Professional Phone Repair Software Development

Request for Proposal (RFP): Development of a Professional Phone Repair Desktop Tool (Backend in C++, UI in WPF)

Dear Developers,

I hope this message finds you well.

We are looking to build a professional-level desktop application for advanced smartphone repair operations, targeting both Android and Apple devices. Tasks include flashing, FRP unlocking, IMEI repair, dead boot recovery, backup, and other advanced procedures.

We already have a fully working prototype in C#, along with complete UI/UX designs. Now we want to rebuild the project from scratch in C++ (core logic & DLLs) and use WPF for the frontend to ensure high performance, security, and scalability.
