Backend Stabilization for JAMWRK

JAMWRK is a production-focused music learning and community platform where I worked on backend engineering, payment infrastructure, authentication, and stabilization of an AI-generated codebase.

I took ownership of the Stripe integration and backend reliability, reviewing and refactoring complex AI-generated code to make critical payment workflows reliable and production-ready. I implemented and stabilized Stripe Premium subscriptions, Stripe Connect teacher payouts, JAMWRK platform commissions, and payment webhook processing, including idempotency, failed webhook scenarios, and edge cases around payment events.

I also worked on the COPPA / Guardian verification workflow for younger users, integrating the required authorization logic with the platform's authentication and payment flows. On the authentication side, I configured and tested Firebase Authentication, email verification, password-related flows, and custom transactional email infrastructure.

A major part of the project involved human review and debugging of AI-generated Replit code. I traced existing backend logic, identified inconsistencies and integration issues, fixed production bugs, and validated the workflows through real Stripe transactions and repeated QA testing.
