I have extensive experience in resolving authentication-related issues across multiple applications. Over the years, I have worked on implementing and troubleshooting various authentication mechanisms, including token-based authentication (JWT), OAuth, and session management. My expertise includes identifying and addressing vulnerabilities, ensuring secure user access, and integrating robust authorization frameworks. I have successfully debugged and resolved issues such as token expiry, role-based access inconsistencies, and API authorization errors. By collaborating with cross-functional teams, I have ensured seamless and secure authentication workflows for end users. I am confident in effectively addressing and fixing authentication challenges for your application as well.
