Full-Stack Developer — Fintech SaaS Platform Client Project
I built and launched a fintech SaaS platform from scratch as the sole technical owner. I owned the frontend, backend, database schema, REST API layer, authentication, role-based permissions, and production release.
I integrated Stripe payments, including webhook handling and the complete charge lifecycle. I validated successful and failure scenarios in Stripe Test Mode before cutting over to production keys for live transactions.
I performed end-to-end QA across frontend behavior, API responses, database state, and the deployment environment. I also set up CI/CD and AWS hosting and retained responsibility for production deployment and operational reliability.
