What Is Mark Hopper's Work at Microsoft and in Open Source?
Mark Hopper is a Senior Product Manager Architect at Microsoft focused on Windows development, and an open-source contributor and maintainer. His personal site, markhopper.info, is a portfolio of that work: Windows apps he builds and ships, TRMNL e-ink recipes, and links to Microsoft repositories he contributes to. If you want to know what he actually makes — rather than just his job title — the site's Projects section is the useful part, because it lists each project with its stack, status, and store links.
His role at Microsoft
The site describes him as "Sr. Product Manager Architect · Windows Developer · OSS Contributor/Maintainer." That combination matters for how you read the rest of the page: he works on Windows platform and developer-facing products at Microsoft, but the projects highlighted on markhopper.info are largely his own, not Microsoft products.
The one Microsoft-affiliated item listed is an official Microsoft repository:
- MGGraph Intune samples — an official Microsoft repository, listed under his projects.
Note the distinction the site makes: Task Scheduler Studio, barcodrod.io, and Lightwork are presented as his own Windows applications, while MGGraph Intune samples is explicitly labeled "Official Microsoft repository." The site does not claim Microsoft ownership of the personal apps.
Open-source projects on the site
The Projects section lists these, in the order shown:
| Project | Type | Stack | Status / notes |
|---|---|---|---|
| Task Scheduler Studio | Windows application | C#, WinUI 3, local MCP | Launched July 2026; Microsoft Store + source links |
| barcodrod.io | Windows application | C#, WinUI 3, .NET | Free, open source, actively maintained |
| Lightwork | Windows app | — | Work in progress |
| QRDecoder | Archived Windows project | — | Archived |
| Marvel Character of the Day | Public TRMNL recipe | — | — |
| Apple Note Board | Public TRMNL recipe | — | — |
| MGGraph Intune samples | Official Microsoft repository | — | — |
Task Scheduler Studio
A Windows app for finding, creating, and running scheduled tasks. According to the site, it provides a new interface over the Windows Task Scheduler service with a visual designer, search, and quick launch. You can see what's running and coming up, or create a task in plain language, and a local MCP server lets AI tools work with your tasks.
The site reports Microsoft Store figures checked September 12, 2026: 964 page views, 64 monthly active devices, and an average of 140 sessions over the last 30 days. A store review quoted on the page (from "Jack, United States") describes it as a good UI for task scheduling that also surfaced tasks the reviewer hadn't known were running.
barcodrod.io
A Windows app for reading, creating, and saving barcodes and QR codes. It reads codes from images, your camera, the clipboard, or whole folders; creates barcodes and Wi-Fi QR codes; and keeps a history. The site says it began as a small Python decoder and was rebuilt as a Windows app, and that it is free, open source, and actively maintained.
Store figures checked September 12, 2026: 13K installs over 12 months and 422 monthly active devices (30-day average), worldwide.
TRMNL recipes
Two public TRMNL recipes are listed: Marvel Character of the Day and Apple Note Board. These are recipes for the TRMNL e-ink display rather than Windows apps.
How to use the site
markhopper.info is a single portfolio page, not a documentation site or a product download hub. The practical path is:
- Open the Projects section to scan what exists and its status (active, work in progress, archived).
- For Task Scheduler Studio and barcodrod.io, follow the Microsoft Store link to install, or the Source link for the code.
- For the TRMNL recipes, use the recipe links directly.
- Use the Experience link if you want the Microsoft-side background rather than the projects.
One caveat worth stating plainly: the site does not publish pricing beyond barcodrod.io being described as free and open source, and it does not describe login requirements for any project. Don't assume the other apps are free or account-free just because one is — check the individual store listing.
What the page does not tell you
The excerpt covers project descriptions, stacks, status, and store metrics, but it does not include release notes, license text, system requirements, or support channels. If you need those, the Source and Microsoft Store links on each project are the next stop rather than the portfolio page itself.
