Demo profileBackend Developer - Authentication & Security
Bio
I make sure your users' data stays safe. 7 years implementing auth flows, JWT strategies, OAuth providers, and role-based access control. I think about edge cases like password reset token expiration and session hijacking. Systems Engineering degree, multiple security certifications, but I write code that's simple and auditable. I prefer boring, battle-tested solutions over clever hacks.
