Rough History

1. About 10 years ago

   Became interested in cybersecurity

   I noticed how often cybersecurity was appearing in the news, so I went to the information security section of a neighborhood bookstore. It was a big, quiet shop with classical music playing and not many customers. I picked up a book, browsed a few that looked interesting, bought one, and started reading.

2. About 10 years ago

   Started making games in Unity with a friend

   GTA V was everywhere, and I wanted to play it too, but it was expensive. So I thought, 'If I make something like this myself, it is free,' bought a book, and started learning with a friend. We ended up making something like an obstacle-course game.

3. About 5 years ago

   Started building native apps with Python

   I wanted to learn Python, but simply studying syntax did not feel very exciting. With a learn-by-building approach, I used Python books and online articles as references and started making native applications.

4. About 5 years ago

   Started experimenting with 3D printers

   Affordable 3D printers were becoming popular, so I bought one out of curiosity. I made cable holders and various small things, but the smartphone stand turned out especially well, and I still use it today.

5. About 5 years ago – present

   Started studying security seriously

   I began studying security in earnest through hands-on practice and CTFs, gradually building more systematic knowledge.

6. About 4 years ago

   Started building web apps with Python

   After building a few things, I wanted other people to see them, so I shifted toward web applications that were easier to publish. Django looked promising, so I built and released an app with it.

7. About 3 years ago

   The beginning of the generative AI era

   People on X were saying that something called ChatGPT 3.5, released the day before, was incredible. I tried it right away, and it really was. I gradually started incorporating it into self-study and coding.

8. About 3 years ago – present

   Ran Django workshops

   I helped build a community for making web apps and, after becoming its lead, ran regular Django workshops for two years. We had around 10 to 20 participants and kept it fun. The lead role has long since passed on, but I am still involved.

9. About 3 years ago – present

   Security research

   I am currently doing research while analyzing attack logs, experimenting with machine learning, designing new architectures, and presenting at academic conferences.
