Delivered a production-grade tour & travel booking platform for a client, currently live. Built end-to-end at Bitstreaks Technology.
Loyalty System: Implemented a 3-tier cashback engine (Explorer → Traveller → Globetrotter) that automatically calculates and credits cashback to users on order success based on their tier status.
AI Automation (n8n + ChatGPT): Built a vendor-facing package creation pipeline — vendors can either add packages manually or paste any third-party travel website URL. n8n fetches the page source, ChatGPT extracts and structures the package details, and a new listing is auto-created on the platform. Eliminated manual data entry for vendors entirely.
