
• Handwritten SQL queries for CRUD operations

Deployment & Infrastructure

• Ubuntu Linux — server operating environment
• Nginx — reverse proxy + HTTPS
• PM2 — Node process management / zero-downtime execution
• Git + GitHub — version control and automated deployment
