Cross-Platform Productivity Desktop Software

I’m commissioning a brand-new desktop application whose sole focus is boosting day-to-day productivity. The project starts with a fully featured desktop build, and the selected tech stack is up to you so long as the result feels smooth and modern; Electron, Qt, .NET MAUI, or any comparable cross-platform framework are all fine by me.

Although the first milestone is the desktop release, I want the architecture kept clean and modular because I plan to follow up with companion mobile versions on both Android and iOS. Designing reusable business logic and a UI that will scale down gracefully will save us time later.

Please include the following in your proposal:
• An outline of the framework or language you prefer and why it fits this job
• A short timeline for an MVP desktop build plus a rough idea of how you would later extend it to the two mobile platforms
• Any links to previous productivity tools, task managers, or similar software you have shipped

Deliverables for the initial phase:
• Executable desktop app (installer or package)
• Well-commented source code and build instructions
• Brief user guide or onboarding notes

Clean code, clear communication, and iterative demos are the keys to success here; if that workflow suits you, I’d love to hear how you would tackle the build.
