Software Developer

 I am a SQL developer with over 26 years experience, highly skilled in writing queries, views, procedures, functions, schema design of transactional and reporting databases. I can also help you with query performance, index creation, and execution plans.

I can help you setup, integrate and troubleshoot Microsoft Azure AD B2C in your applications and APIs. I have experience with implementing security (login) and API access with different applications using the Microsoft Identity Provider (IdP) Azure AD B2C with different clients including single page web applications (SPA) using the MSAL JS libraries which encompasses applications in JavaScript, Node JS, React, View, Angular, etc., in addition implementing IdP in APS .NET web applications, and setting up APIs to accept and validate tokens using the Microsoft IdP. I can help you implement various admin tasks such adding users to the AD B2C tenant using the Microsoft Graph API and setting up users flows for login, editing user account information and password reset. As such I have experience setting up Application and API registrations and scopes.
