New Course Now Open — “The Developer Who Documents: Running a Tistory Tech Blog from A to Z”

Hello, I’m Jjanggu (may9noy).

I’ve opened the new course I’ve been preparing for a long time today.

Creating a blog takes just 10 minutes. The question is whether you’ll still be writing three months later.

Over the past 8 years, I’ve written 1,211 posts on Tistory, and the cumulative number of visitors has reached 570,000. I’ve never run ads or participated in reciprocal promotion. Most visitors came through search.

This course was created by reverse-engineering those eight years. Rather than focusing on how to create a blog, it focuses on how to keep going.

Recommended for people like this

  • Those who want to start a technical blog but are stuck on their first post

  • Those who created a blog but have left it abandoned for several months

  • Those who feel discouraged because they write posts but no one reads them

  • Those who want to document their technical work for a career change or portfolio.

What We’ll Create Together in the Course

  • A category structure that holds up even after surpassing 1,000 posts

  • A collection routine that never runs out of topics and the "trial-and-error log" technique

  • Reusable article templates and a 30-minute publishing workflow

  • Google Search Console Integration and Indexing Request (We’ll Do It Together While Looking at the Screen)

  • A weekly publishing rhythm and backup system you can maintain without burnout

  • How to Use Your Blog Effectively in Resumes and Interviews

I don’t exaggerate AdSense earnings. For 1,000 posts, a monthly income of 10,000–30,000 won is the reality of a tech blog, and I tell you exactly that in the course as well.

📦 I’m providing article templates, a collection of head tags, and a 30-day action plan for free as course materials.

Even 1,211 posts started with a first post that had just 3 views. Two of those were from me checking it myself. Your first post can be enough for today, too.
