What I Built

Daphq is a robust, open-source, cross-platform file transfer application engineered entirely from scratch to deliver hardware-saturating speeds over local area networks (LAN), Wi-Fi, and Mobile Hotspots.

As a solo developer, I built Daphq to solve a personal frustration: the bloated overhead, privacy concerns, and artificial speed limits of conventional HTTP-based or cloud-reliant file-sharing tools. Daphq bypasses the standard Web/REST layer completely, establishing direct, bare-metal TCP Sockets ( Socket & ServerSocket ) with SocketOption.tcpNoDelay enabled to eliminate protocol latency and push network hardware to its absolute physical limits.

Built using Flutter (Dart) for seamless cross-platform performance (currently native on Android and Windows), Daphq features a highly decoupled architecture using the BLoC/Cubit pattern, multi-gigabyte memory protection guards, and background network synchronization, and intelligent user…
