ICT apprentice from Switzerland (ICT-Fachmann EFZ, 3rd year). At work I automate infrastructure with Terraform and Ansible for Proxmox and Azure. In my own time I build things to find out how they work underneath: a password manager with a post-quantum recovery key, hand-written physics engines, a browser shooter with time inversion, and macOS apps that talk to private system frameworks.
Most of my recent projects are built together with AI coding agents (Claude Code). I decide what gets built and how it should work, set the bar for "done", and test and review the result. Most READMEs say how the project was made.
- Now: infrastructure as code at work, a Windows version of Siegel at home
- Into: native macOS, security, simulation, automation, 3D

| Project | What it is | Built with |
|---|---|---|
| Siegel | Native macOS password manager with a local-only encrypted vault, Touch ID / QR key card / FIDO2 factors and a post-quantum hybrid recovery key (ML-KEM-1024 + X25519). 500+ tests and 20 hours of fuzzing, not audited. | Swift · SwiftUI · CryptoKit · libsodium |
| Dynamic Island | The iPhone's Dynamic Island wrapped around the real MacBook notch: Now Playing, live activities, and a Claude agent that can operate the Mac and asks before risky actions. | Swift · AppKit · private frameworks |
| STALSK-12 · play | Browser shooter about time inversion: one squad plays a mission forward, the other plays it backward. Own rigid-body physics, destructible buildings and a WebGL2 renderer, no dependencies. | JavaScript · WebGL2 |
| Pi-WoL · demo | A Raspberry Pi that wakes and shuts down my PCs over the network, with three themed control panels: supercar start button, cockpit and launch control. | Raspberry Pi · Python · Tailscale |
| Ship Sinking Physics · demo | Why ships sink: two hand-written 2D physics engines for buoyancy, stability, progressive flooding and hull failure. | JavaScript · Canvas |
| ScriptFlow · open | Turns PowerShell scripts into flowcharts, Nassi-Shneiderman diagrams and Mermaid code. Own parser, works offline, ships as one HTML file. | JavaScript · SVG |
| Windows 12 · open | A Windows-style desktop environment in the browser: window manager, virtual file system and built-in apps, no frameworks. | Vanilla JS |

Work for my employer and its clients stays internal, so the infrastructure side of my job is not on this profile. What you see here are my own projects.
