Architectural Overview
As a core contributor to the iTravel platform, I focused on stability and revenue assurance. The challenge was handling global bookings with high reliability.
I engineered a fault-tolerant payment layer integrating Stripe with idempotent webhook handling, achieving a 99.8% transaction success rate. Additionally, I designed a secure, isolated Invoice Generation module that eliminated cross-tenant data leakage risks, a critical compliance requirement.
