At CrossAge Studio, I designed and shipped ArticleWriter, a publishing platform with a WinUI 3 desktop client, .NET API, and Razor front end. Its write and publish operations use client-certificate authentication, and it serves as the authoring surface for my technical blog.
At Nova College Beverwijk, I replaced a local development stack that was corrupting student coursework with a self-hosted .NET application; no further data loss was reported. Alongside DEMO IT!, I developed Super Shatter, a physics package that delivered a 17x performance gain over comparable mid-range solutions.
