Worked on the medusajs/medusa repository to enhance payment security by addressing a vulnerability in webhook handling. Focused on backend development using TypeScript, the work introduced stricter validation in the processPaymentWorkflow to ensure that payment webhooks without a valid session_id could not complete or interfere with unrelated carts. This involved tightening the logic in both the core workflow and the Stripe integration, as well as expanding test coverage with integration and unit tests to guard against sessionless events. The changes improved payment data integrity, reduced fraud risk, and demonstrated strong skills in API integration, testing, and secure webhook architectures.
