I'm a software architect who enjoys turning messy real-world problems into clear, deterministic systems. Lately, I’ve been mixing code, cycling, and simulation.

• Software architecture & platform design
• Content Management Systems (CMS) — building them since the late ’90s
• Umbraco architecture, extensions, and large-scale CMS platforms
• Deterministic models, simulations, and constraints-based systems
• CLI-first tools, automation, and developer experience
• DevSecOps and secure-by-design platforms
• Endurance sports, training data, and performance modeling

A CLI tool that generates realistic Team Time Trial training workouts for Zwift.

Why it’s interesting:

• Queue-based, deterministic rotation model
• Per-rider workout generation from a shared team plan
• FTP-based power modeling with realistic transitions
• Focus on testability, invariants, and reproducibility
• No UI by design — output is validated .zwo files

• Simple models beat clever abstractions
• Determinism makes systems testable and explainable
• Constraints are a feature, not a limitation
• Tooling should adapt to humans, not the other way around
• Communities matter — good ideas scale better when they’re shared

I’m a software architect and lead for Umbraco-based platforms at the Council of the European Union, working across multiple business domains and long-lived systems.

Earlier in my career, I was deeply involved in the .NET community:

• User group lead and conference organizer
• Author of technical books, including the first book published on ASP.NET MVC
• Microsoft MVP for 8 consecutive years

I still enjoy sharing ideas, mentoring, and building things — with a strong focus on systems that are designed to age well.
