Looking for Open Source Co owners and decision makers

Hello, my name is Deadlight. I’m looking for developers who want to build something meaningful together, people who enjoy making technical decisions, sharing ideas, and working on ambitious open-source projects. Working alone slows down progress and limits perspective, so I’m hoping to find one or two co-owners who are passionate about systems programming, networking, privacy, and innovation. I’m currently working on two projects: Project 1: SwiftNet (Networking Library in C) A fast, reliable, dependency-minimal networking library written in C. Goals: High performance Every feature optional at compile-time Zero external dependencies at release Manual Ethernet/IP header construction Currently using libpcap, will switch to raw BPF Foundations are implemented, but the project is far from complete and not tested on real interfaces, only loopb

ack. https://github.com/deadlightreal/SwiftNet Project 2: SwiftCom (Self-Hosted Encrypted Messaging App) A privacy-focused messaging platform written in C++ with wxWidgets. Planned features: Self-hosted servers (no corporate ownership) Encrypted communication Chat rooms, DMs, and planned voice chat SQLite3 database Integrates with SwiftNet for full control over networking The project is about one month old. https://github.com/deadlightreal/SwiftCom Critical thinking: Someone who isn’t afraid to point out mistakes, question decisions, and challenge ideas when needed. I want a collaborator who improves the project and not someone who just agrees with everything. Technical baseline: Project 1: Solid understanding of sockets in C Experience with atleast TCP/UDP, packet structure (Bonus) Familiarity with raw sockets, libpcap, or BPF Project 2: Comfortable with C++ or GUI frameworks Creativity and new ideas: Not just implementing what exists, but proposing new features, optimizations, architectural improvements, and privacy-focused approaches. Motivation & passion: A collaborator who genuinely enjoys building systems from the ground up. Values: A strong belief in: Free speech, User autonomy, Maximum privacy, Decentralization, Open source freedom. Our goal is to build technology that empowers people and not corporations. If you are interested working on any of these projects and building something big together, please contact me at: Telegram: https://t.me/deadlightreal

Hello dear people, I’m working on SwiftNet, a small and easy-to-use C library for making networking communications in C straightforward. It’s a wrapper over Berkeley sockets with a simple API, readable, and easy to integrate. Right now, it’s only been tested on macOS, so I’m looking for contributors to: Test it on Linux Suggest improvements Help refine the design/API The codebase is pretty small, and while the API is straightforward, the internals are admittedly a bit rough right now. I’m still learning and improving! Why I built this: I wanted to create a C library that makes sending data over the network reliable and easy, while learning more about low-level networking and systems design. Everything is written in pure C, built with a basic CMake setup, and has no external dependencies. Example usage: // Server sends "hello" to every cli

ent that sends a message void server_message_handler(uint8_t* data, SwiftNetPacketServerMetadata* metadata) { swiftnet_server_append_to_packet(server, "hello", strlen("hello")); swiftnet_server_send_packet(server, metadata->sender); swiftnet_server_clear_send_buffer(server); } How you can help: Test on Linux: clone, build with cmake, and run the tests in /tests Suggest improvements to the overall library or code clarity Share ideas for future features Thanks for checking it out! Ask me anything. Repo: https://github.com/deadlightreal/SwiftNet
