Full-stack SaaS and platform products running in production. Real users, real infrastructure, real impact — built alone from a mobile command center in Texas.
Email Platform · Rust cell · tagos.email
Chat-speed mail on a real SMTP domain. Four-column UI (people → contexts → stream) with live inbound push, own Rust ingress/submission/egress path, and Sign in with Tagos (OIDC) for the ecosystem.
Live at tagos.email: host-terminated TLS, public MX, DKIM-signed egress from a dedicated Floating IP (warmup stage). Headless client core over protobuf TBP; Synapse multiplex for EMAIL_RECEIVED without full page reload.
