Infrastructure / messaging
Wraith
One endpoint. Text in, nothing else out.
A self-hosted bridge from Make to a single WhatsApp group that can’t be pointed anywhere else: callers send message text, never a phone number or chat ID, and the service fails closed if the group name isn’t unique. Session state is encrypted at rest, requests are rate- and size-limited, and the logs never contain a message. It runs in production as a systemd service behind Caddy.
Role: Design, build and production deployment as a systemd service behind Caddy TLS
