arcline-portal

Customer dashboard for arclineit.com. Provides SSL expiry monitoring and a support ticket system — without requiring customers to SSH into anything.

Sits alongside WHMCS for billing; handles everything WHMCS doesn't.

Stack

• Go backend, vanilla HTML/CSS/JS (Arcline design system)
• SQLite (single file, no server required)
• Session-based auth (bcrypt + secure cookies)
• Ships as a single binary with embedded static assets and templates

Modules

SSL Expiry Dashboard

Customers add domains; the system checks cert expiry daily via TLS dial and displays status color-coded: green > 30d, amber 14–30d, red < 14d.

Support Tickets

Customer opens a ticket; Blake gets an email. Replies go back into the thread from the portal UI. No third-party helpdesk.
