Background

Z80 assembler on a ZX Spectrum. A degree in Physics. Particle detector simulations at CERN. A PhD on stochastic neural networks at ETH Zürich. Software companies in finance, manufacturing, and AI. The common thread: computation that ships. Currently building LLM-powered agents delivered entirely through email.

Experience

PhD in computational neuroscience, ETH Zürich's Institute for Neuroinformatics. Publications on Nature Biotechnology, Biotechnology Progress, Biological Cybernetics. Earlier at ETH: robotics, gene and biochemical network modelling. Before that, particle detector work at CERN.

Founded and led several software companies: derivatives pricing algorithms, IoT architecture for medical devices, machine-learning-based text-analytics engine, e-commerce platform for 3D-printing bureaus. In between: financial risk consulting at Oliver Wyman.

Now: LLM-powered services delivered entirely through email. Silex is the infrastructure platform. Aleik is the first product running on it.

Silex

The platform for LLM-powered email-based services.

Silex lets you build intelligent, conversational services that run entirely through email — no app, no login, no installation required. It handles LLM orchestration, conversation memory, human approval workflows, and logging, on proven infrastructure built with Erlang, Elixir, and PostgreSQL.

Aleik

Science finds the story. You tell it. We write it.

Aleik surfaces new scientific research as weekly email digests, lets writers choose a story angle by reply, and delivers a publication-ready article — fully sourced, SEO-optimised, written in the subscriber's own voice. The entire workflow runs through email. Built on Silex.

Beyond the Brain: A Study on Consciousness in Unconventional Places — and What It Means for AI

If minds are not the exclusive property of brains, the carbon/silicon line stops being the interesting one. On Rouleau and Levin’s continuity argument, the gap Be Right Back is really about, and what testing can and cannot see.

When the Simulation Passes the Test

If an AI persona could produce the same behavioural variation as a human tester, would the practical advantage of human testing disappear? On Lem’s Electronic Bard, Searle’s Chinese Room, and the bet underneath the methodology.

Testing AI Agents Like You Mean It

Eight methods for testing AI agents — from persona-based and contract testing to mutation, regression, and human red-teaming — organised into three tiers of evaluation difficulty.

AI Doesn’t Have Opinions

The model didn’t change its mind — it has no mind to change. On sampling, anthropomorphism, and treating system prompts as code.

From Python to Elixir for AI Agents

Why I converted most of my AI code from Python to Elixir — preemptive scheduling, supervision trees, and clean retry semantics for LLM-driven systems.

Email Is Not Broken — It’s the API You Already Have

Every year someone announces the death of email. What if its universality is exactly what makes it the most interesting deployment surface for AI agents?

Why Fully Autonomous AI Agents Should Not Be Developed

A Hugging Face study argues the risks of fully autonomous AI agents significantly outweigh the benefits — and makes the case for keeping humans in the loop.
