@shivambhardwaj3

Senior Android Developer at PayPal building secure authentication, passkey, and account security features.

At PayPal, I build features for the consumer Android app, focusing on secure authentication and account security. I created secure session transfer for the move from WebView to native screens, keeping users signed in with OAuth 2.0 and PKCE.

At T-Mobile, I built features for a business calling and messaging app, including peer-to-peer voice and video calling with Google WebRTC. Earlier, at D & A Technologies, I delivered app features and updates for clients including Tapping Solution and Phlex Edge.
