What complex projects have you worked on at the transport level?

At the transport layer in Go projects, it is common to work with protocols like TCP, UDP, as well as lower-level protocols, for example, implementing custom protocols on top of TCP or UDP for specific tasks.

Complex projects may include:

• Developing high-load network servers handling thousands of connections simultaneously.
• Implementing protocols with delivery guarantees, message ordering, and connection recovery.
• Creating proxy servers, load balancers, and VPN services.
• Optimizing performance and minimizing latency during data transmission.

For example, in a project to create a custom message exchange protocol over UDP, it was necessary to implement mechanisms for acknowledgment, retransmission, and packet ordering, which requires a deep understanding of the transport layer and network interaction features.
