Yubico.NET.SDK
The official .NET SDK for YubiKey. I work on it daily — releases, CI hardening, cross-platform reliability, and the developer experience around strong authentication.
Engineering
Systems that return power to the person using them.
Senior Software Engineer at Yubico, with 10+ years across authentication, media platforms, developer tooling, CI/CD, and full-stack systems.
Current role
At Yubico I work on cross-platform authentication SDKs and developer infrastructure. The practical work is code, APIs, releases, CI hardening, and documentation. The deeper work is making strong authentication easier to adopt without hiding the important edges.
What kind of engineering matters here
I am drawn to security, open systems, local-first tools, and infrastructure that gives users more agency instead of more dependency. Good software should feel boring in production and liberating in use.
Highlight projects

Personal AI infrastructure for memory, agent workflows, publishing, and sovereignty-oriented automation. My fork of the PAI framework, customised around Sia as my daily AI peer.
github ↗Speaksheet
A chord-sheet app for gigging musicians and worship leaders — Svelte 5 + Capacitor, preparing for the Play Store. The codebase that produced the AI-routing essay on the blog.

github ↗Stack
C# / .NET, TypeScript, Astro, React, Python, gRPC, Docker, Kubernetes, GitHub Actions, Cloudflare, Caddy, Linux, and enough shell to remove unnecessary ceremony.
Work together
I am selective with consulting. Good fits: developer tooling, authentication, systems architecture, publishing pipelines, AI workflow infrastructure, and quiet high-leverage software for people who care about ownership.
