Digital wedding invitations with a range of ready-to-use templates (including a Doraemon theme), a dashboard to track invitation status & RSVPs, and a guest blasting system via email and social media.
Helpdesk - Tech Monitoring
An automated chat response system that immediately follows up on customer reports, improving transparency and customer trust.

An internal daily expense tracker with custom categories, a real-time balance dashboard, and an AI chat assistant to help analyze income and spending.
