I'm implementing Raft consensus from scratch in C++ with raw TCP sockets. Right now I'm working on a high-performance RPC client and server to keep network latency to a minimum. The main purpose of this project is to hone my systems programming skills and get more comfortable with distributed systems as well. One of the coolest things I've learned here is event-driven I/O with epoll and how event-loop architectures work in asynchronous setups.
