Hi, I’m Leejun Kim and welcome to my digital garden! I’m a SWE with a focus on backend and AI. I’m a pretty (very) forgetful person and I usually forget what I learned, so I try to fix that by taking notes as much as I can.. feel free to hop around!

Note
this digital garden is under major construction - there are TONS of messy screenshots/notes scattered everywhere, just a small warning ☠️
- 2/12/26 - This place was originally just used to take down notes of tech study sessions, but I decided to make a better use of obsidian and write down more bout different things as well (project documentation, thoughts, devlogs, non-tech stuffs).
- so the main blog will be curated posts that will be longer? and obsidian will consist of smaller connected notes.. im still figuring out which posts should be in which category.
- documenting everything helps
