Lana is a live SaaS product for service businesses that handle customer conversations and appointments through WhatsApp. I founded and built the web dashboard, backend, AI tools, billing and mobile companion.
The product brings a shared inbox, multi-professional calendars, customer records, confirmations and follow-ups into one system. Staff can take over a conversation and manage the same booking from web or mobile.
Bookings go through application tools. Business rules check the professional, time zone and existing appointments before confirming a time. Tenant-scoped data access keeps each business separate.
PostgreSQL holds operational records. Redis and BullMQ handle background work. Duplicate-safe Stripe events support subscription billing, while stored history and replayable events help web and mobile recover after disconnects.
I own product design, implementation, integrations, testing, deployment and ongoing operation. I use AI-assisted engineering and remain responsible for architecture, review and delivery.
Live product: lanaai.com.br. The public demonstration uses the real interface with synthetic data. Product code and customer information remain private.
