sendsms.ge Web Development Project

sendsms.ge is a bulk SMS service for businesses in Georgia — online shops, clinics, financial and delivery services that need to confirm an order, send a one-time code or run a promotion under their own recognisable sender name.

The platform covers the whole cycle: contact lists with import, personalised campaigns addressed by name, scheduled sending, automatic birthday and holiday greetings paid for in advance, and delivery reports with the exact time of arrival. Segmentation follows the GSM 03.38 and Unicode rules — a single Georgian letter pushes the whole text to Unicode, so the cost shown while typing is exactly the cost charged.

Integration is through a REST API in an smsoffice-compatible format, so moving existing code is a matter of changing the address. Every sender name has its own API key and its own delivery callback, which lets one account serve several projects. Balance is topped up through Bank of Georgia payments. A Flutter Android app carries the full panel.

Security is built in: token authentication, 60 requests a minute per key, idempotency against repeated sends, atomic balance debiting inside a transactional lock, a stop list and recorded opt-outs. The server runs ufw and fail2ban, with SSH by key only.
