6 Hyukjin An — Software & Security Engineer, and a founder, based in South Korea.
7 I'm a pig who loves coding and happens to be a weeb.
8 That's why I go by **debuman** online.

10 I like having a hand in the whole lifecycle of a service, from the hardware and the
11 systems underneath it through DevSecOps and on to planning and writing the thing. That
12 has taken me through enterprise infrastructure, SysOps, full-stack development and
13 security engineering; these days I work as a software engineer inside the security
14 domain. I started out as a developer, so my languages are C++, Rust and Python, and I
15 spend a lot of my open-source time building the tools security testing actually needs
16 and contributing to other people's. Right now most of my attention goes to OPSEC and
17 zero trust.

19 The rest of my time goes to running my own things. As a solo founder that means
20 reviewing the services I already have, launching new ones, and doing every other job
21 myself — finding the business model, handling the legal side, working out how anyone is
22 supposed to hear about it.

24 Hardware is part of the fun. My first homelab ran on a Dell PowerEdge R650; now it is a
25 Lenovo ThinkStation P3 Tower under Proxmox. Day to day I work on a ThinkPad X1 Carbon
26 Gen 13 Aura Edition running Arch Linux, in Ghostty and NeoVIM, with Codex CLI and Claude
27 Code alongside.

29 What I write is under [writing](/writing/), and the tools I have published are under
30 [code](/code/) — including [sqzass](https://github.com/debuman/sqzass), the static site
31 generator that builds [sqzer.com](https://sqzer.com/). There is more on
32 [GitHub](https://oni.sqzer.com), a service of mine at
33 [lacrymaria.com](https://lacrymaria.com), and I am on
34 [LinkedIn](https://www.linkedin.com/in/sqzer). Mail reaches me at
