Windows Desktop App Development

I need a custom desktop application built specifically for Windows. Once I shortlist candidates, I will share the full functional outline, but for now I can confirm that the project is green-field (no legacy code) and the end result should run smoothly on current Windows 10/11 installations without extra installs beyond the usual runtime packages. Please attach a detailed project proposal to your bid. I am especially interested in the architecture you would suggest (for example .NET 6 / WPF, Electron, or another modern Windows-friendly stack), the estimated timeline broken into clear milestones, and how you handle testing, packaging and post-launch maintenance. Past work links are welcome if they help illustrate similar desktop solutions you have delivered, but the proposal itself is the main factor I will evaluate. Deliverables will include: • Compiled installer or portable executable ready for user deployment. • Complete, well-commented source code and build instructions. • Brief usage guide or README so that non-technical staff can install and run the program. I reply quickly to clarifying questions, so feel free to ask if any requirement is unclear before you prepare your proposal.
