Raincheck

Inspiration Tour operators lose thousands in revenue when weather forces cancellations. Having worked in travel tech and owned a call center, I knew the pain of manually calling 50+ customers to reschedule. Raincheck automates this entire process. What I Learned

Building voice AI agents that sound natural and handle dynamic conversations Integrating multiple APIs (FareHarbor, Composio, Vapi) into a cohesive workflow Creating truly autonomous systems that make decisions without human intervention

How I Built It Used Claude Code to create specialized agents for each component: weather monitoring, availability checking, voice calls, and UI. Each agent worked independently but coordinated through a central Ruby/Sinatra app. The system monitors weather → decides cancellations → finds alternatives → calls customers automatically.
