At MediBuddy, I re-architected SSO authentication for 150+ live corporate clients, moving JWT validation, OTP verification, and redirect URL construction to the backend. I also replaced client-supplied SSO versioning with server-side configuration flags served through Redis.
I consolidated a login flow that required 7–8 sequential API calls into a backend-orchestrated sequence. For production issues, I replaced raw SQL with parameterized Sequelize ORM queries to restore login access for enterprise users, and moved UUID resolution into the caller service to improve identity-service performance.
I also fixed an SSO onboarding issue that restored sponsored healthcare benefits for users, and added database constraints that prevented invalid records and duplicate corporate-user entries. In personal projects, I built a hotel booking application with JWT authentication and a responsive real estate website using React and Tailwind CSS.
