Sometimes, copying from existing operating systems (especially pedagogical ones) is a good places to start: Nachos, Minix (esp paired with Tanenbaum's OS book), Xv6, or ToyOS might be good reference material for you. Source: almost 2 years ago

Tunneling services can be considered as a solution in some cases. Services like ngrok, frp, localtunnel and sish create a public endpoint that tunnels communication to your local endpoint via a tunnel client. - Source: dev.to / about 1 year ago

Why not forget about Cloudflare and a VPN but get a 3 euro Hetzner server and install https://github.com/antoniomika/sish for dynamic DNS through SSH + Traefik with a DNS resolver and have yourself a wildcard certificate.
