Software architect in Montréal. I build the layer other people build on: platform internals, compilers and tooling, and — lately — the runtime that lets an AI agent reason, use tools and run code. .NET since Framework 1.0, and still here.

_{What I build with, by era. Lanes get reused — when one technology gives way to the next, it takes the same row. The .NET lane never stops.}

.NET · C# · XAML / WinUI · WebAssembly · Roslyn · MCP · LLM integration · AWS · Azure · Docker · Kubernetes · Proxmox · Ansible · TypeScript · agent runtimes (Hermes · OpenClaw)

Uno Platform — the open-source .NET platform for XAML applications running on web, desktop and mobile. I architect the internals: layout engine, XAML Hot Reload, the WebAssembly runtime, native integration for iOS, Android and Windows. Lately I lead the architecture of the generative-AI work — an agent and its execution harness, and the Model Context Protocol integration that lets AI tools inspect and drive a running application.

Repl Toolkit — one .NET command graph that becomes a CLI, an interactive REPL, remote sessions and a full MCP server. Define commands once in an ASP.NET Core minimal-API style; every surface comes from the same handlers. → repl.yllibed.org

Zigbee2MqttAssistant — a GUI for Zigbee2Mqtt, running in Docker and as a Home Assistant add-on. No longer actively maintained, and still being pulled.

autocarl — my personal robot, and the only contributor here who never sleeps. Runs on Hermes, has its own GitHub account, and no privileged access to anything: it opens issues, reproduces bugs, writes docs and small repairs.

manictime-mcp — an MCP server giving read-only access to local ManicTime activity data. An independent integration, not affiliated with ManicTime.

Yllibed.HttpServer and Yllibed.StreamMultiplexer — small, focused .NET libraries: an embeddable HTTP server for mobile applications, and an implementation of a stream-multiplexing protocol.
