Description

Hi there!

Need a CTO who can translate geek-speak into boardroom English? I’m Dennis: 18-time Microsoft MVP, interim CTO/IT coach and lifelong C# nerd.

I drop in, diagnose fast, and deliver: platform modernisation in .NET & Azure, AI-powered features, crystal-clear 3- to 5-year tech roadmaps, and developer squads that whistle while they work.

Think of me as your temporary tech-sherpa: guiding you up the digital mountain, planting the flag, then handing you the map for the next climb.

Let’s chat!
