I live in Basel and work as an AI architect. By day I am Enterprise Solution Architect for AI Platforms and Agentic AI at Helvetia Baloise Group, helping define a Group-wide platform for the secure, governed use of foundation models, agents, and AI-assisted engineering.
The rest of the time I build things. For years my ideas lived in a notebook because there was never enough time to try them. AI changed that: the bottleneck moved from writing the code to deciding what is worth building. So now I try a lot of ideas, ship them in small and real form, and see which ones stick. Some become serious projects. Some stay fun. Both are fine.
It all lives under raskell.io (raskell = rascal × Haskell × Raffael, tanuki mascot included). Tech that serves humans. Boring by default, precise when required.

Most of what I build falls into three threads. The same habits run through all of them: open standards, sane defaults, and systems that keep working when reality shows up.
Where I have spent most of my career: reverse proxies, WAFs, and the traffic in between.
- Zentinel (GitHub): a security-first reverse proxy on Cloudflare Pingora, with isolated security agents, SDKs in 7 languages, a pure Rust ModSecurity engine, and a fleet control plane. My most-used project.
- Vela: no-downtime app deployment on bare metal. One binary, no containers. It runs my own apps in production.
Compilers, package managers, frameworks, and specs. The tools I wish existed.
- Arcanist.sh: Haskell tooling built in Rust. hx is a fast package and project manager; bhc is an alternative compiler with runtime profiles and tensor-native numerics.
- Refrakt (GitHub): a convention-first web framework for Gleam.
- WASM-AD (GitHub): a fantasy console standard whose cartridges are WebAssembly modules, with a spec, reference renderer, and SDK.
- seijaku: 静寂 the zero-JavaScript Zola theme behind raskell.io.
Small things you can open right now. Your data stays on your device; the simulations and games run in the browser.
- Kurumi: a local-first, AI-native second brain that works offline.
- Manabi: 学 a reading-first language-learning app for Chinese, Japanese, and Hebrew.
- Paw & Claw: turn-based tactics in the spirit of Advance Wars, fought by woodland armies.
- Rainbow River: a handheld-era fishing game, and the first WASM-AD cartridge.
- Terrarium: a simulation where LLM-powered agents form emergent societies.
- broodwar.live: the community platform for StarCraft: Brood War, with replay analysis in the browser.
Early-stage ventures, built toward products and communities. I am talking to early users and investors to see how the market responds. If one of these interests you, get in touch.
- Archipelag.io: decentralized AI compute on community-operated GPU hosts. I am the founder.
- Cyanea: an open community for life science research, with Rust analysis tools in the browser.
- Humankind: a consent-first archive of a person's voice, stories, and values across generations.
Experiments that are early, paused, or waiting for their moment: coconutOS (a GPU-isolating microkernel) · Kage (shadow agents for code work) · Conflux (CRDT config coordination) · Shiioo (an agentic company OS) · Ushio (WAF traffic replay) · Sango (edge diagnostics) · Human Macroscope (research on human collectives) · Die Zukunft (engineering principles for public life) · Driftscape · robogym
I write about platform automation, edge systems, applied security, and what changes when AI writes most of the code, including The Agent Platform Handbook and Learn You the Web.
