Do you have experience working with proxy services and VPN protocols?

Yes, I have experience working with proxy services and VPN protocols at the development and integration level.

I have worked with configuring and using proxy servers for traffic routing, load balancing, and security. Familiar with SOCKS5, HTTP/HTTPS proxy protocols, able to configure proxy servers and integrate them into client applications in Go.

Regarding VPN protocols — familiar with OpenVPN, WireGuard, IPsec. Understand the principles of tunneling, encryption, and authentication. In projects, I have implemented client and server VPN components in Go, using libraries for network socket and cryptography work.

For example, for WireGuard, you can use the golang.zx2c4.com/wireguard/wgctrl library to manage WireGuard interfaces from Go code.

I also have experience writing proxy services in Go that intercept and modify HTTP requests, implement caching, and authentication.
