MIXUTIN / PORTFOLIO
Curiosity is
the common thread.
I am Mikael Nurminen, known online as mixutin and 0x11a. I work at the intersection of security, systems and software preservation.
BEHIND / 0x11a
Taking things apart.
Making things possible.
My favourite part of a problem is finding out how it really works. That might mean studying a cipher, reading machine code or tracing what a game client expects from a server.
Game and media preservation matter to me. Software should not disappear just because a service goes offline. I also build native desktop tools, backends and systems-level experiments.
CTF competitions keep me learning. Open-source projects give those ideas somewhere practical to go.
TOOLKIT /
Different tools. One mindset.
Systems & desktop
Rust · C · C++ · Swift · Linux · macOS · UEFI · QEMU · Tauri
Backends & creative tools
TypeScript · Node.js · SQLite · GitHub Actions · Unity · Roblox · Blender · MCP
WORKFLOW /
Build. Test. Understand.
I use AI-assisted development alongside debugging, testing and direct inspection of the code. A good-looking interface or a green build is a starting point, not proof that every feature works.
Make the state visible
Document what works, what has been tested and what is still planned.
Preserve the useful parts
Keep provenance, upstream credit and practical documentation close to the code.

Something worth building?
An interesting security problem, an open-source idea, or a game worth preserving. Let's talk.
